Hey PaperLedge learning crew! Ernis here, ready to dive into another fascinating piece of research. Today, we're exploring how well computers understand language, and more importantly, how their understanding compares to our own brains. It's like pitting a super-smart robot against a seasoned bookworm in a reading comprehension contest!
So, the paper we're looking at is all about language models – think of these as computer programs designed to predict the next word in a sentence. They're the brains behind things like autocomplete on your phone and those AI chatbots you might have chatted with. These models have gotten incredibly sophisticated lately, thanks to something called Natural Language Processing, or NLP. It's a field that's been exploding with new advancements.
Now, neuroscientists are super interested in these models because they can help us understand how we process language. It's like using a map to understand a territory. The better the map, the better we understand the territory!
Previous research has shown that simpler language models can somewhat predict where our eyes linger when we're reading. This "eye-lingering" is called Gaze Duration, and it's a pretty good indicator of how difficult or surprising a word is. If a word is predictable, we glance over it quickly. If it's unexpected, our eyes tend to stick around a bit longer.
Think about it like this: If I say "Peanut butter and...", you probably already know I'm going to say "jelly." Your eyes probably won't spend much time on "jelly" because it's so predictable. But if I said, "Peanut butter and... pickles!", your eyes would probably widen, and you'd stare at "pickles" for a second, right?
This study takes things a step further. The researchers wanted to see how the really fancy, cutting-edge language models stack up – specifically, models like GPT2, LLaMA-7B, and LLaMA2-7B. These are the rockstars of the language model world! They're based on something called "transformer" architecture, which is like giving the models a super-powered brain upgrade.
The researchers had people read text in Rioplantense Spanish (that's the Spanish dialect spoken in the Rio de la Plata region of South America). They tracked the readers' eye movements and then compared those movements to what the language models predicted the readers would do.
And guess what? The fancy transformer models did a better job than the older, simpler models at predicting gaze duration. It's like the AI is getting better and better at anticipating what we're going to read!
Here's the kicker, though: even the best language models couldn't fully explain why human readers' eyes moved the way they did. There's still a gap between how computers predict language and how humans actually process it. It's like the AI might be good at predicting the plot of a movie, but it doesn't quite understand the emotional nuances the way we do.
"Despite their advancements, state-of-the-art language models continue to predict language in ways that differ from human readers."
So, what does this all mean? Well, it tells us that while AI is getting smarter and smarter, it's not quite human yet. Our brains are still doing something special when it comes to language comprehension. It also suggests that these language models aren't perfectly mirroring human cognition, which is important to remember when we're using them to study the brain!
Why does this research matter? Well, for:
AI developers: It highlights areas where language models still need improvement.
Neuroscientists: It gives them a better understanding of how the brain processes language.
Educators: It reminds us that human understanding is still unique and valuable.
Everyone: It's a fascinating glimpse into the complex relationship between humans and technology!
Here are a few questions that popped into my head while reading this paper:
If AI models are getting better at predicting our reading patterns, could they eventually be used to personalize our reading experiences in a way that enhances comprehension?
What are some of the factors that humans consider when reading that current language models aren't taking into account? Is it emotion, context, or something else entirely?
Could studying the differences between AI and human language processing help us better understand and treat language-based learning disabilities?

Alright Learning Crew, Ernis here, ready to dive into some fascinating research! Today, we're unpacking a paper that looks at how we can use the power of Large Language Models, think super-smart AI text generators, to predict future events based on what's happening in the world right now.
Imagine you’re trying to understand a complex news story. You might break it down into simple pieces: who did what to whom, and when it happened. Researchers are doing something similar, but on a much larger scale.
They're taking real-world events and turning them into these little packages called "quadruples." Each quadruple contains four pieces of information: the subject (who's doing something), the relation (what they're doing), the object (who or what they're doing it to), and a timestamp (when it happened). Think of it like a little news headline condensed into data. For example: "Elon Musk (subject) bought (relation) Twitter (object) in 2022 (timestamp)."
Sometimes, they even add a fifth piece – a short text summary describing the event – making it a "quintuple." This gives the AI even more context.
Now, traditionally, researchers have used things like graph neural networks (GNNs) and recurrent neural networks (RNNs) – basically, complex computer programs – to look at these quadruples and quintuples and try to predict what might happen next. These are like intricate webs that map out relationship and patterns over time.
But this paper asks: what if we could use those big, powerful Large Language Models (LLMs) instead? The kind that can write essays and answer complex questions? Can they do just as well, or even better, at predicting future events?
That's where LEAP comes in. This paper proposes a new framework, called LEAP, that uses LLMs to predict events. Think of LEAP as a system that asks the LLM questions based on the event data.
For example, if we know "Elon Musk bought Twitter in 2022," LEAP might ask the LLM: "Given that Elon Musk bought Twitter in 2022, what might happen next related to Elon Musk and Twitter?"
"LEAP leverages large language models as event predictors."
The researchers designed clever "prompt templates" to help the LLM understand the questions and give the best possible answers. It's like training the LLM to be a super-powered event forecaster!
What's really cool is that, for predicting multiple events in the future, LEAP uses a simplified approach. Instead of those complex GNNs and RNNs, it uses the LLM to create a sort of "snapshot" of each event, then uses a simpler system to analyze those snapshots and predict future relationships. This makes the whole process more efficient.
So, why does this matter?
For Businesses: Imagine predicting supply chain disruptions or shifts in consumer behavior.
For Policymakers: Think about forecasting potential social unrest or economic downturns.
For Everyday Life: Perhaps even anticipating trends in technology or the stock market.
The researchers tested LEAP on real-world datasets and found that it works really well! In some cases, it performed just as well as, or even better than, the traditional methods, while being simpler to implement.
This research suggests that LLMs could revolutionize how we predict future events, making it easier and more accessible for everyone.
Here are a couple of things I'm wondering:
Given that LLMs are trained on existing data, could this approach inadvertently perpetuate existing biases when predicting future events?
How adaptable is LEAP to completely novel events or situations that haven't been well-documented in the past?
That's all for this episode, Learning Crew! Let me know what you think about using LLMs for event prediction. Until next time, keep learning!Credit to Paper authors: Libo Zhang, Yue Ning

Multiagent Systems - Empowering Scientific Workflows with Federated Agents
Friday May 09, 2025
Friday May 09, 2025
Hey PaperLedge crew, Ernis here, ready to dive into some seriously cool AI tech! Today, we're cracking open a paper about something called "Academy," and trust me, it's way more exciting than it sounds. Think of it as a super-powered air traffic control system, but instead of planes, it's managing AI agents doing groundbreaking science.
So, what are "agentic systems"? Imagine a team of super-smart robots, each specializing in a different task, all working together to solve a really tough problem. That's the basic idea. These systems are becoming super popular in AI, but there's been a snag: they haven't been able to play nicely with the massive computing power we use for scientific research – things like supercomputers and giant data banks.
That's where Academy comes in. It's a piece of software designed to bridge that gap. The researchers built Academy to be a flexible platform that can deploy these AI agents across all sorts of scientific resources. Think of it like a universal adapter that lets your AI team plug into any scientific instrument or supercomputer.
Now, why is this such a big deal? Well, consider the kinds of challenges scientists are tackling these days:
Discovering new materials: Imagine AI agents sifting through millions of combinations to find the perfect material for, say, a super-efficient solar panel.
Decentralized learning: This is like having different AI agents, each trained on a small piece of a giant dataset, collaborating to build a much smarter overall system. It's like a group of specialists combining their knowledge to solve a complex puzzle.
Information extraction: Think of AI agents that can automatically pull out key information from tons of scientific papers, helping researchers stay on top of the latest discoveries.
Academy allows these types of applications to run on large-scale computing resources, making them much more effective.
The paper highlights a few key features of Academy that make it ideal for scientific computing:
Asynchronous execution: Agents can work independently and at their own pace. It's like a team where everyone can focus on their own tasks without constantly waiting for others.
Heterogeneous resources: Academy can handle different types of computing resources, from high-performance computers to experimental facilities.
High-throughput data flows: Academy is designed to handle massive amounts of data.
Dynamic resource availability: It can adapt to the constantly changing availability of resources.
The team even ran some tests to show how well Academy performs, and the results are promising. It's fast, scalable, and capable of managing complex workflows.
So, why should you care about this? Well, if you're a:
Scientist: This could revolutionize how you conduct research, allowing you to automate complex tasks and accelerate discoveries.
AI developer: Academy provides a powerful platform for building and deploying agentic systems in the scientific domain.
Anyone interested in the future of AI: This is a glimpse into how AI can be used to solve some of the world's most pressing challenges.
"Academy is designed to deploy autonomous agents across the federated research ecosystem."
This research brings up some interesting questions for us to consider:
As AI becomes more integrated into scientific discovery, how do we ensure that these systems are used ethically and responsibly?
Could platforms like Academy democratize access to advanced computing resources, allowing smaller research teams to compete with larger institutions?
What new scientific breakthroughs might be possible if we can truly unleash the power of AI agents across the scientific landscape?
That's it for this episode's paper deep-dive! Hopefully, you now have a better understanding of what Academy is and why it matters. Until next time, keep exploring and keep learning!Credit to Paper authors: J. Gregory Pauloski, Yadu Babuji, Ryan Chard, Mansi Sakarvadia, Kyle Chard, Ian Foster

Hey PaperLedge crew, Ernis here, ready to dive into some seriously cool tech! Today, we're talking about making our phones even smarter using the power of AI, but doing it in a way that doesn't break the bank or drain our batteries. Think of it like this: you've got a super-smart friend, let's call him Professor Cloud, who can solve any problem, but he lives far away and every time you ask him something, it costs you a little bit of money and takes a while to get an answer.
Now, imagine you also have two local friends, let’s call them Speedy and Watchful. Speedy is great at doing things quickly, but isn't so bright. Watchful is good at noticing details and reporting back, but isn't great at coming up with plans. This paper introduces something called EcoAgent, which is like a team effort between Professor Cloud, Speedy, and Watchful to get things done on your phone.
So, what's the problem EcoAgent is trying to solve? Well, these super-smart AIs, called Large Language Models (LLMs), are amazing at figuring things out. They can automate tasks on your phone like booking a flight or ordering groceries, but they usually live in the cloud. This means every little step requires sending data back and forth, which takes time and costs money because you're using the cloud provider's resources, kind of like calling Professor Cloud all the time.
The alternative? You can use smaller, faster AIs directly on your phone. These are like Speedy and Watchful. But these smaller AIs often aren't as smart or as good at handling complex tasks. It's like asking Speedy to plan a surprise party – it might not go so well.
Problem: Cloud AIs are smart but slow and expensive.
Problem: On-device AIs are fast but not as smart.
Here's where EcoAgent comes in to save the day! It's a system that combines the strengths of both cloud and on-device AIs. Think of it as a well-coordinated team:
Professor Cloud (Planning Agent): This cloud-based AI is the brains of the operation. It's responsible for making the overall plan, like figuring out the steps to book that flight.
Speedy (Execution Agent): This on-device AI executes the plan. It actually taps the buttons and navigates the apps on your phone.
Watchful (Observation Agent): This on-device AI watches what's happening on the screen and reports back if something goes wrong. It's like a quality control expert ensuring everything goes smoothly.
The real magic is how they work together. Watchful has a special trick: it can quickly summarize what's on the screen into a short text description. This keeps the amount of data sent to Professor Cloud super small, saving time and money. It's like Watchful sending Professor Cloud a quick memo instead of a detailed report with screenshots.
"EcoAgent features a closed-loop collaboration among a cloud-based Planning Agent and two edge-based agents... enabling efficient and practical mobile automation."
And what happens if Speedy messes up? That's where the "Reflection Module" comes in. If Watchful sees something go wrong, it sends a message to Professor Cloud along with a history of what happened on the screen. Professor Cloud then uses this information to re-plan the task, figuring out what went wrong and how to fix it. It's like Professor Cloud reviewing the security camera footage to see what caused the problem.
The researchers tested EcoAgent on a simulated Android environment and found that it was able to complete tasks successfully just as often as using a cloud AI alone, but with significantly less data being sent to the cloud. This translates to lower costs and faster response times!
So, why should you care? Well, if this technology becomes widespread, it could mean:
Smarter phone automation: Imagine your phone automatically handling repetitive tasks with ease.
Lower data usage: Less data being sent to the cloud means lower mobile data bills.
Faster response times: Tasks get done quicker because the system is more efficient.
More privacy: Processing more data on your device could mean less data being sent to third-party servers.
This research is a step towards making powerful AI more accessible and practical for everyday mobile use. It's about finding the right balance between cloud and edge computing to create a seamless and efficient user experience.
Here are a few things that got me thinking:
How easily could this system be adapted to different operating systems or even different types of devices, like smartwatches?
What are the potential security risks of having AI agents interacting with our apps and data, and how can we mitigate them?
Could this collaborative approach be applied to other areas beyond mobile automation, like robotics or smart home devices?

Hey PaperLedge listeners, Ernis here, ready to dive into some seriously cool tech! Today, we're exploring a paper that tackles a challenge many of us might face as virtual and augmented reality become more commonplace: how do we effectively talk to the AI assistants popping up in these digital worlds?
Think of it like this: You're wearing a VR headset, building a virtual Lego castle. You want the AI assistant – let's call it "BrickBot" – to add a tower. Now, you could try to describe the exact location of that tower using just words. "BrickBot, place a cylindrical tower three inches to the left of the main gate, five inches up, and angled slightly inward..." Sounds clunky, right?
That's the problem this research addresses. Communicating precise spatial information – position, size, direction – using only text or voice in a 3D environment is tough! It puts a strain on our brains, making the whole VR experience less intuitive and more frustrating. It's like trying to explain how to tie a knot over the phone – much easier to just show someone!
Enter GesPrompt! This paper introduces a clever solution: combining speech with gestures. Imagine you're back in that virtual Lego world. Instead of a wordy description, you simply point to where you want the tower, maybe draw a circle in the air to indicate its size, all while saying "BrickBot, put a tower here."
The researchers developed a system that understands both your words and your hand movements. It's like your virtual assistant suddenly speaks fluent "body language"!
"By incorporating gestures, GesPrompt extracts spatial-temporal reference from co-speech gestures, reducing the need for precise textual prompts and minimizing cognitive load for end-users."
That quote, while a bit technical, basically means that by letting you use your hands, GesPrompt reduces the mental effort needed to communicate with the AI.
So, what did these researchers actually do? They essentially built a VR system that can interpret gestures alongside speech. Here’s a quick breakdown:
They created a workflow – a set of instructions – for integrating gesture and speech input within a VR environment. Think of it like a recipe for making gesture-aware VR.
They built a prototype VR system based on that workflow. It's the real-world implementation of their idea.
They conducted a user study to see if GesPrompt actually made things easier. And guess what? It did! People found it much more natural and effective to communicate with the AI assistant using gestures and speech together.
Why is this important?
For gamers and VR enthusiasts: This could lead to more immersive and intuitive VR experiences. Imagine building worlds, solving puzzles, or even collaborating with others in VR, all with the ease of natural gestures.
For educators and trainers: Imagine medical students learning surgical procedures in VR, using gestures to manipulate virtual instruments and interact with AI tutors.
For accessibility: This technology could open up new possibilities for people with disabilities, allowing them to interact with virtual environments in ways that might not be possible with traditional interfaces.
This research is a step towards a future where interacting with AI in XR feels as natural as talking to a friend. It bridges the gap between the digital and physical worlds, making VR and AR more accessible and enjoyable for everyone.
Now, a couple of questions that popped into my head while reading this paper:
How well does GesPrompt work in noisy environments, where speech recognition might be less accurate? Does it rely more on gestures in those situations?
Could this technology be adapted to other devices, like AR glasses or even smartphones, to provide more intuitive interfaces for everyday tasks?
That's all for today's deep dive into GesPrompt! I hope you found it as fascinating as I did. Until next time, keep exploring the frontiers of tech!Credit to Paper authors: Xiyun Hu, Dizhi Ma, Fengming He, Zhengzhe Zhu, Shao-Kang Hsia, Chenfei Zhu, Ziyi Liu, Karthik Ramani

Hey PaperLedge learning crew, Ernis here! Today we're diving into a fascinating paper about making our conversations with AI smoother and more helpful. Think about those times you've asked Siri or Alexa something, and it just… didn't quite get it. Well, researchers are working hard to fix that!
This paper introduces something called Clem Todd. Now, don't let the name intimidate you. It's basically a well-organized playground for testing out different ways to build better conversational AI. Imagine it like this: you're trying to bake the perfect cake. Clem Todd is your kitchen, complete with standardized ingredients, measuring tools, and ovens. It allows you to try different recipes (AI systems) using the same conditions, so you can really see what works best.
The problem the researchers are tackling is that everyone has been testing their AI conversation systems in different ways. One group might use one type of simulated user to chat with their system, while another uses a totally different one. It's like comparing apples and oranges! It's hard to know which system is really better.
“Existing research often evaluates these components in isolation… limiting the generalisability of insights across architectures and configurations.”
That's where Clem Todd comes in. It provides a consistent environment. It lets researchers plug in different "user simulators" (AI that pretends to be a person having a conversation) and different "dialogue systems" (the AI trying to help you), and compare them fairly. Think of user simulators as different customer personalities - some are very direct, others are more polite and vague.
So, what did they actually do with Clem Todd? They re-tested some existing AI conversation systems and also added in three brand new ones. By putting them all through the same rigorous testing, they were able to get some really valuable insights.
For example, they looked at how things like the size of the AI model, the way it's designed (its "architecture"), and the specific instructions given to it ("prompting strategies") affect how well it performs in a conversation. It's like figuring out if adding more flour, using a different type of mixer, or changing the oven temperature makes a cake taste better.
Why does all this matter? Well, if you're building a chatbot for a business, Clem Todd can help you choose the best approach. If you're a researcher, it provides a standardized way to compare your new ideas to what's already out there. And for all of us, it means we can look forward to having AI assistants that are actually helpful and understand what we're trying to say!
For businesses: Helps build more effective chatbots and virtual assistants.
For researchers: Offers a standardized platform for evaluating new dialogue systems.
For everyone: Leads to better and more helpful AI interactions.
Now, this research raises some interesting questions for us to ponder:
If we can simulate users so well, are we getting closer to creating AI companions that truly understand our needs and emotions?
Could a standardized framework like Clem Todd actually stifle creativity by limiting the types of AI systems researchers are willing to explore?
As AI conversation gets better, how do we ensure it's used ethically and doesn't replace human connection?
That's all for today's episode. I hope you found this breakdown of Clem Todd insightful. Until next time, keep learning!Credit to Paper authors: Chalamalasetti Kranti, Sherzod Hakimov, David Schlangen

Hey everyone, Ernis here, and welcome back to PaperLedge! Today, we're diving into some fascinating research about how computers are learning to "see" and "think" at the same time. Think of it like this: imagine trying to describe a painting to someone who's never seen it. You need both the ability to see the colors, shapes, and details, and the ability to reason about what it all means and put it into words. That's essentially what these Vision-Language Models, or VLMs, are trying to do.
This particular paper looks at how we can combine these two abilities – visual perception and language reasoning – in a really clever way: by literally merging the brains of different AI models! Now, I know that sounds like something out of a sci-fi movie, but stick with me...
The researchers focused on something called model merging. It's kind of like taking two LEGO sets – one that's really good at building cars (representing visual perception) and another that's great at building houses (representing language reasoning) – and figuring out how to combine the pieces so you can build both cars and houses using the same set. Instead of LEGO bricks, we're talking about the parameters inside these AI models.
What's really cool is that they merged models that were good at different things. Usually, people merge similar models. But these researchers merged a model that was great at seeing with a model that was awesome at thinking and talking. And they did it without having to retrain the models, which is a huge time-saver!
"Model merging offers a successful pathway to transfer reasoning abilities from LLMs to VLMs in a training-free manner."
The result? They found that the merged model could now do a better job of both seeing and reasoning than either of the original models could do on their own! It's like giving someone a pair of glasses and a really good textbook – they can see the world more clearly and understand it better too.
But the researchers didn't stop there. They wanted to understand how this merging process actually worked inside the model. So, they peeked under the hood, so to speak, to see which parts of the model were responsible for which tasks.
They discovered that the early layers of the model were mostly focused on visual perception – identifying shapes, colors, and objects. Think of it as the part of your brain that processes the raw sensory data from your eyes. The later layers, on the other hand, were more involved in reasoning – understanding the relationships between objects, drawing inferences, and generating language. This is like the part of your brain that puts everything together and figures out what it all means.
Here's where it gets really interesting: After merging the models, they found that all the layers started contributing to reasoning, whereas the perception capabilities were still mostly handled by the early layers. It's like the entire brain became more engaged in the thinking process, while the basic visual processing remained largely the same.
Imagine you're learning to play a musical instrument. At first, you're just focused on hitting the right notes (perception). But as you get better, you start to understand the music theory behind it, and you can express yourself more creatively (reasoning). This research suggests that model merging can help AI models make that same kind of leap.
So, why does all this matter? Well, there are tons of potential applications! Imagine:
For Doctors: AI that can analyze medical images and understand the context to make better diagnoses.
For Self-Driving Cars: Cars that can not only "see" the road but also "understand" what's happening and make smarter decisions.
For Accessibility: AI that can describe images to visually impaired people in a rich and meaningful way.
This research is a big step towards building AI that's not just good at recognizing things, but also at understanding them. And that's a future we can all look forward to.
Now, here are a couple of things I've been pondering:
Could this model merging technique be used to combine even more diverse AI models, like those that specialize in audio or even tactile sensing?
What are the ethical implications of creating AI models that are so good at both seeing and reasoning? How do we ensure that these models are used responsibly and don't perpetuate biases?
That's all for today's episode! I'd love to hear your thoughts on this research. What other applications can you imagine for VLMs, and what are some of the challenges we need to address as we develop this technology?

Computation and Language - ComPO Preference Alignment via Comparison Oracles
Friday May 09, 2025
Friday May 09, 2025
Hey learning crew, Ernis here, ready to dive into some fascinating research! Today, we're unpacking a paper that tackles a really important challenge in the world of Large Language Models – think ChatGPT, Gemini, and the like.
Now, we all want these AI assistants to be helpful and aligned with what we humans actually prefer, right? That's where "alignment" comes in. Imagine teaching a dog new tricks. You want them to learn what's "good" (sitting on command) and "bad" (chewing your shoes).
Traditionally, we've been using methods called "direct alignment" to teach these LLMs. The problem? Sometimes, the "good" and "bad" examples we give them are too similar. It's like telling the dog, "Almost sat! Good boy... but not quite!" It gets confusing.
This confusion leads to two main problems that the paper highlights:
Verbosity: The models become overly wordy, trying to cover all bases because they're not sure what exactly we want. Think of it as the AI equivalent of rambling!
Likelihood Displacement: The model starts to think that the slightly worse answer is almost as good as the best answer. This is like the dog thinking chewing on a corner of your shoe is okay because it's not the whole shoe.
So, what did these researchers do? They came up with a new method for aligning LLMs that's based on what they call "comparison oracles." Think of an oracle as a really smart judge. Instead of just giving the LLM "good" and "bad" examples that might be too close, the oracle helps the model directly compare different responses and figure out which one is clearly better.
It's like showing the dog two treats, one really tasty and one just okay, and letting them choose. The choice is obvious, and the lesson sticks better!
The researchers also proved, using some fancy math, that their method is guaranteed to work – at least in its basic form. That is, it’s guaranteed to converge to the right alignment.
But wait, there's more! They didn't just stop at the theory. They then tweaked and improved their method using some clever "tricks of the trade" – what they call "heuristics" – to make it even better in the real world.
They tested their new method on several popular LLMs, including Mistral-7B, Llama-3-8B, and Gemma-2-9B, using some well-known benchmarks like AlpacaEval 2, MT-Bench, and Arena-Hard. And guess what? Their method worked! It helped these LLMs perform better, even when the "good" and "bad" examples were noisy and confusing.
"A highlight of our work is that we evidence the importance of designing specialized methods for preference pairs with distinct likelihood margin..."
Basically, they showed that it's crucial to have different strategies for teaching the LLM when the difference between the good and bad answer is huge versus when it's really subtle. That makes sense, right?
So, why does this matter to you, the PaperLedge listener?
For everyday users: This research leads to AI assistants that are more helpful, less verbose, and better aligned with your actual needs. Think fewer rambling responses and more spot-on answers!
For developers and researchers: This paper provides a valuable new tool for aligning LLMs and overcoming the limitations of existing methods. It's like a new and improved hammer for building better AI.
For anyone interested in the future of AI: This research pushes the boundaries of what's possible with LLMs and helps us create AI that's more aligned with human values and preferences.
Here are a couple of things that got me thinking while reading this paper:
How can we make these "comparison oracles" even smarter and more efficient? Could we use other AI systems to help judge the quality of LLM responses?
What are the ethical implications of aligning LLMs with human preferences? Whose preferences should we prioritize, and how do we avoid bias?
That's all for today's paper breakdown! I'm excited to hear your thoughts on this research. Let me know what you think in the comments!Credit to Paper authors: Peter Chen, Xi Chen, Wotao Yin, Tianyi Lin
