Alright, learning crew, Ernis here, ready to dive into another fascinating paper that's got me thinking! Today, we're talking about how smart those super-powered AI models really are, and I mean the big boys, the ones like OpenAI's o3.
We all know they can write poems, code, and even ace some exams, but are they true experts? Can they tackle the kind of brain-bending problems that real-world researchers grapple with daily? This paper sets out to answer just that.
So, instead of throwing these AI models another set of coding puzzles (which, let's be honest, they're getting pretty good at), these researchers created a new challenge called FormulaOne. Now, this isn't about racing cars, although it's just as intense! Think of it as a super complex puzzle that lives at the intersection of a few big ideas:
Graph Theory: Imagine maps of cities, social networks, or even computer networks. Graph theory is all about understanding the connections between things.
Logic: You know, good old-fashioned reasoning! Figuring out "if this, then that" scenarios.
Algorithms: Step-by-step instructions for solving problems, like a recipe for a computer.
The cool thing is, all this stuff is already inside the data these models were trained on. It's like they've been to the library and read all the books, but can they actually use the information in a creative, problem-solving way?
What makes FormulaOne so special? Well, a few things:
Real-World Relevance: These aren't just abstract puzzles. They're closely related to problems that companies deal with every day. Think about optimizing delivery routes, scheduling employees, or designing efficient networks. Huge companies spend millions trying to solve these problems!
Automatic Problem Generation: The researchers used a fancy mathematical framework called "Monadic Second-Order (MSO) logic on graphs" (try saying that five times fast!). What's important is that this allows them to create tons of different problems automatically, which is awesome for training AI in the future.
Pushing the Boundaries of Science: Some of these FormulaOne problems are so tough, they're connected to some of the biggest unsolved mysteries in computer science! Solving them could lead to major breakthroughs in our understanding of how computers work.
"Any significant algorithmic progress on our dataset, beyond known results, could carry profound theoretical implications."
Okay, so here's the kicker. These researchers threw FormulaOne at the best AI models we have, including OpenAI's o3, and... they bombed. We're talking less than 1% accuracy, even when given multiple tries and example solutions! It's like giving a master chef a simple recipe and they can't even boil water.
This shows us that even the most advanced AI still have a long way to go before they reach true expert-level understanding, especially when it comes to complex reasoning and problem-solving.
To help researchers make progress, they also created a simpler version of FormulaOne called FormulaOne-Warmup. It's like training wheels for AI, helping them gradually build up their skills. And the best part? They're releasing all the data and tools so anyone can join in and start tinkering!
So, what does this all mean? Well, for the average listener, it's a reminder that AI, while impressive, isn't magic. It has limitations, and we need to be realistic about what it can and can't do. For businesses, it highlights the potential for AI to tackle real-world optimization problems, but also the need for continued research and development. And for scientists, it provides a valuable benchmark for measuring progress in AI reasoning and problem-solving.
Here are a couple of things that popped into my head while reading this:
If these AI models are so good at pattern recognition, why did they struggle so much with FormulaOne? Is it a matter of scale, or is there something fundamentally different about expert-level reasoning?
This research focuses on a very specific domain. How well do these findings generalize to other areas where we expect AI to perform like experts, like medical diagnosis or legal reasoning?
I'm super curious to hear your thoughts on this, learning crew! Let's keep the conversation going. What are your big takeaways from this paper?Credit to Paper authors: Gal Beniamini, Yuval Dor, Alon Vinnikov, Shir Granot Peled, Or Weinstein, Or Sharir, Noam Wies, Tomer Nussbaum, Ido Ben Shaul, Tomer Zekharya, Yoav Levine, Shai Shalev-Shwartz, Amnon Shashua

Machine Learning - Training Transformers with Enforced Lipschitz Constants
Sunday Jul 20, 2025
Sunday Jul 20, 2025
Alright PaperLedge learning crew, Ernis here, ready to dive into some brain-bending research! Today we're tackling a paper about making neural networks, those powerful AI brains, a little less… temperamental. Think of it like this: imagine training a puppy. A well-behaved pup reliably sits when you say "sit." But some neural networks are like super sensitive puppies – a tiny change in your command (the input) or their training (the weights) can make them completely freak out and do something totally unexpected!
This sensitivity causes problems. The paper mentions adversarial examples, which are like optical illusions for AI. You slightly tweak an image, and suddenly the network sees a cat as a dog. There's also divergent training, where the network just goes haywire during learning, and overfitting, where it memorizes the training data instead of learning general rules. Nobody wants that!
So, some researchers have been trying to build neural networks from special "Lipschitz" parts. Think of "Lipschitz" as a guarantee of good behavior. A Lipschitz network promises that small changes in the input will only cause small changes in the output. It's like a volume knob that only goes up a little bit even if you crank it all the way. The problem? These Lipschitz techniques haven’t been good enough to build the really fancy, modern AI models like transformers. Transformers are like the star quarterbacks of AI – they power things like language translation and text generation.
This paper jumps into that gap, trying to build Lipschitz-guaranteed transformers. The first thing they did was create some new, efficient tools for keeping the network's "weight matrices" (basically, how the network connects its neurons) under control. It's like putting a governor on an engine to stop it from over-revving.
Then they trained transformer models with these Lipschitz constraints. And guess what? They found that how you train the network matters a lot! Switching from one type of training method (AdamW) to another (Muon) made a big difference. Muon helped the networks perform just as well, but with a lower "Lipschitz bound" – meaning they were more stable and less likely to freak out.
In fact, the researchers got inspired by Muon, which has a fixed spectral norm (think of it like a measure of the network's "energy"). They designed a new weight constraint method that improved the tradeoff between Lipschitz stability and performance. They even got a 2-Lipschitz transformer (a very stable one!) to reach 60% accuracy on predicting the next word in Shakespearean text. Pretty cool, right?
"We find that optimizer dynamics matter...allowing models to reach equal performance with a lower Lipschitz bound."
They scaled things up to even bigger transformers, using massive amounts of text from the internet. A 10-Lipschitz transformer (still pretty stable) reached 21% accuracy. But here's the kicker: to match the performance of a standard, non-Lipschitz transformer (called NanoGPT), the Lipschitz bound had to go through the roof – like 10 to the power of 264! That’s a HUGE number.
So, what does this all mean? Well, it shows that it's possible to build more stable transformers, but it comes at a cost in terms of performance. The good news is that these Lipschitz transformers don't need all the extra safety features that normal transformers need, like layer norm (stabilizes layer outputs), QK norm (stabilizes attention mechanism), and logit tanh softcapping (constrains output values). It's like building a car with a better suspension – you don't need as many airbags!
Why does this matter? For anyone building AI systems that need to be reliable and predictable – think self-driving cars, medical diagnosis tools, or financial models – this research is crucial. For the average listener, it highlights the ongoing efforts to make AI more trustworthy and less prone to errors.
Here are a couple of things that make me think:
If building a perfectly Lipschitz transformer is so difficult, are there other ways to achieve similar stability, maybe by combining Lipschitz techniques with other methods?
What are the real-world implications of using AI systems that are slightly unstable? Is a small chance of error acceptable in some applications, or should we always strive for perfect stability, even if it means sacrificing performance?
That's all for today, learning crew! Hope you found this dive into Lipschitz transformers as fascinating as I did. Keep learning, and I'll catch you on the next PaperLedge!Credit to Paper authors: Laker Newhouse, R. Preston Hess, Franz Cesista, Andrii Zahorodnii, Jeremy Bernstein, Phillip Isola

Hey Learning Crew, Ernis here, ready to dive into another fascinating piece of research! Today, we're tackling a paper that's all about making realistic videos of people from different angles, even when you don't have a ton of cameras filming them.
Imagine you're watching a concert, and you only have a few recordings from phones scattered around the venue. Wouldn't it be cool to see the performance from any angle, like you're right there on stage or in the VIP section? That's the dream this paper is chasing!
The challenge? It's hard to create new views when you don't have enough information to begin with. The researchers start by using something called a "4D diffusion model." Think of it like a super-smart AI that can fill in the blanks and generate what those missing viewpoints might look like. It's like taking a blurry photo and using AI to sharpen it and add details that weren't there before. However, previous attempts with this approach have a problem: the videos sometimes look a little shaky or inconsistent, like the person is glitching in and out of existence. Not ideal if you're trying for realism.
"The generated videos from these models often lack spatio-temporal consistency, thus degrading view synthesis quality."
So, what's the solution? These researchers came up with a clever trick they call "sliding iterative denoising". Let's break that down:
Denoising: Imagine you have a noisy image, like static on an old TV. Denoising is the process of cleaning up that image, removing the unwanted noise to reveal the clear picture underneath.
Iterative: Instead of cleaning the image just once, they do it repeatedly, refining it each time. Think of it like sculpting – you don't just make one cut, you gradually shape the clay until it's perfect.
Sliding: This is where it gets interesting. They created a virtual "grid" that represents the video. Each point on this grid holds information about the image, camera position, and the person's pose at a specific moment and from a specific angle. They then use a "sliding window" that moves across this grid, cleaning up the data piece by piece. It's like carefully washing a window, moving across it section by section to get every spot.
By sliding this window across both space (different viewpoints) and time (different moments), the model can "borrow" information from nearby points on the grid. This helps ensure that the generated video is consistent and smooth, without any weird glitches. It's kind of like how a good animator makes sure each frame flows seamlessly into the next.
The amazing part? This method allows the AI to see the bigger picture (literally!) without needing a super-powerful computer. By processing the video in smaller chunks with the sliding window, it reduces the amount of memory needed. This means more people can use this technology without needing a super-expensive setup.
They tested their method on two datasets: DNA-Rendering and ActorsHQ. Think of these as benchmarks or testing grounds for this kind of technology. The results? Their method blew the existing approaches out of the water, generating higher-quality, more consistent videos from new viewpoints.
So, why does this matter? Well, imagine the possibilities! This research could revolutionize:
Virtual reality and gaming: Imagine being able to explore a virtual world from any angle, with incredibly realistic characters.
Filmmaking: Creating stunning visual effects and capturing performances from impossible perspectives.
Security and surveillance: Reconstructing events from limited camera footage.
Medical imaging: Creating 3D models of the human body from a limited number of scans.
This research is a significant step forward in creating realistic and immersive experiences. It tackles a complex problem with an innovative solution that's both effective and efficient.
Now, here are a couple of questions that popped into my head while reading this paper:
How far away are we from being able to generate completely photorealistic videos of people from any angle, even with extremely limited input?
Could this technology be used to create deepfakes, and what safeguards need to be in place to prevent misuse?

Alright Learning Crew, Ernis here, ready to dive into some seriously cool video tech! Today, we're unpacking a paper that's all about making Video Large Language Models – think of them as super-smart AI that can watch and understand videos – even better at their jobs.
Now, imagine you're trying to summarize a movie. You wouldn't just randomly pick scenes, right? You'd choose the most important ones, the ones that really tell the story. That's essentially what this research is tackling. The researchers found that the way these Video-LLMs pick out specific frames from a video drastically affects how well they understand the content.
The problem? Existing methods for picking these crucial frames often rely on figuring out what's important without any guidance. It's like asking someone to summarize that movie without telling them what it's about! They might focus on the wrong details.
That's where VideoITG comes in! It stands for Instructed Temporal Grounding for Videos. Think of it as giving the Video-LLM a set of instructions before it starts watching. Instead of wandering aimlessly, it knows what to look for.
The secret sauce behind VideoITG is a system called VidThinker. This system tries to mimic how a human would annotate a video. It's a three-step process:
First, VidThinker generates detailed descriptions of each short clip in the video, based on the instructions.
Then, it uses those descriptions to find the video segments that are most relevant to the instruction.
Finally, it picks out the exact frames within those segments that best represent the key information.
It's like having a super-efficient research assistant that understands exactly what you need and highlights the most important bits. For example, if you asked it to "find scenes with cats playing," it wouldn't just show you random cat videos; it would pinpoint the precise moments where cats are actively playing.
"VideoITG achieves consistent performance improvements across multiple multimodal video understanding benchmarks, showing its superiority and great potentials for video understanding."
To make this work, the researchers created a massive dataset called VideoITG-40K. It's packed with 40,000 videos and half a million annotations, all carefully crafted using VidThinker. This dataset helps train the Video-LLM to understand how to pick the right frames based on instructions.
And the best part? The VideoITG model is designed to be plug-and-play. You can easily add it to existing Video-LLMs to give them a boost. The research shows that VideoITG consistently improves performance across a range of video understanding tasks.
So, why should you care? Well, if you're a:
Researcher: This offers a powerful new way to improve Video-LLMs for all sorts of applications.
Content Creator: Imagine AI that can automatically generate summaries or highlight key moments in your videos!
Educator: This tech could help create more engaging and effective video learning materials.
Everyday Video Watcher: Better Video-LLMs mean more accurate and helpful video search, recommendations, and summaries.
It really is a game changer!
This research opens up some fascinating questions:
Could we use this approach to create personalized video summaries tailored to individual learning styles?
How might VideoITG be used to automatically detect misinformation or bias in videos?
What are the ethical implications of having AI that can so effectively analyze and understand video content?

Hey everyone, Ernis here, and welcome back to PaperLedge! Today, we're diving into some fascinating research about how we judge those super-smart AI language models, you know, like the ones that write emails or answer your random questions online. It's not as simple as just running them through a test, trust me.
So, imagine you're trying to decide which chef makes the best dish. You could give them a multiple-choice test about cooking techniques, right? That's kind of like how we often test these language models – through automated benchmarks. They have to answer a bunch of multiple-choice questions. But here's the problem: how well they do on those tests doesn't always match what real people think. It's like a chef acing the theory but burning every meal!
That's where human evaluation comes in. Instead of a test, you get people to actually taste the food. In the AI world, that means having people read the responses from different language models and decide which one is better. But there are tons of these models now, and getting enough people to evaluate them all in a traditional study would take forever and cost a fortune!
Enter the idea of a "public arena," like the LM Arena. Think of it as a giant online cooking competition where anyone can try the food (responses) and vote for their favorite. People can ask the models any question and then rank the answers from two different models. All those votes get crunched, and you end up with a ranking of the models.
But this paper adds a twist: energy consumption. It's not just about which model gives the best answer, but also how much energy it takes to do it. It's like considering the environmental impact of your food – are those ingredients locally sourced, or did they fly in from across the globe?
The researchers created what they call GEA – the Generative Energy Arena. It's basically the LM Arena, but with energy consumption info displayed alongside the model's responses. So, you can see which model gave a great answer and how much electricity it used to do it.
And guess what? The preliminary results are pretty interesting. It turns out that when people know about the energy cost, they often prefer the smaller, more efficient models! Even if the top-performing model gives a slightly better answer, the extra energy it uses might not be worth it. It's like choosing a delicious, locally grown apple over a slightly sweeter one that was shipped from far away.
“For most user interactions, the extra cost and energy incurred by the more complex and top-performing models do not provide an increase in the perceived quality of the responses that justifies their use.”
So, why does this matter? Well, it's important for a few reasons:
For developers: It suggests they should focus on making models more efficient, not just bigger and more complex.
For users: It highlights that we might be unknowingly contributing to a huge energy footprint by always choosing the "best" (but most power-hungry) AI.
For the planet: It raises awareness about the environmental impact of AI and encourages us to be more mindful of our choices.
This research really makes you think, right? Here are a couple of questions that popped into my head:
If energy consumption was always clearly displayed alongside AI results, would it change how we interact with these models every day?
Could we eventually see "energy-efficient" badges or ratings for AI models, similar to what we have for appliances?
That's all for today's episode! Let me know what you think of the GEA concept. Until next time, keep learning, keep questioning, and keep those energy bills low! Credit to Paper authors: Carlos Arriaga, Gonzalo Martínez, Eneko Sendin, Javier Conde, Pedro Reviriego

Hey PaperLedge crew, Ernis here, ready to dive into some seriously cool AI research! Today, we're tackling a paper about how to make those brainy language models, the kind that can reason and solve problems, even better at thinking things through. Think of it like this: we're trying to train a student to ace a tough math test, not just pass it.
The paper kicks off by pointing out that reinforcement learning, or RL, which is like training an AI with rewards and punishments – a digital carrot and stick – is a popular way to boost these language models. RL is used to train models to improve multi-step reasoning – but recent studies are questioning if RL is really effective on the most difficult problems. It's like trying to teach your dog a super complex trick; sometimes, the usual treats just don't cut it.
So, what's the solution? Well, the researchers propose something called Question Augmentation, or QuestA for short. Imagine you're helping that student with their math homework. Instead of just giving them the problem and saying, "Good luck!", you give them hints, right? Maybe a partial solution, or a step-by-step breakdown. That's essentially what QuestA does. It feeds the language model partial solutions during training to make the problems a little easier and give it more helpful clues along the way.
Think of it like this: If you are training a model to bake a cake, you might give it the first few steps of the recipe completed, or a picture of what the batter should look like.
The result? The researchers found that QuestA significantly improved the language model's ability to solve math problems, not only getting the answer right in the first try (pass@1) but also improving the chances of getting the answer correct after multiple tries (pass@k). This is especially true for those super tricky problems where regular RL struggles.
"Our method, QuestA, when applied during RL training on math reasoning tasks, not only improves pass@1 but also pass@k-particularly on problems where standard RL struggles to make progress."
But here's where it gets really exciting. They used QuestA to train some already powerful open-source language models, and they saw even more improvement. These models, with about 1.5 billion parameters (that's a LOT of brainpower!), achieved state-of-the-art results on challenging math benchmarks. We're talking about significant jumps in accuracy on exams like AIME24, AIME25, and HMMT25.
To give you some stats, they got a 67.1% (+5.3%) on AIME24, 59.5% (+10.0%) on AIME25, and 35.5% (+4.0%) on HMMT25. To put it in perspective, that’s like going from a C to a solid B, or even an A-, just by giving the model a little help during practice!
So, why does this matter?
For AI developers: This provides a practical way to enhance the reasoning abilities of existing language models without drastically increasing their size or complexity. It means we can get more out of the models we already have.
For educators: The concept of providing partial solutions mirrors effective teaching strategies. It reinforces the idea that scaffolding and guidance are crucial for learning complex skills.
For everyone else: As AI becomes more integrated into our lives, improving its reasoning abilities is essential. Better reasoning leads to more accurate and reliable AI systems that can assist us in various tasks, from research to problem-solving.
The paper even delves into the theory behind why QuestA works, suggesting that it improves sample efficiency. This means the model learns faster and more effectively because it's getting more informative signals during training. It's like learning to ride a bike with training wheels first – you gain confidence and balance before tackling the real thing.
So, what are the big takeaways?
QuestA is a simple but powerful technique for improving the reasoning abilities of language models.
It works by providing partial solutions during training, making problems easier to learn.
It leads to significant improvements on challenging math benchmarks.
It offers a practical and generalizable approach for expanding reasoning capabilities through reinforcement learning.
Okay, crew, let’s chew on this a bit...
Could this question augmentation approach be applied to domains other than math, like coding or legal reasoning?
How might we automate the process of generating those helpful "partial solutions" so that it doesn't require manual intervention?
What are the ethical considerations of using AI to solve complex problems, especially if the AI is "guided" towards a particular solution?

Hey PaperLedge learning crew! Ernis here, ready to dive into some fascinating research that could seriously change how we all interact with computers, even if you've never written a line of code in your life.
We're talking about AI Code Assistants, those clever programs that try to write code for you based on what you tell them you want. Think of it like this: you're trying to bake a cake, and instead of knowing the recipe by heart, you just tell a super-smart robot what kind of cake you want, and it whips up the recipe for you. That's the promise of AI code assistants.
But here's the catch: just like that robot chef might accidentally add salt instead of sugar, these AI code assistants often generate code that's... well, wrong. And get this: studies show that people often have a hard time spotting those errors. Imagine accidentally serving your guests a cake made with salt! Not a great experience.
"LLMs often generate incorrect code that users need to fix and the literature suggests users often struggle to detect these errors."
So, how do we make sure our AI chef is actually baking a delicious cake, and not a salty disaster? That's where this paper comes in. These researchers are tackling the problem of trusting AI-generated code. They want to give us formal guarantees that the code actually does what we asked it to do. This is huge, because it could open up programming to everyone, even people with zero coding experience.
Their idea is super clever. They propose using a special kind of language – a formal query language – that lets you describe exactly what you want the code to do, but in a way that's still pretty natural and easy to understand. Think of it like giving the robot chef a very, very specific set of instructions, like "Add exactly 1 cup of sugar, and absolutely no salt!".
Then, the system checks the code the AI assistant generates against those super-specific instructions. It's like having a food inspector double-checking the robot chef's work to make sure it followed the recipe to the letter.
They've built a system called Astrogator to test this out, focusing on a programming language called Ansible. Ansible is used to automate computer system administration. They created a calculus for representing the behavior of Ansible programs and a symbolic interpreter which is used for the verification.
Here's the really cool part: when they tested Astrogator on a bunch of code-generation tasks, it was able to verify correct code 83% of the time and identify incorrect code 92% of the time! That's a massive improvement in trust and reliability.
So, why does this matter to you, the PaperLedge listener?
For the seasoned programmers: This could dramatically speed up your workflow by catching errors early and boosting your confidence in AI-generated code.
For the aspiring programmers: This could lower the barrier to entry, making coding more accessible and intuitive.
For everyone else: This is a step towards a future where interacting with technology is as simple as describing what you want in plain language, without needing to be a technical expert.
This research raises some really interesting questions:
How easy will it really be for non-programmers to use this formal query language? Will it feel natural and intuitive, or will it still require some technical knowledge?
Could this approach be applied to other programming languages beyond Ansible? What are the challenges in adapting it to more complex or less structured languages?
As AI code assistants become more powerful, will we eventually reach a point where we can completely trust them to write perfect code, making formal verification unnecessary? Or will verification always be a crucial safety net?
I'm excited to see where this research leads us! What are your thoughts, crew? Let me know in the comments!Credit to Paper authors: Aaron Councilman, David Fu, Aryan Gupta, Chengxiao Wang, David Grove, Yu-Xiong Wang, Vikram Adve

Alright learning crew, Ernis here, ready to dive into some cutting-edge research! Today, we’re talking about keeping AI safe, specifically those super-smart AIs that can understand both words and images - what we call Multimodal Large Language Models, or MLLMs for short.
Think of it like this: imagine you're teaching a child to recognize a "bad" thing, like a hot stove. You show them pictures, tell them stories, and explain why touching it is dangerous. Now, imagine someone tries to trick the child, maybe by making the stove look like a toy. That's kind of what "adversarial multimodal inputs" are doing to these MLLMs – trying to fool them into doing something unsafe!
These MLLMs are becoming incredibly powerful, but with great power comes great responsibility, right? The researchers behind this paper were concerned about these “attacks” and wanted to find a way to make these AIs safer without having to constantly retrain them from scratch.
Their solution is called AutoSteer, and it's like giving the AI a built-in safety mechanism that kicks in during use – at inference time. Think of it as adding a smart "filter" to their thinking process. Instead of retraining the whole AI, they focus on intervening only when things get risky.
AutoSteer has three main parts:
Safety Awareness Score (SAS): This is like the AI's inner sense of danger. It figures out which parts of the AI's "brain" are most sensitive to safety issues. It's like knowing which friend gives the best advice when you're facing a tough decision.
Adaptive Safety Prober: This part is like a lie detector. It looks at the AI's thought process and tries to predict if it's about to say or do something harmful. It’s trained to spot those red flags!
Refusal Head: This is the actual intervention part. If the "lie detector" senses danger, the Refusal Head steps in and gently nudges the AI in a safer direction. It might subtly change the wording or even refuse to answer a dangerous question.
The researchers tested AutoSteer on some popular MLLMs like LLaVA-OV and Chameleon, using tricky situations designed to fool the AI. They found that AutoSteer significantly reduced the Attack Success Rate (ASR) – meaning it was much harder to trick the AI into doing something unsafe, whether the threat came from text, images, or a combination of both.
Here’s a key takeaway:
AutoSteer acts as a practical, understandable, and effective way to make multimodal AI systems safer in the real world.
So, why does this matter to you?
For the everyday user: Safer AI means less chance of encountering harmful content, biased information, or being manipulated by AI-powered scams.
For developers: AutoSteer provides a practical way to build safer AI systems without the huge cost of retraining models from scratch.
For policymakers: This research offers a potential framework for regulating AI safety and ensuring responsible development.
This research is a big step towards building AI that’s not only powerful but also trustworthy and aligned with human values.
Now, some questions to ponder:
Could AutoSteer, or systems like it, be used to censor AI or push certain agendas? How do we ensure fairness and transparency in these interventions?
As AI gets even more sophisticated, will these "attackers" always be one step ahead? How do we create safety mechanisms that can adapt to new and unforeseen threats?
What are the ethical implications of "nudging" an AI's responses? At what point does intervention become manipulation?
That's all for today, learning crew! Keep those brains buzzing, and I'll catch you next time for more insights from the world of research!Credit to Paper authors: Lyucheng Wu, Mengru Wang, Ziwen Xu, Tri Cao, Nay Oo, Bryan Hooi, Shumin Deng
