Hey PaperLedge crew, Ernis here, ready to dive into some seriously cool research! Today, we're tackling a paper that asks a fundamental question: How can we make AI think more like us?
See, humans are amazing at problem-solving because we use all sorts of tools in our mental toolkit. We might describe the problem in simple words (natural language), sketch out a plan (like pseudo-code), or even use logic and symbols to break it down. But most AI, especially those big language models, only stick to one tool – usually just natural language. It's like trying to build a house with only a hammer!
This research introduces a framework called Mixture-of-Thought (MoT). Think of it as giving AI that full toolkit, teaching it to reason using not just natural language, but also code and something brand new: truth tables.
What's a truth table? Imagine you're trying to figure out if a statement like "If it rains, the ground gets wet" is true. A truth table systematically checks all the possibilities: rain and wet ground, rain and dry ground, no rain and wet ground, no rain and dry ground. It's a super precise way to analyze logical situations.
The researchers trained their AI in two phases:
Phase 1: Self-Evolving MoT Training. The AI basically teaches itself, generating its own reasoning steps in language, code, and truth tables. It then filters out the bad reasoning and learns from the good stuff. Think of it like practicing a sport – you make mistakes, learn from them, and get better over time.
Phase 2: MoT Inference. Now, when faced with a new problem, the AI uses all three reasoning methods together to find the best answer. It's like having a team of experts, each with their own unique skills, working together to solve a puzzle.
So, why is this a big deal? Well, the researchers tested MoT on tough logical reasoning problems, like those found in FOLIO and ProofWriter, and it significantly outperformed AI that only used natural language. We're talking about an accuracy boost of up to 11.7%! That's huge!
The results showed that MoT isn't just better; it's better because each reasoning method brings something unique to the table. Truth tables, in particular, helped overcome some of the common errors that language models make when reasoning. Think of it like this: natural language might be good for explaining the why, but truth tables are great for proving the what.
So, what does this mean for us, the PaperLedge listeners?
For AI researchers: This shows the power of multi-modal reasoning and offers a new approach to training more robust and accurate AI systems.
For developers: This could lead to AI-powered tools that are better at understanding and solving complex problems, from debugging code to making critical decisions.
For everyone else: This research brings us closer to AI that can reason more like humans, potentially leading to more reliable and helpful AI assistants in the future.
But it also raises some interesting questions:
Could we expand this "Mixture-of-Thought" approach to include even more reasoning modalities? What about visual reasoning, for example?
How do we ensure that AI using these different modalities doesn't introduce new biases or perpetuate existing ones?
If AI can reason more effectively using multiple modalities, how will that change the way we teach and learn? Will we need to focus more on developing these different reasoning skills in ourselves?
Food for thought, right? That's all for this episode. Keep learning, everyone!Credit to Paper authors: Tong Zheng, Lichang Chen, Simeng Han, R. Thomas McCoy, Heng Huang

Computer Vision - MMaDA Multimodal Large Diffusion Language Models
Thursday May 22, 2025
Thursday May 22, 2025
Hey PaperLedge learning crew, Ernis here, ready to dive into some seriously cool AI research!
Today, we're talking about MMaDA, which sounds like a futuristic dance move, but it's actually a groundbreaking new type of AI model. Think of it as the Swiss Army knife of AI – it's designed to be amazing at all sorts of things, from understanding text and images to even creating images from text!
So, what makes MMaDA so special? Well, traditionally, if you wanted an AI to be good at, say, both understanding written instructions and creating images, you'd need two separate AI models. It's like having a translator who only speaks English and an artist who only understands French – they're not going to collaborate very well.
MMaDA changes all that by using a unified diffusion architecture. That's a fancy way of saying it uses the same core engine, the same underlying "brain," to process different types of information. Imagine a universal translator that understands any language and can translate it into any other language – that's the power of a unified architecture.
The researchers achieved this by:
Making it modality-agnostic: This basically means that the AI doesn't care what type of data it's dealing with. Whether it's text, an image, or even audio, it can handle it all with the same set of tools.
Using a shared probabilistic formulation: Think of this like a common language that all the different data types can be translated into. This allows the AI to seamlessly integrate and process everything.
But it doesn't stop there! MMaDA also uses a clever strategy called mixed long chain-of-thought (CoT) fine-tuning. Now, that's a mouthful! But here's the gist: CoT is like showing the AI how to think step-by-step through a problem. With mixed CoT, the researchers created a single, unified way of teaching MMaDA to reason, whether it's reasoning about text or images. This is like teaching our translator and artist to think the same way, so they can work together more effectively.
Think of it as giving the AI a detailed instruction manual showing it exactly how to think through problems, whether they're written, visual, or something else entirely.
This helps MMaDA to hit the ground running during the final stage of its training, which involves something called reinforcement learning (RL). RL is like training a dog with rewards and punishments. The AI learns what works and what doesn't by getting positive or negative feedback on its actions.
Finally, the researchers developed UniGRPO, a special reinforcement learning algorithm specifically designed for diffusion models like MMaDA. This algorithm uses diversified reward modeling to provide consistent improvements across both reasoning and generation tasks. It's like having a super-effective training program that guarantees your dog learns all the tricks!
So, MMaDA uses UniGRPO to fine-tune it's AI super powers in a way that makes it a well-rounded, high-performing model.
The results? They're pretty impressive. The researchers found that MMaDA-8B (that's the 8 billion parameter version) outperformed other powerful models in a variety of tasks:
It was better at textual reasoning than models like LLaMA-3-7B and Qwen2-7B.
It was better at multimodal understanding than models like Show-o and SEED-X.
And it was better at text-to-image generation than models like SDXL and Janus!
Basically, MMaDA is a superstar across the board!
Why does this matter? Well, imagine a future where AI can seamlessly understand and interact with the world around us, regardless of the format of the information. This could revolutionize everything from education and healthcare to entertainment and art.
For example:
For educators: Imagine AI tutors that can explain complex concepts using both text and visuals, perfectly tailored to each student's learning style.
For artists: Imagine AI tools that can bring your wildest creative visions to life, generating stunning visuals from simple text descriptions.
For everyone: Imagine AI assistants that can understand your needs and provide helpful support, whether you're asking a question, solving a problem, or just looking for information.
The researchers have even open-sourced their code and trained models, so other researchers can build on their work. It's all available at the link in the description.
This research is a big step forward in creating more versatile and powerful AI systems. But it also raises some interesting questions:
As AI models become more capable of understanding and generating different types of content, how do we ensure they're used ethically and responsibly?
Could unified multimodal models like MMaDA eventually replace the need for specialized AI systems, or will there always be a place for models that are optimized for specific tasks?
What are the potential risks and benefits of AI that can seamlessly process and integrate information from different modalities, and how can we prepare for them?

Hey PaperLedge learning crew, Ernis here, ready to dive into some seriously cool research! Today, we're talking about language, AI, and building tools that work for everyone, not just those who speak English.
So, you know how we've been seeing these amazing AI agents that can book flights, order groceries, and even write emails for us? Well, most of them are trained primarily on English. Think of it like this: imagine you're a super-skilled chef, but you only know how to cook Italian food. You'd be amazing at pasta and pizza, but what about sushi, tacos, or injera? That's kind of where we're at with these AI agents and other languages.
That's where this paper comes in. These researchers recognized that the world speaks way more than just English – over 7,000 languages, in fact! And everyone deserves to have access to these helpful AI tools, right?
To tackle this, they created something called X-WebAgentBench. Now, that's a mouthful, but basically, it's a new way to test how well AI agents can understand and interact with websites in different languages. Think of it as a multilingual obstacle course for AI! It checks if they can plan and complete tasks on websites in various languages.
Why is this important? Well, imagine you're traveling in Spain and need to book a train ticket online. If the website is only in Spanish, and your AI assistant only speaks English, you're out of luck. X-WebAgentBench helps researchers build AI that can handle these real-world scenarios.
"We hope that X-WebAgentBench can serve as a valuable benchmark for multilingual agent scenario in real-world applications."
Now, the researchers didn't just create the benchmark; they also put some of the best AI models to the test, including the super-powerful GPT-4o. They even tried using techniques to help the AI "translate" its understanding from English to other languages. But guess what? Even with all that, the AI still struggled to perform well across all languages.
This is a bit like trying to teach someone to ride a bike by only showing them videos and giving them instructions in a language they don't understand. They might get the basic idea, but they're going to have a hard time actually staying upright!
The results showed that there's still a long way to go before AI agents can truly understand and interact with the web in a multitude of languages.
So, why should you care about this research? Well, if you're a:
Tech enthusiast: This shows us the current limitations of even the most advanced AI and highlights an area ripe for innovation.
Language learner: Imagine having an AI assistant that can help you navigate websites and access information in your target language.
Global citizen: This is about making technology more inclusive and accessible to everyone, regardless of their language.
This research highlights the need for more work in multilingual AI. It's not just about translating words; it's about understanding the nuances of different languages and cultures to build truly helpful and accessible AI agents.
What do you all think? Does this highlight the importance of diverse training data for AI? And how might this impact future language learning technology?Credit to Paper authors: Peng Wang, Ruihan Tao, Qiguang Chen, Mengkang Hu, Libo Qin

Alright learning crew, Ernis here, ready to dive into another fascinating paper! Today, we're unpacking some cutting-edge research on how we can make AI models really good at understanding images, especially when they need to think critically about what they're seeing.
The paper focuses on Vision Language Models, or VLMs. Think of these as AI brains that can "see" like us, and "talk" like us. They're getting really good at things like identifying objects in pictures, or even describing what's happening in a scene. But, just like us, sometimes they need to focus to really understand what's going on.
This research tackles the problem that while VLMs are impressive, their reasoning skills – their ability to analyze and draw conclusions from visual information – still have room for improvement. Imagine trying to solve a puzzle where you can see all the pieces, but you're not quite sure how they fit together. That's kind of where current VLMs are at.
So, what's the solution? The researchers introduce a clever new method called Chain-of-Focus (CoF). The best way to think of it is like a detective carefully examining a crime scene. Instead of looking at everything at once, the VLM adaptively zooms in on the most important areas, based on both the image itself and the question it's trying to answer.
Imagine you're looking at a picture of a crowded market and someone asks, "What's the price of the red apples?" You wouldn't analyze every single person or stall; you'd quickly narrow your focus to the fruit stands, and then specifically the red apples. CoF helps VLMs do exactly that.
This "focusing and zooming" isn't random; it's a chain of actions, each one building on the previous. It's like reading a book – you understand each sentence in relation to the sentences before it, gradually building a complete understanding of the story.
Now, how did they teach the VLM to do this fancy focusing trick? They used a two-step training process:
Step 1: Supervised Fine-Tuning (SFT). They created a special dataset called MM-CoF, which is like a training manual for visual reasoning. It contains 3,000 examples of images and questions, along with instructions on where to focus in the image to find the answer. They used this to give the VLM (specifically, the Qwen2.5-VL model) a "cold start," like teaching it the basics of how to look at images strategically.
Step 2: Reinforcement Learning (RL). This is where things get really interesting. The VLM is essentially given rewards for getting the right answers and following the correct "focusing" steps. This allows it to refine its reasoning strategy without being explicitly told what to do. It's like training a dog with treats – it learns to perform the desired behavior based on positive reinforcement.
So, what were the results? The researchers found that their CoF method significantly improved the VLM's performance on visual reasoning tasks. In fact, on a challenging benchmark called V, their model outperformed existing VLMs by a whopping 5% across different image resolutions, even up to super high-definition 4K images!
This is a big deal because it shows that CoF is not only effective but also efficient. The VLM doesn't need to process the entire image at once; it can strategically focus on the relevant parts, saving computational resources and making it more practical for real-world applications.
Why does this matter?
For AI developers: This research provides a valuable technique for improving the reasoning capabilities of VLMs, leading to more sophisticated and reliable AI systems.
For businesses: More accurate VLMs can be used in a variety of applications, such as automated quality control, image-based search, and even medical image analysis.
For everyone: Ultimately, this research contributes to the development of AI that can better understand and interact with the world around us.
So, learning crew, that's the Chain-of-Focus in a nutshell! It's a powerful technique that helps VLMs think more like us when it comes to visual reasoning. Now, I'm curious to hear your thoughts.
Here are a couple of questions that popped into my head:
Do you think this "Chain-of-Focus" approach could be applied to other areas of AI, like natural language processing, where focusing on key words or phrases is crucial?
As VLMs become more sophisticated, what ethical considerations should we be mindful of, especially regarding privacy and potential biases in image recognition?

Alright learning crew, gather ‘round! Today on PaperLedge, we're diving into some seriously cool tech that could revolutionize how doctors perform endoscopies. You know, those procedures where they stick a tiny camera down your throat or, well, other places, to check things out?
Imagine a self-driving car, but instead of navigating roads, it's navigating the twists and turns of the human body. That's kind of what we're talking about here.
Traditionally, these procedures rely heavily on the doctor's skill and focus. They have to spot the abnormalities, guide the scope, and sometimes even perform precise maneuvers, like marking areas for removal. It's a lot to handle, and frankly, it can be tiring and prone to human error.
This paper explores a new approach using something called a Vision-Language-Action (VLA) model, or EndoVLA as the researchers call it. Think of it as giving the endoscope a brain that understands both what it sees (the images from the camera) and what the doctor tells it to do using simple prompts. It’s like having a super-smart assistant that knows exactly what you want just from a few words.
So, instead of the doctor having to manually control every tiny movement, they can say something like, "Track that polyp," and the EndoVLA system will automatically follow it, keeping it centered in the camera's view. Or, if they need to cut around a suspicious area, they can instruct the system to "Follow the circular marker," and it will precisely trace the designated path.
The researchers trained this system to do three key things:
Track polyps (those potentially cancerous growths)
Outline and follow abnormal areas in the lining of the gut
Stick to circular markers for precise cutting
Now, building a system like this isn't easy. The inside of the human body is a messy, unpredictable place. It's not like a perfectly lit and labeled dataset. That's where the really clever part comes in.
One of the big challenges is data scarcity. There just aren't that many labeled images of endoscopic procedures available to train a model on. To overcome this, the researchers used a two-step training process:
Supervised fine-tuning: First, they trained the system on a dataset they created called EndoVLA-Motion.
Reinforcement fine-tuning: Then, they used reinforcement learning, rewarding the system when it successfully completed tasks. Think of it like training a dog with treats – the system learns what works best through trial and error.
This dual-phase strategy allowed the system to learn effectively even with limited data and adapt to different scenarios. They were able to get the system to perform well in scenarios it has never seen before, they call that zero-shot generalization.
Why does this matter? Well, for doctors, it could mean reduced fatigue, improved accuracy, and the ability to focus on more complex aspects of the procedure. For patients, it could translate to faster procedures, lower risk of complications, and ultimately, better outcomes. Imagine a surgeon who can spend more time analyzing the tissue and making critical decisions, instead of wrestling with the controls. It could allow more doctors and medical staff to work in rural or underserved areas since it can reduce the stress of these procedures.
This research is a big step towards making endoscopic procedures safer, more efficient, and more accessible. It's a fantastic example of how AI can be used to augment human capabilities and improve healthcare for everyone.
But it also raises some interesting questions:
How do we ensure that these AI systems are truly unbiased and don't perpetuate existing healthcare disparities?
What level of autonomy is appropriate in these procedures? How do we balance the benefits of automation with the need for human oversight and control?
How can we ensure that doctors are properly trained to use these systems and that they maintain their core skills even as AI takes on more of the burden?
These are just some of the things we need to think about as we move towards a future where AI plays a bigger role in medicine. What do you think, learning crew?

Hey learning crew, Ernis here, ready to dive into something seriously cool! Today we're talking about how well AI, specifically these giant language models that can also see (we call them Multimodal Large Language Models, or MLLMs), can actually understand physics.
Now, you might be thinking, "AI does everything these days, what's the big deal?" Well, physics is a different beast. It's not just about memorizing facts; it's about understanding how the world works, from why an apple falls to how a rocket launches. It requires understanding relationships, predicting outcomes, and even visualizing scenarios.
Think of it like this: imagine teaching a robot to bake a cake. It's not enough to just give it the recipe. It needs to understand what "creaming butter and sugar" means, how the ingredients interact, and what the final result should look like. Physics is the same – it's about understanding the underlying principles.
This new research paper introduces something called PhysicsArena. Think of it as a super-challenging obstacle course designed to test these MLLMs on their physics smarts. The researchers realized that current tests are... well, a little basic. They usually just focus on one aspect, like solving a numerical problem, or only use text as input. That's like testing a chef only on their ability to read a recipe, not actually cook!
PhysicsArena, on the other hand, throws everything at the AI. It tests three key skills:
Variable Identification: Can the AI figure out what's important in a given scenario? Imagine looking at a picture of a swing set. Can the AI identify the length of the chain, the weight of the person swinging, and the angle of the swing as important factors?
Physical Process Formulation: Can the AI explain what's happening using physics principles? So, instead of just seeing a swing moving, can it explain that it's oscillating due to gravity and inertia?
Solution Derivation: And, of course, can the AI actually solve the problem? Can it predict how high the swing will go or how long it will take to complete one swing?
The cool thing about PhysicsArena is that it uses multimodal information. That means the AI gets to see pictures, diagrams, and text, just like we do when we're learning about physics. This is crucial because real-world physics problems aren't just presented as equations; they're often visual and contextual.
"PhysicsArena aims to provide a comprehensive platform for assessing and advancing the multimodal physics reasoning abilities of MLLMs."
So, why does this research matter? Well, imagine AI tutors that can actually understand the physics concepts they're teaching, not just regurgitate formulas. Imagine robots that can troubleshoot complex mechanical systems or design new materials with specific properties. The possibilities are huge!
For educators, this means the potential for personalized learning experiences that adapt to each student's understanding. For engineers and scientists, it means powerful tools for simulation and design. And for anyone curious about the world around them, it means AI that can help us unlock the mysteries of the universe.
But it also brings up some interesting questions, right?
If an AI can solve physics problems, does it truly understand physics, or is it just really good at pattern recognition?
How can we ensure that AI is used ethically in physics-related applications, especially when it comes to safety-critical systems?
Really interesting food for thought as we continue to explore the intersection of AI and our understanding of the universe.Credit to Paper authors: Song Dai, Yibo Yan, Jiamin Su, Dongfang Zihao, Yubo Gao, Yonghua Hei, Jungang Li, Junyan Zhang, Sicheng Tao, Zhuoran Gao, Xuming Hu

Alright learning crew, Ernis here, ready to dive into some cutting-edge research! Today, we're talking about how well AI can actually see and understand the world around it, and I mean really understand it, not just parrot back information.
We're looking at a paper that tackles a big problem: even though AI models called Multimodal Large Language Models (MLLMs) are getting super good at combining images and words, they still struggle with complex, real-world situations. Think of it like this: you can teach a kid to identify all the ingredients in a cake, but can they then figure out why the cake didn't rise? That's the kind of reasoning we're talking about.
The researchers behind this paper noticed that current tests for these AI models are often too simple. They're like giving the AI a bunch of separate, unrelated tasks, instead of seeing if it can use its "eyes" and "brain" together to solve a bigger problem. To fix this, they created something called Lens.
Lens is basically a super-detailed, multi-level benchmark. Imagine it as a curriculum with three levels:
Perception: Can the AI simply see what's in the image? Can it identify objects and people? This is like the AI learning its ABCs.
Understanding: Can the AI understand the relationships between those objects? Who is doing what? Where is it happening? This is where the AI starts forming words and sentences.
Reasoning: Can the AI draw conclusions and make inferences about the scene? Why is this person sad? What might happen next? This is the AI writing a whole story!
What makes Lens special is that it's built around real-world scenarios. They've collected over 3,400 images from social media, many of which are dated after January 2025 (meaning they're trying to stay ahead of the curve!). And for each image, they've created over 60,000 questions designed to test the AI at all three levels: perception, understanding, and reasoning. The really cool part is that all the questions for a single image are designed to be interconnected, so the AI has to use what it learns in the "perception" stage to help it with the "reasoning" stage.
"This dataset intrinsically supports to evaluate MLLMs to handle image-invariable prompts, from basic perception to compositional reasoning."
So, what did they find? Well, they tested a bunch of top-of-the-line MLLMs, including some seriously powerful ones like Qwen2.5-VL-72B and GPT-4o. And guess what? Even the best models struggled with the reasoning tasks, with none achieving more than 60% accuracy. This shows there's still a long way to go before AI can truly understand and reason about the world like we do.
Why does this matter? Well, think about it: if we want AI to help us with complex tasks like self-driving cars, medical diagnosis, or even just helping us navigate our daily lives, it needs to be able to reason about what it sees. Lens helps us measure how far we have to go and gives researchers a tool to build better, more intelligent AI.
This research matters to:
AI Researchers: They get a new, challenging benchmark to push the limits of MLLMs.
Developers: They can use the insights from Lens to build AI systems that are more reliable and trustworthy.
Everyone Else: Ultimately, this research helps create AI that can better understand and assist us in our daily lives.
This paper really got me thinking. Here are a couple of questions that popped into my head:
If these models are struggling with reasoning in relatively simple, everyday scenarios, how can we trust them to make high-stakes decisions in areas like healthcare or finance?
Could the way we're training these models be part of the problem? Are we focusing too much on pattern recognition and not enough on teaching them how to think critically?

Hey PaperLedge learning crew, Ernis here, ready to dive into something super cool that could change how we build really reliable software and systems. Think things like airplane controls, medical devices, or even the blockchain – stuff where a tiny mistake could have HUGE consequences.
Today, we're unpacking a paper about using AI, specifically large language models – the same tech that powers a lot of chatbots – to help us with something called formal methods.
Now, formal methods might sound intimidating, but at its heart, it's all about using math to prove that a system works correctly. It's like having an ironclad guarantee that your code does exactly what it's supposed to do. The problem? Traditionally, it's been incredibly time-consuming and requires experts who can wrestle with complex mathematical proofs. Imagine trying to solve a giant Sudoku puzzle, but instead of numbers, you have code and logic!
That's where this research comes in. The authors are tackling the challenge of automating this proof process using AI. It's like teaching a computer to solve those Sudoku puzzles for us, freeing up human experts to focus on the bigger picture.
The traditional approach involves two techniques:
Tactic-based generation: Think of this as building the proof step-by-step, using specific "tactics" or strategies. It’s meticulous and precise, like carefully constructing a Lego castle brick by brick.
Whole-proof synthesis: This is like trying to guess the entire solution at once. It’s faster, but also riskier, like trying to build that Lego castle from a single, wild idea.
What's so innovative about this paper is that it does not settle for one. It combines the two techniques. They've created a system called HybridProver, a "dual-model" approach that takes the best of both worlds! Their system first attempts to generate the whole proof at once. Then, it extracts the critical steps from the proof and uses the tactic-based generation method to fill in the gaps and verify everything.
Think of it like this: imagine you're writing an essay. Whole-proof generation is like writing a rough draft to get your ideas down. Tactic-based generation is like carefully editing and refining each sentence to make sure your arguments are airtight.
"HybridProver combines whole-proof and tactic-based generation to harness the benefits of both approaches."
To test their system, the researchers used a theorem prover called Isabelle and a dataset called miniF2F. Think of Isabelle as the software used to check the math, and miniF2F as a set of challenging problems to solve. The results were impressive! HybridProver achieved a 59.4% success rate on the miniF2F dataset, surpassing the previous state-of-the-art which was 56.1%. Their experiments showed that combining both approaches lead to the boost in accuracy.
They also open-sourced their code, datasets, and even the AI models themselves. This is a huge deal for the research community, allowing others to build on their work and accelerate progress in this field.
So, why should you care about this research?
For developers: This could lead to tools that help you write more reliable code, reducing bugs and improving the quality of your software.
For researchers: It opens up new avenues for exploring how AI can assist in formal verification, pushing the boundaries of automated theorem proving.
For everyone: Ultimately, this research contributes to building more trustworthy and dependable systems that we all rely on every day.
This work also highlights the importance of high-quality training data and careful tuning of the AI models. It's a reminder that AI is not a magic bullet, but a tool that requires careful design and implementation.
Here are a few things I'm wondering about:
How far away are we from seeing these AI-powered proof assistants integrated into real-world software development workflows?
Could this approach be adapted to other theorem provers or programming languages?
What are the ethical considerations of relying on AI to verify the correctness of critical systems?
That's all for this episode! Hope you found that as fascinating as I did. Until next time, keep learning, keep questioning, and keep building!Credit to Paper authors: Jilin Hu, Jianyu Zhang, Yongwang Zhao, Talia Ringer
