In the world of artificial intelligence, reasoning is a bit like the secret sauce that makes everything work. This is especially true when we talk about solving puzzles, like Raven's Progressive Matrices (RPM). These puzzles require a mix of logic and math, making them a real challenge for machines. Recently, researchers took a closer look at how well large language models (LLMs), like GPT-4, stack up against a different kind of approach called neuro-symbolic reasoning. Spoiler alert: the results are pretty interesting!
What Are Raven's Progressive Matrices?
Raven's Progressive Matrices are like a series of mind games that test how well someone can understand Patterns and relationships between shapes. Imagine a series of boxes filled with unique patterns, and one box is missing. The task? Figure out which pattern fits best in the empty box. These puzzles are designed to measure fluid intelligence, which is how people use logic and reasoning to solve unfamiliar problems.
The Challenge for AI
While humans might find these puzzles manageable, they can be tricky for AI. Traditional models like LLMs rely on massive amounts of text to learn. When faced with visual puzzles like RPM, they have to translate the visual elements into language, which isn’t always smooth sailing. This research sought to uncover just how well these models can handle such tasks, especially regarding mathematical reasoning.
The Great AI Showdown
In this study, researchers decided to host a showdown between two different AI methods: LLMs and Neuro-symbolic Systems. LLMs are like the know-it-alls of AI, trained on a bunch of text and capable of generating sentences that make sense. On the other hand, neuro-symbolic systems are designed to handle structured data and relationships, making them a potentially better fit for reasoning tasks.
The Set-Up: Testing the Models
To compare the two AI methods, researchers created tests using Raven's Progressive Matrices. They presented these models with various visual puzzles and measured how well they could solve them. The idea was to see if one approach outshined the other or if they both struggled in the face of abstract reasoning.
The Results: Who’s the Cleverest AI?
The tests revealed that LLMs like GPT-4 and Llama-3 had some serious issues when it came to understanding and applying Arithmetic rules. Even when given clear guidelines and organized data, they found it difficult to get the right answers in RPM. For example, in one specific set of tests called the center constellation of I-RAVEN, LLMs were surprisingly inaccurate.
In stark contrast, neuro-symbolic models showed a knack for recognizing patterns and applying arithmetic rules effectively. They scored remarkably high, almost nailing the correct answers across the board. So, in this battle of the AIs, it seemed that the neuro-symbolic approach took the crown for reasoning tasks.
The Arithmetic Struggle
A big part of the problem for LLMs lay in their handling of arithmetic rules. While they could process complex text and language-based tasks, when it came to number-crunching and logical deductions, they stumbled. It’s like asking a math whiz to paint a masterpiece—it just doesn’t add up!
Expanding the Challenge
To make things even more interesting, researchers decided to ramp up the difficulty. They expanded the RPM puzzles to larger sizes, creating grids that were wider and allowed for higher ranges of numbers. This was a particularly tough challenge for LLMs, and the results were eye-opening. As the size of the grids and the range of numbers grew, the accuracy of LLMs plummeted to less than 10% for arithmetic problems. Meanwhile, the neuro-symbolic systems maintained their stellar performance.
Why Are LLMs Struggling?
So, what’s causing all this trouble for LLMs? The researchers speculated that many LLMs rely heavily on surface-level pattern recognition, which can lead to short-lived reasoning. Instead of digging deep into what the rules are, they tend to look at the last row of a puzzle and guess the answer based on a few clues. This sort of reasoning might work for simpler problems, but when the puzzles get tough, it falls short.
Making Sense of the Results
The findings from this research shine a light on the different strengths and weaknesses of LLMs and neuro-symbolic approaches. LLMs may excel in tasks where language and context are key, but when faced with structured reasoning and arithmetic logic, they can falter. Neuro-symbolic systems, with their ability to process complex relationships and patterns, emerged as the more reliable choice for these types of reasoning tasks.
The Future of AI Reasoning
With the results in hand, there’s hope that understanding the strengths of neuro-symbolic systems can help improve LLMs. It’s like a team of superheroes combining their forces to create an even more powerful entity! By integrating the structured reasoning capabilities of neuro-symbolic approaches into LLMs, we may find a path toward machines that can tackle complex reasoning with greater success.
Conclusion
The quest for better AI reasoning continues. As researchers uncover more about how different models perform, we inch closer to creating machines that can reason and think in ways similar to humans. In the world of AI, it’s not just about being able to generate text or process data; it’s about learning to reason, solve puzzles, and navigate the complexities of the world. And who knows? Maybe one day, we’ll have AIs that can outsmart us at our own games!
Keep your thinking caps on—after all, in the race of brains (or circuits), there’s always more to learn and discover!

Title: Towards Learning to Reason: Comparing LLMs with Neuro-Symbolic on Arithmetic Relations in Abstract Reasoning
Abstract: This work compares large language models (LLMs) and neuro-symbolic approaches in solving Raven's progressive matrices (RPM), a visual abstract reasoning test that involves the understanding of mathematical rules such as progression or arithmetic addition. Providing the visual attributes directly as textual prompts, which assumes an oracle visual perception module, allows us to measure the model's abstract reasoning capability in isolation. Despite providing such compositionally structured representations from the oracle visual perception and advanced prompting techniques, both GPT-4 and Llama-3 70B cannot achieve perfect accuracy on the center constellation of the I-RAVEN dataset. Our analysis reveals that the root cause lies in the LLM's weakness in understanding and executing arithmetic rules. As a potential remedy, we analyze the Abductive Rule Learner with Context-awareness (ARLC), a neuro-symbolic approach that learns to reason with vector-symbolic architectures (VSAs). Here, concepts are represented with distributed vectors s.t. dot products between encoded vectors define a similarity kernel, and simple element-wise operations on the vectors perform addition/subtraction on the encoded values. We find that ARLC achieves almost perfect accuracy on the center constellation of I-RAVEN, demonstrating a high fidelity in arithmetic rules. To stress the length generalization capabilities of the models, we extend the RPM tests to larger matrices (3x10 instead of typical 3x3) and larger dynamic ranges of the attribute values (from 10 up to 1000). We find that the LLM's accuracy of solving arithmetic rules drops to sub-10%, especially as the dynamic range expands, while ARLC can maintain a high accuracy due to emulating symbolic computations on top of properly distributed representations.
