On Memorization of Large Language Models in Logical Reasoning
Google; University of Illinois Urbana-Champaign; Princeton University; Allen Institute for AI
This paper delves into the memorization habits of large language models when tackling logical reasoning tasks, highlighting their reliance on memorized knowledge when tested with familiar puzzles. The research underscores that LLMs falter when faced with even slight changes to these puzzles, suggesting a heavy dependence on rote learning over genuine reasoning. Interestingly, the study also uncovers that while fine-tuning tends to boost generalization, it doesn’t entirely eradicate the tendency to memorize, indicating a nuanced interplay between memorization and reasoning.
Raw notes: It’s a fine line between rote memorization and deep understanding when it comes to LLMs. We still don’t know much about how they work.
Can Language Models Replace Programmers? REPOCOD Says ‘Not Yet’
Purdue University
This paper evaluates the effectiveness of large language models in code generation using the REPOCOD benchmark, derived from real-world projects, and reveals that none of the tested models surpass a 30% success rate. While traditionally Claude Sonnet 3.5 has been perceived as the leader in code generation, the paper finds that GPT-4o performs better in this context. However, it’s evident that while LLMs have potential, they currently fall short of replacing human programmers for complex, real-world development tasks.
Raw notes: Code LLMs love (new) benchmarks too. General perception is Claude Sonnet 3.5 is best in code generation. This paper’s findings differ: GPT-4o is the top dog. AI’s perf is still quite low (less than 30%).
NeuZip: Memory-Efficient Training and Inference with Dynamic Compression of Neural Networks
Dept. Computing Science & Alberta Machine Intelligence Institute (Amii), University of Alberta; Borealis AI
This paper introduces NeuZip, an innovative weight compression technique that effectively halves the memory footprint of neural networks without sacrificing performance quality. I’m impressed by how this approach smartly leverages floating-point entropy to achieve significant memory savings, notably reducing the training memory of large models like Llama-3 8B from 31GB to under 16GB. It challenges the notion that further efficiency gains in neural network architectures are infeasible, suggesting a promising direction for future exploration.
Raw notes: Tim Dettmers recently claimed that “From my own experience (a lot of failed research), you cannot cheat efficiency. If quantization fails, then also sparsification fails, and other efficiency mechanisms too. If this is true, we are close to optimal now.” Interesting thread to follow.

This paper delves into how chain-of-thought (CoT) prompting can actually degrade performance in large language models for tasks that are negatively impacted by explicit reasoning, similar to certain cognitive tasks in humans. Through empirical studies, it finds that CoT can significantly reduce accuracy, highlighting the importance of prompt selection based on the task’s nature. I found it particularly intriguing how understanding human cognitive challenges could enhance AI performance by informing more effective prompting strategies.

Raw notes: Can AI do feature engineering? There’s increasing interest in building AI/data scientists. Interesting excerpt: “Globally, the leaderboard is dominated by the O1-PREVIEW model, achieving an impressive performance of 11%+. The second tier consists of GEMINI models, the latest GPT-4O, and O1-MINI, followed by the best open source models (DEEPSEEK, MISTRAL LARGE), and CLAUDE SONNET. It takes at least a MIXTRAL 8X7B class model to offer a noticeable improvement over abstaining from processing the DataFrame.”
