The abstract presents research on how well Large Language Models (LLMs) align with brain cognitive processing signals when it comes to language processing. To answer this question, the authors employed Representational Similarity Analysis (RSA) to measure the alignment between 23 mainstream LLMs and fMRI signals of the brain. The study found that pre-training data size, model scaling, and alignment training positively correlate with LLM-brain similarity, while nonsensical prompts may attenuate this alignment. Furthermore, the authors discovered a high correlation between the performance of various LLM evaluations (MMLU, Chatbot Arena) and LLM-brain similarity.

This research explores how well Large Language Models (LLMs) match brain cognitive processing signals when it comes to language processing. Scientists used a special technique called Representational Similarity Analysis (RSA) to compare 23 popular LLMs with brain activity measured by fMRI. The results showed that the size of the data used to train the models, how big the models are, and training them specifically for this task all help improve the match between the models and brain signals. On the other hand, using nonsensical prompts can make it harder for the models to align with brain activity.
