• Title: LLMs are Not Just Next Token Predictors
• Authors: Stephen M. Downes, Patrick Forber, Alex Grzankowski,
• Abstract summary: LLMs are statistical models of language learning through gradient descent with a next token prediction objective. While LLMs are engineered using next token prediction, and trained based on their success at this task, our view is that a reduction to just next token predictor sells LLMs short. In order to draw this out, we will make an analogy with a once prominent research program in biology explaining evolution and development from the gene's eye view.

• Abstract: LLMs are statistical models of language learning through stochastic gradient descent with a next token prediction objective. Prompting a popular view among AI modelers: LLMs are just next token predictors. While LLMs are engineered using next token prediction, and trained based on their success at this task, our view is that a reduction to just next token predictor sells LLMs short. Moreover, there are important explanations of LLM behavior and capabilities that are lost when we engage in this kind of reduction. In order to draw this out, we will make an analogy with a once prominent research program in biology explaining evolution and development from the gene's eye view.

  This study investigates the computational redundancy in the vision component of Multimodal Large Language Models (MLLMs) After pruning, the computation growth in the LLM is no longer quadratic with the increase of visual tokens, but linear. This finding opens up the possibility for MLLMs to incorporate much denser visual tokens.

  How can small-scale large language models (LLMs) efficiently utilize the supervision of LLMs to improve their generative quality? We develop an algorithm to effectively aggregate the small-scale LLM and LLM predictions on initial tokens. We demonstrate that our method provides a consistent improvement over conventional decoding strategies.

  Large language model (LLM) empowered agents are able to solve decision-making problems in the physical world. Under this model, the LLM Planner navigates a partially observable Markov decision process (POMDP) by iteratively generating language-based subgoals via prompting. We prove that the pretrained LLM Planner effectively performs Bayesian aggregated imitation learning (BAIL) through in-context learning.

  We propose a framework to teach Large Language Models (LLMs) to generate explainable stock predictions. A reflective agent learns how to explain past stock movements through self-reasoning, while the PPO trainer trains the model to generate the most likely explanations. Our framework can outperform both traditional deep-learning and LLM methods in prediction accuracy and Matthews correlation coefficient.
