Large Language Models for Sequential Decision-Making: Improving In-Context Learning via Supervised Fine-Tuning

📰 ArXiv cs.AI

Improve sequential decision-making with large language models using supervised fine-tuning for better in-context learning

advanced Published 12 May 2026
Action Steps
  1. Fine-tune a pre-trained large language model using supervised learning on a sequential decision-making task
  2. Apply the fine-tuned model to a Markov Decision Process (MDP) or Partially Observable MDP (POMDP) to evaluate its performance
  3. Use the model to make decisions in an Ambiguous POMDP (APOMDP) setting, where uncertainty is present
  4. Compare the performance of the fine-tuned model with other approaches, such as reinforcement learning
  5. Test the model's ability to generalize to new, unseen tasks or environments
Who Needs to Know This

Researchers and engineers working on sequential decision-making tasks, such as those in robotics or game playing, can benefit from this approach to improve their models' performance

Title: Large Language Models for Sequential Decision-Making: Improving In-Context Learning via Supervised Fine-Tuning

Abstract:
arXiv:2605.09009v1 Announce Type: cross Abstract: Large language models (LLMs) have shown remarkable in-context learning (ICL) capabilities, yet their potential for sequential decision-making remains underexplored. In this paper, we study the ICL capabilities of LLMs in sequential decision-making settings, including Markov Decision Processes (MDPs), Partially Observable MDPs (POMDPs), and Ambiguous POMDPs (APOMDPs). We fine-tune pretrained LLMs to perform few-shot decision-making directly from o
