TD learning fails to improve LLM few-shot retrieval on GSM8K

A researcher explored TD learning for improving retrieval of few-shot examples in LLM reasoning, aiming to assign learned values to traces based on their utility. The experiment involved storing reasoning traces, retrieving similar ones as examples, and updating their value based on subsequent solution quality. However, a simpler baseline that only considered the correctness of the trace's own solution performed equally well, suggesting the TD learning mechanism did not provide additional benefit on the GSM8K benchmark. AI

IMPACT Suggests that simpler baselines may suffice for certain LLM tasks, highlighting the need for more complex tasks to demonstrate advanced learning mechanisms.
