Easier to Judge than to Find: Predicting In-Context Learning Success for Demonstration Selection

ICML 2026poster

In-context learning (ICL) is highly sensitive to which demonstrations appear in the prompt, but selecting them is expensive because candidate contexts must be validated with repeated LLM calls. We argue that demonstration selection is \emph{easier to judge than to find}: predicting whether a specifi…

AS-ES Learning: Towards efficient CoT learning in small models

ACL 2024findings

Chain-of-Thought (CoT) serves as a critical emerging ability in LLMs, especially when it comes to logical reasoning. Attempts have been made to induce such ability in small models as well by distilling from the data with CoT generated by Large Language Models (LLMs). However, existing methods often…

Manifold-Based Verbalizer Space Re-embedding for Tuning-Free Prompt-Based Classification

AAAI 2024technical

Prompt-based classification adapts tasks to a cloze question format utilizing the [MASK] token and the filled tokens are then mapped to labels through pre-defined verbalizers. Recent studies have explored the use of verbalizer embeddings to reduce labor in this process. However, all existing studies…

Prompt Combines Paraphrase: Teaching Pre-trained Models to Understand Rare Biomedical Words

COLING 2022main

Prompt-based fine-tuning for pre-trained models has proven effective for many natural language processing tasks under few-shot settings in general domain. However, tuning with prompt in biomedical domain has not been investigated thoroughly. Biomedical words are often rare in general domain, but qui…
