Learning to Solve Complex Problems via Dataset Decomposition

NeurIPS 2025poster

Curriculum learning is a class of training strategies that organizes the data being exposed to a model by difficulty, gradually from simpler to more complex examples. This research explores a reverse curriculum generation approach that recursively decomposes complex datasets into simpler, more lear…

fLSA: Learning Semantic Structures in Document Collections Using Foundation Models

EMNLP 2025

Humans can learn to solve new tasks by inducing high-level strategies from example solutions to similar problems and then adapting these strategies to solve unseen problems. Can we use large language models to induce such high-level structure from example documents or solutions? We introduce fLSA, a

Reprompting: Automated Chain-of-Thought Prompt Inference Through Gibbs Sampling

ICML 2024poster

We introduce Reprompting, an iterative sampling algorithm that automatically learns the Chain-of-Thought (CoT) recipes for a given task without human intervention. Through Gibbs sampling, Reprompting infers the CoT recipes that work consistently well for a set of training samples by iteratively samp…

Constrained Regeneration for Cross-Lingual Query-Focused Extractive Summarization

COLING 2022main

Query-focused summaries of foreign-language, retrieved documents can help a user understand whether a document is actually relevant to the query term. A standard approach to this problem is to first translate the source documents and then perform extractive summarization to find relevant snippets. H…

Improving Multilingual Neural Machine Translation with Auxiliary Source Languages

EMNLP 2021finding

Multilingual neural machine translation models typically handle one source language at a time. However, prior work has shown that translating from multiple source languages improves translation quality. Different from existing approaches on multi-source translation that are limited to the test scena…
