Hierarchical Retrieval with Evidence Curation for Open-Domain Financial Question Answering on Standardized Documents

ACL 2025finding

Retrieval-augmented generation (RAG) based large language models (LLMs) are widely used in finance for their excellent performance on knowledge-intensive tasks. However, standardized documents (e.g., SEC filing) share similar formats such as repetitive boilerplate texts,and similar table structures.…

Robust and Expressive Humanoid Motion Retargeting via Optimization-Based Rig Unification

IROS 2025

Humanoid robots are increasingly being developed for seamless interaction with humans in diverse domains, yet generating expressive and physically-feasible motions remains a core challenge. We propose a robust and automated pipeline for motion retargeting that enables the generation of natural, stab

Web Agents with World Models: Learning and Leveraging Environment Dynamics in Web Navigation

ICLR 2025poster

Large language models (LLMs) have recently gained much attention in building autonomous agents. However, performance of current LLM-based web agents in long-horizon tasks is far from optimal, often yielding errors such as repeatedly buying a non-refundable flight ticket. By contrast, humans can avoi…

BubbleML: A Multiphase Multiphysics Dataset and Benchmarks for Machine Learning

NeurIPS 2023spotlight

In the field of phase change phenomena, the lack of accessible and diverse datasets suitable for machine learning (ML) training poses a significant challenge. Existing experimental datasets are often restricted, with limited availability and sparse ground truth, impeding our understanding of this co…

X-SNS: Cross-Lingual Transfer Prediction through Sub-Network Similarity

EMNLP 2023long findings

Cross-lingual transfer (XLT) is an emergent ability of multilingual language models that preserves their performance on a task to a significant extent when evaluated in languages that were not included in the fine-tuning process. While English, due to its widespread usage, is typically regarded as t…

Simulation-guided Beam Search for Neural Combinatorial Optimization

NeurIPS 2022accept

Neural approaches for combinatorial optimization (CO) equip a learning mechanism to discover powerful heuristics for solving complex real-world problems. While neural approaches capable of high-quality solutions in a single shot are emerging, state-of-the-art approaches are often unable to take full…

VaB-AL: Incorporating Class Imbalance and Difficulty With Variational Bayes for Active Learning

CVPR 2021poster

Active Learning for discriminative models has largely been studied with the focus on individual samples, with less emphasis on how classes are distributed or which classes are hard to deal with. In this work, we show that this is harmful. We propose a method based on the Bayes' rule, that can natura…
