Helix: Evolutionary Reinforcement Learning for Open-Ended Scientific Problem Solving

ICLR 2026poster

Large language models (LLMs) with reasoning abilities have demonstrated growing promise for tackling complex scientific problems. Yet such tasks are inherently domain-specific, unbounded and open-ended, demanding exploration across vast and flexible solution spaces. Existing approaches, whether pure…

X-MoGen: Unified Motion Generation Across Humans and Animals

AAAI 2026technical

Text-driven motion generation has attracted increasing attention due to its broad applications in virtual reality, animation, and robotics. While existing methods typically model human and animal motion separately, a joint cross-species approach offers key advantages, such as a unified representatio

Democratizing Clinical Risk Prediction with Cross-Cohort Cross-Modal Knowledge Transfer

NeurIPS 2025poster

Clinical risk prediction plays a crucial role in early disease detection and personalized intervention. While recent models increasingly incorporate multimodal data, their development typically assumes access to large-scale, multimodal datasets and substantial computational resources. In practice, h…

Training LLMs to be Better Text Embedders through Bidirectional Reconstruction

EMNLP 2025

Large language models (LLMs) have increasingly been explored as powerful text embedders. Existing LLM-based text embedding approaches often leverage the embedding of the final token, typically a reserved special token such as ‘[EOS]‘. However, these tokens have not been intentionally trained to capt

CB-Whisper: Contextual Biasing Whisper Using Open-Vocabulary Keyword-Spotting

COLING 2024main

End-to-end automatic speech recognition (ASR) systems often struggle to recognize rare name entities, such as personal names, organizations and terminologies that are not frequently encountered in the training data. This paper presents Contextual Biasing Whisper (CB-Whisper), a novel ASR system base…

DPOT: Auto-Regressive Denoising Operator Transformer for Large-Scale PDE Pre-Training

ICML 2024poster

Pre-training has been investigated to improve the efficiency and performance of training neural operators in data-scarce settings. However, it is largely in its infancy due to the inherent complexity and diversity, such as long trajectories, multiple scales and varying dimensions of partial differen…

PINNacle: A Comprehensive Benchmark of Physics-Informed Neural Networks for Solving PDEs

NeurIPS 2024poster

While significant progress has been made on Physics-Informed Neural Networks (PINNs), a comprehensive comparison of these methods across a wide range of Partial Differential Equations (PDEs) is still lacking. This study introduces PINNacle, a benchmarking tool designed to fill this gap. PINNacle pro…

UCorrect: An Unsupervised Framework for Automatic Speech Recognition Error Correction

ICASSP 2023accepted

Error correction techniques have been used to refine the output sentences from automatic speech recognition (ASR) models and achieve a lower word error rate (WER). Previous works usually adopt end-to-end models and has strong dependency on Pseudo Paired Data and Original Paired Data. But when only p…

Capture Human Disagreement Distributions by Calibrated Networks for Natural Language Inference

ACL 2022findings

Natural Language Inference (NLI) datasets contain examples with highly ambiguous labels due to its subjectivity. Several recent efforts have been made to acknowledge and embrace the existence of ambiguity, and explore how to capture the human disagreement distribution. In contrast with directly lear…

Probing Simile Knowledge from Pre-trained Language Models

ACL 2022long

Simile interpretation (SI) and simile generation (SG) are challenging tasks for NLP because models require adequate world knowledge to produce predictions. Previous works have employed many hand-crafted resources to bring knowledge-related into models, which is time-consuming and labor-intensive. In…

Collision-Free Path Planning of Dual-Manipulator System Based on Energy Conversion

IROS 2018poster

This paper is a preliminary exploration of how to solve the dual-manipulator path-planning problem from an energy perspective. A virtual spring is set up between the two manipulator bodies and becomes compressed as they move into the area of danger, thus producing elastic potential energy. The initi…

A real-time example-based single-image super-resolution algorithm via cross-scale high-frequency components self-learning

ICASSP 2016accepted

In this paper, we propose a fast and dictionary-free example-based super-resolution (EBSR) algorithm to solve the contradiction in EBSR methods of their high performance in achieving high visual quality and their low efficiency and high costs. With a novel cross-scale high-frequency components (HFC)…
