Generalization of RLVR Using Causal Reasoning as a Testbed

ICLR 2026poster

Reinforcement learning with verifiable rewards (RLVR) has emerged as a promising paradigm for post-training large language models (LLMs) on complex reasoning tasks. Yet, the conditions under which RLVR yields robust generalization remain poorly understood. This paper provides an empirical study of R…

Geneverse: A Collection of Open-source Multimodal Large Language Models for Genomic and Proteomic Research

EMNLP 2024finding

The applications of large language models (LLMs) are promising for biomedical and healthcare research. Despite the availability of open-source LLMs trained using a wide range of biomedical data, current research on the applications of LLMs to genomics and proteomics is still limited. To fill this ga…

Semi-supervised Knowledge Transfer Across Multi-omic Single-cell Data

NeurIPS 2024poster

Knowledge transfer between multi-omic single-cell data aims to effectively transfer cell types from scRNA-seq data to unannotated scATAC-seq data. Several approaches aim to reduce the heterogeneity of multi-omic data while maintaining the discriminability of cell types with extensive annotated data.…

Superfiltering: Weak-to-Strong Data Filtering for Fast Instruction-Tuning

ACL 2024long

Instruction tuning is critical to improve LLMs but usually suffers from low-quality and redundant data. Data filtering for instruction tuning has proved important in improving both the efficiency and performance of the tuning process. But it also leads to extra cost and computation due to the involv…

MuSe-GNN: Learning Unified Gene Representation From Multimodal Biological Graph Data

NeurIPS 2023poster

Discovering genes with similar functions across diverse biomedical contexts poses a significant challenge in gene representation learning due to data heterogeneity. In this study, we resolve this problem by introducing a novel model called Multimodal Similarity Learning Graph Neural Network, which c…

Not All Classes are Equal: Adaptively Focus-Aware Confidence for Semi-Supervised Object Detection

ICASSP 2023accepted

Semi-supervised object detection (SSOD) is a significant application of Semi-supervised learning to further improve object detectors but suffers more seriously from confirmation bias and error accumulation caused by the classes imbalance. Existing SSOD approaches have attempted to address this issue…

Robustness of Learning from Task Instructions

ACL 2023findings

Traditional supervised learning mostly works on individual tasks and requires training on a large set of task-specific examples. This paradigm seriously hinders the development of task generalization since preparing a task-specific example set is costly. To build a system that can quickly and easily…

Tiny-Attention Adapter: Contexts Are More Important Than the Number of Parameters

EMNLP 2022main

Adapter-tuning is a paradigm that transfers a pretrained language model to downstream tasks by adding and tuning a small number of new parameters. Previously proposed adapter architectures are all feed-forward neural networks. In this paper, we investigate the effectiveness of using tiny-attention—i…

Inference of Dynamic Graph Changes for Functional Connectome

AISTATS 2020poster

Dynamic functional connectivity is an effective measure for the brain’s responses to continuous stimuli. We propose an inferential method to detect the dynamic changes of brain networks based on time-varying graphical models. Whereas most existing methods focus on testing the existence of change poi…
