PlugMem: A Task-Agnostic Plugin Memory Module for LLM Agents

ICML 2026poster

Long-term memory is essential for large language model (LLM) agents operating in complex environments, yet existing memory designs are either task-specific and non-transferable, or task-agnostic but less effective due to low task-relevance and context explosion from raw memory retrieval. We propose …

Guiding Through Complexity: What Makes Good Supervision for Hard Reasoning Tasks?

NAACL 2025long

How can “weak teacher models” (Bowman et al., 2022) such as average human annotators or existing AI systems, effectively supervise LLMs to improve performance on hard reasoning tasks, especially those that challenge and requires expertise or daily practice from the teacher models? In this paper, we…

MEGA-Bench: Scaling Multimodal Evaluation to over 500 Real-World Tasks

ICLR 2025poster

We present MEGA-Bench, an evaluation suite that scales multimodal evaluation to over 500 real-world tasks, to address the highly heterogeneous daily use cases of end users. Our objective is to optimize for a set of high-quality data samples that cover a highly diverse and rich set of multimodal task…

CF-Deformable DETR: An End-to-End Alignment-Free Model for Weakly Aligned Visible-Infrared Object Detection

IJCAI 2024poster

Weakly aligned visible-infrared object detection poses significant challenges due to the imprecise alignment between visible and infrared images. Most existing methods explore the alignment strategies between visible and infrared images, yielding unbearable computation costs. This paper first propos…

LocMoE: A Low-overhead MoE for Large Language Model Training

IJCAI 2024poster

The Mixtures-of-Experts (MoE) model is a widespread distributed and integrated learning method for large language models (LLM), which is favored due to its ability to sparsify and expand models efficiently. However, the performance of MoE is limited by load imbalance and high latency of All-to-All c…

MMLU-Pro: A More Robust and Challenging Multi-Task Language Understanding Benchmark

NeurIPS 2024spotlight

In the age of large-scale language models, benchmarks like the Massive Multitask Language Understanding (MMLU) have been pivotal in pushing the boundaries of what AI can achieve in language comprehension and reasoning across diverse domains. However, as models continue to improve, their performance…

VideoScore: Building Automatic Metrics to Simulate Fine-grained Human Feedback for Video Generation

EMNLP 2024main

The recent years have witnessed great advances in video generation. However, the development of automatic video metrics is lagging significantly behind. None of the existing metric is able to provide reliable scores over generated videos. The main barrier is the lack of large-scale human-annotated d…

Efficient Constrained Encoders Correcting a Single Nucleotide Edit in DNA Storage

ICASSP 2020accepted

A nucleotide substitution is said to occur when a base in {A, T} is substituted for a base in {C, G}, or vice versa. Recent experiment (Heckel et al. 2019) showed that a nucleotide substitution occurs with a significantly higher probability than other substitution errors. A nucleotide edit refers to…
