MuLoCo: Muon is a Practical Inner Optimizer for DiLoCo

ICML 2026poster

DiLoCo is a powerful framework for training large language models (LLMs) under networking constraints, allowing for increased parallelism and accelerator utilization in data center settings. A critical but often overlooked factor in DiLoCo’s behavior is the choice of inner optimizer, which shapes th…

Improving Text Embeddings with Large Language Models

ACL 2024long

In this paper, we introduce a novel and simple method for obtaining high-quality text embeddings using only synthetic data and less than 1k training steps. Unlike existing methods that often depend on multi-stage intermediate pre-training with billions of weakly-supervised text pairs, followed by fi…

LABANet: Lead-Assisting Backbone Attention Network for Oral Multi-Pathology Segmentation

ICASSP 2023accepted

This paper presents a Lead-Assisting Backbone Attention Network (LABANet), which is able to perform multi-pathology instance segmentation of dental panoramic X-rays. A Lead-Assisting Attention Backbone (LAAB), containing two Swin-Transformers, is first developed for feature extraction. The following…

LexMAE: Lexicon-Bottlenecked Pretraining for Large-Scale Retrieval

ICLR 2023poster

In large-scale retrieval, the lexicon-weighting paradigm, learning weighted sparse representations in vocabulary space, has shown promising results with high quality and low latency. Despite it deeply exploiting the lexicon-representing capability of pre-trained language models, a crucial gap remain…

SimLM: Pre-training with Representation Bottleneck for Dense Passage Retrieval

ACL 2023long

In this paper, we propose SimLM (Similarity matching with Language Model pre-training), a simple yet effective pre-training method for dense passage retrieval. It employs a simple bottleneck architecture that learns to compress the passage information into a dense vector through self-supervised pre-…

Effective and Efficient Query-aware Snippet Extraction for Web Search

EMNLP 2022main

Query-aware webpage snippet extraction is widely used in search engines to help users better understand the content of the returned webpages before clicking. The extracted snippet is expected to summarize the webpage in the context of the input query. Existing snippet extraction methods mainly rely…

Learning Observation-Based Certifiable Safe Policy for Decentralized Multi-Robot Navigation

ICRA 2022poster

Safety is of great importance in multi-robot navigation problems. In this paper, we propose a control barrier function (CBF) based optimizer that ensures robot safety with both high probability and flexibility, using only sensor measurement. The optimizer takes action commands from the policy networ…
