Reasoning Compartmentalization: Bridging the Concretization Gap via Abstraction-based Routing

ICML 2026poster

While previous research has documented the sensitivity of Large Language Models (LLMs) to surface-level performance degradation, the underlying impact on internal representations and learning dynamics remains under-explored. In this work, we study this question using a controlled setup with paired r…

Fusion-OSR: Cross-Domain Contrastive Learning with Weibull Calibration for Time Series Open Set Recognition

ICASSP 2025accepted

In recent years, numerous Time Series Anomaly Detection methods have emerged, focusing primarily on detecting anomalies within time series, with limited work on open set recognition. In real-world scenarios, obtaining anomaly data is challenging. We can acquire a limited number of samples representi…

Improving Continual Pre-training Through Seamless Data Packing

ACL 2025finding

Continual pre-training has demonstrated significant potential in enhancing model performance, particularly in domain-specific scenarios. The most common approach for packing data before continual pre-training involves concatenating input texts and splitting them into fixed-length sequences. While st…

UMSSS: A Visual Scene Semantic Segmentation Dataset for Underground Mines

ICASSP 2025accepted

Specialized datasets designed for mining scenarios are the essential foundation for the development, operation, and research of intelligent mines. Currently, the available datasets focus primarily on open-pit mines, with a lack of specialized datasets for underground mines. This gap severely hinders…

FlashAvatar: High-fidelity Head Avatar with Efficient Gaussian Embedding

CVPR 2024poster

We propose FlashAvatar a novel and lightweight 3D animatable avatar representation that could reconstruct a digital avatar from a short monocular video sequence in minutes and render high-fidelity photo-realistic images at 300FPS on a consumer-grade GPU. To achieve this we maintain a uniform 3D Gaus…

Searching for Best Practices in Retrieval-Augmented Generation

EMNLP 2024main

Retrieval-augmented generation (RAG) techniques have proven to be effective in integrating up-to-date information, mitigating hallucinations, and enhancing response quality, particularly in specialized domains. While many RAG approaches have been proposed to enhance large language models through que…
