CAMERA: Multi-Matrix Joint Compression for MoE Models via Micro-Expert Redundancy Analysis

AAAI 2026technical

Large Language Models (LLMs) with Mixture-of-Experts (MoE) architectures are distinguished by their strong performance scaling with increasing parameters across a wide range of tasks, yet they also suffer from substantial computational and storage overheads. Notably, the performance gains of MoE mod

Judge Q: Trainable Queries for Optimized Information Retention in KV Cache Eviction

AAAI 2026technical

Large language models (LLMs) utilize key-value (KV) cache to store historical information during sequence processing. The size of KV cache grows linearly as the length of the sequence extends, which seriously affects memory usage and decoding efficiency. Current methods for KV cache eviction typical

C2AD: Dual Consistency Learning for Zero-Shot Anomaly Detection

ICASSP 2025accepted

Zero-shot anomaly detection (ZSAD) is dedicated to detecting anomalies without having any seen normal or abnormal samples for the target set. Existing approaches utilize the pre-trained CLIP to assess normality/abnormality by exploiting the similarity between images and text with the frozen visual e…

CVLUE: A New Benchmark Dataset for Chinese Vision-Language Understanding Evaluation

AAAI 2025technical

Despite the rapid development of Chinese vision-language models (VLMs), most existing Chinese vision-language (VL) datasets are constructed on Western-centric images from existing English VL datasets. The cultural bias in the images makes these datasets unsuitable for evaluating VLMs in Chinese cult…

Lookahead Q-Cache: Achieving More Consistent KV Cache Eviction via Pseudo Query

EMNLP 2025

Large language models (LLMs) rely on key-value cache (KV cache) to accelerate decoding by reducing redundant computations. However, the KV cache memory usage grows substantially with longer text sequences, posing challenges for efficient deployment. Existing KV cache eviction methods prune tokens us

Domain-aware and Co-adaptive Feature Transformation for Domain Adaption Few-shot Relation Extraction

COLING 2024main

Few-shot relation extraction (FSRE) can alleviate the data scarcity problem in relation extraction. However, FSRE models often suffer a significant decline in performance when adapting to new domains. To overcome this issue, many researchers have focused on domain adaption FSRE (DAFSRE). Nevertheles…

Improving Grammatical Error Correction via Contextual Data Augmentation

ACL 2024findings

Nowadays, data augmentation through synthetic data has been widely used in the field of Grammatical Error Correction (GEC) to alleviate the problem of data scarcity. However, these synthetic data are mainly used in the pre-training phase rather than the data-limited fine tuning phase due to inconsis…

LM-Combiner: A Contextual Rewriting Model for Chinese Grammatical Error Correction

COLING 2024main

Over-correction is a critical problem in Chinese grammatical error correction (CGEC) task. Recent work using model ensemble methods based on voting can effectively mitigate over-correction and improve the precision of the GEC system. However, these methods still require the output of several GEC sys…

Make Some Noise: Unlocking Language Model Parallel Inference Capability through Noisy Training

EMNLP 2024main

Existing speculative decoding methods typically require additional model structure and training processes to assist the model for draft token generation. This makes the migration of acceleration methods to the new model more costly and more demanding on device memory. To address this problem, we pro…

SVGA-Net: Sparse Voxel-Graph Attention Network for 3D Object Detection from Point Clouds

AAAI 2022technical

Accurate 3D object detection from point clouds has become a crucial component in autonomous driving. However, the volumetric representations and the projection methods in previous works fail to establish the relationships between the local point sets. In this paper, we propose Sparse Voxel-Graph Att…

PD-GAN: Perceptual-Details GAN for Extremely Noisy Low Light Image Enhancement

ICASSP 2021accepted

Extremely noisy low light enhancement suffers from high-level noise, loss of texture detail, and color degradation. When recovering color or illumination for images taken in a dark environment, the challenge for networks is how to balance the enhancement for noise and texture details for a good visu…
