OmniGround: A Comprehensive Spatio-Temporal Grounding Benchmark for Real-World Complex Scenarios

CVPR 2026

Spatio-Temporal Video Grounding (STVG) aims to localize target objects in videos based on natural language descriptions. While Multimodal Large Language Models have shown promise, a significant gap remains between current models and real-world demands involving diverse objects and complex queries. W

LLMC: Benchmarking Large Language Model Quantization with a Versatile Compression Toolkit

EMNLP 2024industry

Recent advancements in large language models (LLMs) are propelling us toward artificial general intelligence with their remarkable emergent abilities and reasoning capabilities. However, the substantial computational and memory requirements limit the widespread adoption. Quantization, a key compress…

Outlier Suppression+: Accurate quantization of large language models by equivalent and effective shifting and scaling

EMNLP 2023long main

Post-training quantization (PTQ) of transformer language models faces significant challenges due to the existence of detrimental outliers in activations. We observe that these outliers are concentrated in specific channels and are asymmetric across channels. To address this issue, we propose the Out…

Outlier Suppression: Pushing the Limit of Low-bit Transformer Language Models

NeurIPS 2022accept

Transformer architecture has become the fundamental element of the widespread natural language processing~(NLP) models. With the trends of large NLP models, the increasing memory and computation costs hinder their efficient deployment on resource-limited devices. Therefore, transformer quantization…

Perceiving and Modeling Density for Image Dehazing

ECCV 2022poster

"In the real world, the degradation of images taken under haze can be quite complex, where the spatial distribution of haze varies from image to image. Recent methods adopt deep neural networks to recover clean scenes from hazy images directly. However, due to the generic design of network architect…
