MOSEL: Inference Serving Using Dynamic Modality Selection

no code implementations27 Oct 2023 Bodun Hu, Le Xu, Jeongyoon Moon, Neeraja J. Yadwadkar, Aditya Akella

Rapid advancements over the years have helped machine learning models reach previously hard-to-achieve goals, sometimes even exceeding human capabilities.

Adversarial Self-Attack Defense and Spatial-Temporal Relation Mining for Visible-Infrared Video Person Re-Identification

no code implementations8 Jul 2023 Huafeng Li, Le Xu, Yafei Zhang, Dapeng Tao, Zhengtao Yu

In this work, the changes of views, posture, background and modal discrepancy are considered as the main factors that cause the perturbations of person identity features.

Adversarial Attack Video-Based Person Re-Identification

Overcoming Beam Squint in Dual-Wideband mmWave MIMO Channel Estimation: A Bayesian Multi-Band Sparsity Approach

no code implementations19 Jun 2023 Le Xu, Lei Cheng, Ngai Wong, Yik-Chung Wu, H. Vincent Poor

A probabilistic model is built to induce the common sparsity in the spatial domain, and the first-order Taylor expansion is adopted to get rid of the grid mismatch in the dictionaries.

To Fold or Not to Fold: Graph Regularized Tensor Train for Visual Data Completion

1 code implementation19 Jun 2023 Le Xu, Lei Cheng, Ngai Wong, Yik-Chung Wu

Tensor train (TT) representation has achieved tremendous success in visual data completion tasks, especially when it is combined with tensor folding.

Low-rank Adaptation Method for Wav2vec2-based Fake Audio Detection

no code implementations9 Jun 2023 Chenglong Wang, Jiangyan Yi, Xiaohui Zhang, JianHua Tao, Le Xu, Ruibo Fu

Self-supervised speech models are a rapidly developing research topic in fake audio detection.

Adaptive Fake Audio Detection with Low-Rank Model Squeezing

no code implementations8 Jun 2023 Xiaohui Zhang, Jiangyan Yi, JianHua Tao, Chenlong Wang, Le Xu, Ruibo Fu

During the inference stage, these adaptation matrices are combined with the existing model to generate the final prediction output.

Detection of brain activations induced by naturalistic stimuli in a pseudo model-driven way

no code implementations3 Dec 2022 Jiangcong Liu, Hao Ma, Yun Guan, Fan Wu, Le Xu, Yang Zhang, Lixia Tian

We evaluated the effectiveness of AINS with both statistical and predictive analyses on individual differences in sex and intelligence quotient (IQ), based on the four movie fMRI runs included in the Human Connectome Project dataset.

Tensor Train Factorization and Completion under Noisy Data with Prior Analysis and Rank Estimation
