BIFRNet: A Brain-Inspired Feature Restoration DNN for Partially Occluded Image Recognition

1 code implementation2 Mar 2023 Jiahong Zhang, Lihong Cao, Qiuxia Lai, Binyao Li, Yunxiao Qin

Several studies in neuroscience reveal that feature restoration which fills in the occluded information and is called amodal completion is essential for human brains to recognize partially occluded images.

DeepSAT: An EDA-Driven Learning Framework for SAT

no code implementations27 May 2022 Min Li, Zhengyuan Shi, Qiuxia Lai, Sadaf Khan, Shaowei Cai, Qiang Xu

Based on this observation, we approximate the SAT solving procedure with a conditional generative model, leveraging a novel directed acyclic graph neural network (DAGNN) with two polarity prototypes for conditional SAT modeling.

T-WaveNet: A Tree-Structured Wavelet Neural Network for Time Series Signal Analysis

no code implementations ICLR 2022 Minhao Liu, Ailing Zeng, Qiuxia Lai, Ruiyuan Gao, Min Li, Jing Qin, Qiang Xu

In this work, we propose a novel tree-structured wavelet neural network for time series signal analysis, namely T-WaveNet, by taking advantage of an inherent property of various types of signals, known as the dominant frequency range.

Information Bottleneck Approach to Spatial Attention Learning

1 code implementation7 Aug 2021 Qiuxia Lai, Yu Li, Ailing Zeng, Minhao Liu, Hanqiu Sun, Qiang Xu

Extensive experiments show that the proposed IB-inspired spatial attention mechanism can yield attention maps that neatly highlight the regions of interest while suppressing backgrounds, and bootstrap standard DNN structures for visual recognition tasks (e. g., image classification, fine-grained recognition, cross-domain classification).

SCINet: Time Series Modeling and Forecasting with Sample Convolution and Interaction

3 code implementations17 Jun 2021 Minhao Liu, Ailing Zeng, Muxi Chen, Zhijian Xu, Qiuxia Lai, Lingna Ma, Qiang Xu

One unique property of time series is that the temporal relations are largely preserved after downsampling into two sub-sequences.

T-WaveNet: Tree-Structured Wavelet Neural Network for Sensor-Based Time Series Analysis

no code implementations10 Dec 2020 Minhao Liu, Ailing Zeng, Qiuxia Lai, Qiang Xu

Motivated by the fact that usually a small subset of the frequency components carries the primary information for sensor data, we propose a novel tree-structured wavelet neural network for sensor data analysis, namely \emph{T-WaveNet}.

DeepFuse: An IMU-Aware Network for Real-Time 3D Human Pose Estimation from Multi-View Image

no code implementations9 Dec 2019 Fuyang Huang, Ailing Zeng, Minhao Liu, Qiuxia Lai, Qiang Xu

In this paper, we propose a two-stage fully 3D network, namely \textbf{DeepFuse}, to estimate human pose in 3D space by fusing body-worn Inertial Measurement Unit (IMU) data and multi-view images deeply.

Understanding More about Human and Machine Attention in Deep Neural Networks

no code implementations20 Jun 2019 Qiuxia Lai, Salman Khan, Yongwei Nie, Jianbing Shen, Hanqiu Sun, Ling Shao

With three example computer vision tasks, diverse representative backbones, and famous architectures, corresponding real human gaze data, and systematically conducted large-scale quantitative studies, we quantify the consistency between artificial attention and human visual attention and offer novel insights into existing artificial attention mechanisms by giving preliminary answers to several key questions related to human and artificial attention mechanisms.
