Center Prediction Loss for Re-identification

no code implementations30 Apr 2021 Lu Yang, Yunlong Wang, Lingqiao Liu, Peng Wang, Lu Chi, Zehuan Yuan, Changhu Wang, Yanning Zhang

In this paper, we propose a new loss based on center predictivity, that is, a sample must be positioned in a location of the feature space such that from it we can roughly predict the location of the center of same-class samples.

Fast Fourier Convolution

1 code implementation NeurIPS 2020 Lu Chi, Borui Jiang, Yadong Mu

FFC is a generic operator that can directly replace vanilla convolutions in a large body of existing networks, without any adjustments and with comparable complexity metrics (e. g., FLOPs).

Non-Local Neural Networks With Grouped Bilinear Attentional Transforms

3 code implementations CVPR 2020 Lu Chi, Zehuan Yuan, Yadong Mu, Changhu Wang

The core of our method is learnable and data-adaptive bilinear attentional transform (BA-Transform), whose merits are three-folds: first, BA-Transform is versatile to model a wide spectrum of local or global attentional operations, such as emphasizing specific local regions.

Fast Non-Local Neural Networks with Spectral Residual Learning

1 code implementation MM '19: Proceedings of the 27th ACM International Conference on Multimedia 2019 Lu Chi, Guiyu Tian, Yadong Mu, Lingxi Xie, Qi Tian

We show its equivalence to conducting residual learning in some spectral domain and carefully re-formulate a variety of neural layers into their spectral forms, such as ReLU or convolutions.

Two-Stream Video Classification with Cross-Modality Attention

no code implementations1 Aug 2019 Lu Chi, Guiyu Tian, Yadong Mu, Qi Tian

In the experiments, we comprehensively compare our method with two-stream and non-local models widely used in video classification.

Deep Steering: Learning End-to-End Driving Model from Spatial and Temporal Visual Cues

1 code implementation12 Aug 2017 Lu Chi, Yadong Mu

There are multiple fronts to these endeavors, including object detection on roads, 3-D reconstruction etc., but in this work we focus on a vision-based model that directly maps raw input images to steering angles using deep networks.
