RevColV2: Exploring Disentangled Representations in Masked Image Modeling

1 code implementation NeurIPS 2023 Qi Han, Yuxuan Cai, Xiangyu Zhang

Such design enables our architecture with the nice property: maintaining disentangled low-level and semantic information at the end of the network in MIM pre-training.

Reversible Column Networks

1 code implementation22 Dec 2022 Yuxuan Cai, Yizhuang Zhou, Qi Han, Jianjian Sun, Xiangwen Kong, Jun Li, Xiangyu Zhang

Such architectural scheme attributes RevCol very different behavior from conventional networks: during forward propagation, features in RevCol are learned to be gradually disentangled when passing through each column, whose total information is maintained rather than compressed or discarded as other network does.

Representative Batch Normalization With Feature Calibration

no code implementations CVPR 2021 Shang-Hua Gao, Qi Han, Duo Li, Ming-Ming Cheng, Pai Peng

We propose to add a simple yet effective feature calibration scheme into the centering and scaling operations of BatchNorm, enhancing the instance-specific representations with the negligible computational cost.

On the Connection between Local Attention and Dynamic Depth-wise Convolution

1 code implementation ICLR 2022 Qi Han, Zejia Fan, Qi Dai, Lei Sun, Ming-Ming Cheng, Jiaying Liu, Jingdong Wang

Sparse connectivity: there is no connection across channels, and each position is connected to the positions within a small local window.

Search What You Want: Barrier Panelty NAS for Mixed Precision Quantization

no code implementations ECCV 2020 Haibao Yu, Qi Han, Jianbo Li, Jianping Shi, Guangliang Cheng, Bin Fan

Learning to find an optimal mixed precision model that can preserve accuracy and satisfy the specific constraints on model size and computation is extremely challenge due to the difficult in training a mixed precision model and the huge space of all possible bit quantizations.

Dependency Aware Filter Pruning

no code implementations6 May 2020 Kai Zhao, Xin-Yu Zhang, Qi Han, Ming-Ming Cheng

Convolutional neural networks (CNNs) are typically over-parameterized, bringing considerable computational overhead and memory footprint in inference.

Deep Hough Transform for Semantic Line Detection

2 code implementations ECCV 2020 Kai Zhao, Qi Han, Chang-Bin Zhang, Jun Xu, Ming-Ming Cheng

In addition to the proposed method, we design an evaluation metric to assess the quality of line detection and construct a large scale dataset for the line detection task.
