Dynamic Binary Neural Network by Learning Channel-Wise Thresholds

ICASSP 2022accepted

Binary neural networks (BNNs) constrain weights and activations to +1 or -1 with limited storage and computational cost, which is hardware-friendly for portable devices. Recently, BNNs have achieved remarkable progress and been adopted into various fields. However, the performance of BNNs is sensiti…

Pixel Difference Networks for Efficient Edge Detection

ICCV 2021poster

Recently, deep Convolutional Neural Networks (CNNs) can achieve human-level performance in edge detection with the rich and abstract edge representation capacities. However, the high performance of CNN based edge detection is achieved with a large pretrained CNN backbone, which is memory and energy…

Dynamic Group Convolution for Accelerating Convolutional Neural Networks

ECCV 2020poster

Replacing normal convolutions with group convolutions can significantly increase the computational efficiency of modern deep convolutional networks, which has been widely adopted in compact network architecture designs. However, existing group convolutions undermine the original network structures b…
