A Tensor-based Convolutional Neural Network for Small Dataset Classification

no code implementations29 Mar 2023 Zhenhua Chen, David Crandall

Inspired by the ConvNets with structured hidden representations, we propose a Tensor-based Neural Network, TCNN.

Crafting Adversarial Examples for Neural Machine Translation

no code implementations ACL 2021 Xinze Zhang, Junzhe Zhang, Zhenhua Chen, Kun He

We first show the current NMT adversarial attacks may be improperly estimated by the commonly used mono-directional translation, and we propose to leverage the round-trip translation technique to build valid metrics for evaluating NMT adversarial attacks.

How to Accelerate Capsule Convolutions in Capsule Networks

no code implementations6 Apr 2021 Zhenhua Chen, Xiwen Li, Qian Lou, David Crandall

How to improve the efficiency of routing procedures in CapsNets has been studied a lot.

P-CapsNets: a General Form of Convolutional Neural Networks

no code implementations18 Dec 2019 Zhenhua Chen, Xiwen Li, Chuhua Wang, David Crandall

The experiment shows that P-CapsNets achieve better performance than CapsNets with varied routing procedures by using significantly fewer parameters on MNIST\&CIFAR10.

Generalized Capsule Networks with Trainable Routing Procedure

1 code implementation ICLR 2019 Zhenhua Chen, David Crandall

To overcome this disadvantages of current routing procedures in CapsNet, we embed the routing procedure into the optimization procedure with all other parameters in neural networks, namely, make coupling coefficients in the routing procedure become completely trainable.

Detecting Small, Densely Distributed Objects with Filter-Amplifier Networks and Loss Boosting

no code implementations21 Feb 2018 Zhenhua Chen, David Crandall, Robert Templeman

Detecting small, densely distributed objects is a significant challenge: small objects often contain less distinctive information compared to larger ones, and finer-grained precision of bounding box boundaries are required.
