Convergence Analysis for Learning Orthonormal Deep Linear Neural Networks

no code implementations24 Nov 2023 Zhen Qin, Xuwei Tan, Zhihui Zhu

Enforcing orthonormal or isometric property for the weight matrices has been shown to enhance the training of deep neural networks by mitigating gradient exploding/vanishing and increasing the robustness of the learned networks.

Prototype Fission: Closing Set for Robust Open-set Semi-supervised Learning

no code implementations29 Aug 2023 Xuwei Tan, Yi-Jie Huang, Yaqian Li

Instead of "opening set", i. e., modeling OOD distribution, Prototype Fission "closes set" and makes it hard for OOD samples to fit in sub-class latent space.
