Designing Unimodular Waveforms for MIMO Radar Based on Manifold Optimization Method

no code implementations10 Oct 2024 Xuyang Zhao, Jiangtao Wang, Shihao Yan, Yongchao Wang

By embedding it into the search space, we transform the original non-convex optimization problem into an unconstrained problem on a Riemannian manifold.

A Statistical Theory of Regularization-Based Continual Learning

no code implementations10 Jun 2024 Xuyang Zhao, Huiyuan Wang, Weiran Huang, Wei Lin

Moreover, the estimation error of the optimal algorithm is derived explicitly, which is of the same order as that of the oracle estimator.

ArCL: Enhancing Contrastive Learning with Augmentation-Robust Representations

no code implementations2 Mar 2023 Xuyang Zhao, Tianqi Du, Yisen Wang, Jun Yao, Weiran Huang

Moreover, we show that contrastive learning fails to learn domain-invariant features, which limits its transferability.

Towards the Generalization of Contrastive Self-Supervised Learning

1 code implementation1 Nov 2021 Weiran Huang, Mingyang Yi, Xuyang Zhao, Zihao Jiang

It reveals that the generalization ability of contrastive self-supervised learning is related to three key factors: alignment of positive samples, divergence of class centers, and concentration of augmented data.
