A spectral-spatial fusion anomaly detection method for hyperspectral imagery

no code implementations24 Feb 2022 Zengfu Hou, Siyuan Cheng, Ting Hu

In hyperspectral, high-quality spectral signals convey subtle spectral differences to distinguish similar materials, thereby providing unique advantage for anomaly detection.

DiriNet: A network to estimate the spatial and spectral degradation functions

no code implementations27 Jan 2022 Ting Hu

To learn the spatial response function and the point spread function from the image pairs to be fused, we propose a Dirichlet network, where both functions are properly constrained.

A Permutation-Invariant Representation of Neural Networks with Neuron Embeddings

no code implementations29 Sep 2021 Ryan Zhou, Christian Muise, Ting Hu

A key property of this representation is that there are multiple representations of a network which can be obtained by permuting the order of the neurons.

Stochastic Gradient Descent for Nonconvex Learning without Bounded Gradient Assumptions

no code implementations3 Feb 2019 Yunwen Lei, Ting Hu, Guiying Li, Ke Tang

While the behavior of SGD is well understood in the convex learning setting, the existing theoretical results for SGD applied to nonconvex objective functions are far from mature.

Consistency Analysis of an Empirical Minimum Error Entropy Algorithm

no code implementations17 Dec 2014 Jun Fan, Ting Hu, Qiang Wu, Ding-Xuan Zhou

The error entropy consistency, which requires the error entropy of the learned function to approximate the minimum error entropy, is shown to be always true if the bandwidth parameter tends to 0 at an appropriate rate.
