Lie Group Auto-Encoder

no code implementations28 Jan 2019 Liyu Gong, Qiang Cheng

Moreover, we derive an intrinsic loss for UTDAT Lie group which can be calculated as l-2 loss in the tangent space.

Exploiting Edge Features in Graph Neural Networks

no code implementations7 Sep 2018 Liyu Gong, Qiang Cheng

The proposed framework can consolidate current graph neural network models; e. g. graph convolutional networks (GCN) and graph attention networks (GAT).

Lie Algebrized Gaussians for Image Representation

no code implementations3 Apr 2013 Liyu Gong, Meng Chen, Chunlong Hu

Then we vectorize the GMMs based on two facts: (1) components of image-specific GMMs are closely grouped together around their corresponding component of the UBM due to the characteristic of the UBM adaption procedure; (2) Gaussian \emph{pdf}s form a Lie group, which is a differentiable manifold rather than a vector space.
