Horospherical Decision Boundaries for Large Margin Classification in Hyperbolic Space

NeurIPS 2023poster

Hyperbolic spaces have been quite popular in the recent past for representing hierarchically organized data. Further, several classification algorithms for data in these spaces have been proposed in the literature. These algorithms mainly use either hyperplanes or geodesics for decision boundaries i…

Nested Hyperbolic Spaces for Dimensionality Reduction and Hyperbolic NN Design

CVPR 2022poster

Hyperbolic neural networks have been popular in the recent past due to their ability to represent hierarchical data sets effectively and efficiently. The challenge in developing these networks lies in the nonlinearity of the embedding space namely, the Hyperbolic space. Hyperbolic space is a homogen…

A Statistical Recurrent Model on the Manifold of Symmetric Positive Definite Matrices

NeurIPS 2018poster

In a number of disciplines, the data (e.g., graphs, manifolds) to be analyzed are non-Euclidean in nature. Geometric deep learning corresponds to techniques that generalize deep neural network models to such non-Euclidean spaces. Several recent papers have shown how convolutional neural networks (C…
