An Homogeneous Unbalanced Regularized Optimal Transport Model with Applications to Optimal Transport with Boundary

AISTATS 2023poster

This work studies how the introduction of the entropic regularization term in unbalanced Optimal Transport (OT) models may alter their homogeneity with respect to the input measures. We observe that in common settings (including balanced OT and unbalanced OT with Kullback-Leibler divergence to the m…

PersLay: A Neural Network Layer for Persistence Diagrams and New Graph Topological Signatures

AISTATS 2020poster

Persistence diagrams, the most common descriptors of Topological Data Analysis, encode topological properties of data and have already proved pivotal in many different applications of data science. However, since the metric space of persistence diagrams is not Hilbert, they end up being difficult in…

Large Scale computation of Means and Clusters for Persistence Diagrams using Optimal Transport

NeurIPS 2018poster

Persistence diagrams (PDs) are now routinely used to summarize the underlying topology of complex data. Despite several appealing properties, incorporating PDs in learning pipelines can be challenging because their natural geometry is not Hilbertian. Indeed, this was recently exemplified in a string…
