Disentanglement Learning via Topology

no code implementations24 Aug 2023 Nikita Balabin, Daria Voronkova, Ilya Trofimov, Evgeny Burnaev, Serguei Barannikov

We propose TopDis (Topological Disentanglement), a method for learning disentangled representations via adding multi-scale topological loss term.

Learning Topology-Preserving Data Representations

1 code implementation31 Jan 2023 Ilya Trofimov, Daniil Cherniavskii, Eduard Tulchinskii, Nikita Balabin, Evgeny Burnaev, Serguei Barannikov

The method aims to provide topological similarity between the data manifold and its latent representation via enforcing the similarity in topological features (clusters, loops, 2D voids, etc.)

Topological obstructions in neural networks learning

no code implementations31 Dec 2020 Serguei Barannikov, Daria Voronkova, Ilya Trofimov, Alexander Korotin, Grigorii Sotnikov, Evgeny Burnaev

We define the neural network Topological Obstructions score, "TO-score", with the help of robust topological invariants, barcodes of the loss function, that quantify the "badness" of local minima for gradient-based optimization.
