MANTRA: The Manifold Triangulations Assemblage

1 code implementation3 Oct 2024 Rubén Ballester, Ernst Röell, Daniel Bin Schmid, Mathieu Alain, Sergio Escalera, Carles Casacuberta, Bastian Rieck

The rising interest in leveraging higher-order interactions present in complex systems has led to a surge in more expressive models exploiting high-order structures in the data, especially in topological deep learning (TDL), which designs neural networks on high-order domains such as simplicial complexes.

Topological Deep Learning seeks to enhance the predictive performance of neural network models by harnessing topological structures in input data.

Topological Data Analysis for Neural Network Analysis: A Comprehensive Survey

no code implementations10 Dec 2023 Rubén Ballester, Carles Casacuberta, Sergio Escalera

We discuss different strategies to obtain topological information from data and neural networks by means of TDA.

Decorrelating neurons using persistence

1 code implementation9 Aug 2023 Rubén Ballester, Carles Casacuberta, Sergio Escalera

We propose a novel way to improve the generalisation capacity of deep learning models by reducing high correlations between neurons.

On the Expressivity of Persistent Homology in Graph Learning

no code implementations20 Feb 2023 Rubén Ballester, Bastian Rieck

Persistent homology, a technique from computational topology, has recently shown strong empirical performance in the context of graph classification.
