ETH-tight algorithms for finding surfaces in simplicial complexes of bounded treewidth
Mitchell Black, Nello Blaser, Amir Nayyeri +1
Given a simplicial complex with simplices, we consider the Connected Subsurface Recognition (c-SR) problem of finding a subcomplex that is homeomorphic to a given connected sur…
Homology Localization Through the Looking-Glass of Parameterized Complexity Theory
Nello Blaser, Erlend Raa Vågset
Finding a cycle of lowest weight that represents a homology class in a simplicial complex is known as homology localization (HL). Here we address this NP-complete problem using par…
Semi Conditional Variational Auto-Encoder for Flow Reconstruction and Uncertainty Quantification from Limited Observations
Kristian Gundersen, Anna Oleynik, Nello Blaser +1
We present a new data-driven model to reconstruct nonlinear flow from spatially sparse observations. The model is a version of a conditional variational auto-encoder (CVAE), which…
Sparse Nerves in Practice
Nello Blaser, Morten Brun
Topological data analysis combines machine learning with methods from algebraic topology. Persistent homology, a method to characterize topological features occurring in data at mu…
Sparse Filtered Nerves
Nello Blaser, Morten Brun
Given a point cloud in Euclidean space and a positive parameter we can consider the -neighborhood of consisting of points at distance less than to . H…
