LOCA: LOcal Conformal Autoencoder for standardized data coordinates

no code implementations15 Apr 2020 Erez Peterfreund, Ofir Lindenbaum, Felix Dietrich, Tom Bertalan, Matan Gavish, Ioannis G. Kevrekidis, Ronald R. Coifman

We propose a deep-learning based method for obtaining standardized data coordinates from scientific measurements. Data observations are modeled as samples from an unknown, non-linear deformation of an underlying Riemannian manifold, which is parametrized by a few normalized latent variables.

Weakly Supervised Indoor Localization via Manifold Matching

no code implementations7 Feb 2022 Erez Peterfreund, Ioannis G. Kevrekidis, Ariel Jaffe

Inferring the location of a mobile device in an indoor setting is an open problem of utmost significance.

Gappy local conformal auto-encoders for heterogeneous data fusion: in praise of rigidity

no code implementations20 Dec 2023 Erez Peterfreund, Iryna Burak, Ofir Lindenbaum, Jim Gimlett, Felix Dietrich, Ronald R. Coifman, Ioannis G. Kevrekidis

Fusing measurements from multiple, heterogeneous, partial sources, observing a common object or process, poses challenges due to the increasing availability of numbers and types of sensors.
