Unexplainable Explanations: Towards Interpreting tSNE and UMAP Embeddings

no code implementations20 Jun 2023 Andrew Draganov, Simon Dohn

It has become standard to explain neural network latent spaces with attraction/repulsion dimensionality reduction (ARDR) methods like tSNE and UMAP.

ActUp: Analyzing and Consolidating tSNE and UMAP

1 code implementation12 May 2023 Andrew Draganov, Jakob Rødsgaard Jørgensen, Katrine Scheel Nellemann, Davide Mottin, Ira Assent, Tyrus Berry, Cigdem Aslay

tSNE and UMAP are popular dimensionality reduction algorithms due to their speed and interpretable low-dimensional embeddings.

ChaRRNets: Channel Robust Representation Networks for RF Fingerprinting

no code implementations8 May 2021 Carter N. Brown, Enrico Mattei, Andrew Draganov

We introduce the Lie group of transformations that a signal experiences under the multipath propagation model and define operations that are equivariant and invariant to the frequency response of a Finite Impulse Response (FIR) filter to build a ChaRRNet.
