Contrastive predictive coding for Anomaly Detection in Multi-variate Time Series Data

no code implementations8 Feb 2022 THEIVENDIRAM PRANAVAN, Terence Sim, ArulMurugan Ambikapathi, Savitha Ramasamy

Next, the latent representations for the succeeding instants obtained through non-linear transformations of these context vectors, are contrasted with the latent representations of the encoder for the multi-variables such that the density for the positive pair is maximized.

Identifiability of the Simplex Volume Minimization Criterion for Blind Hyperspectral Unmixing: The No Pure-Pixel Case

no code implementations20 Jun 2014 Chia-Hsiang Lin, Wing-Kin Ma, Wei-Chiang Li, Chong-Yung Chi, ArulMurugan Ambikapathi

In blind hyperspectral unmixing (HU), the pure-pixel assumption is well-known to be powerful in enabling simple and effective blind HU solutions.
