On the Role of Noise in Factorizers for Disentangling Distributed Representations

Geethan Karunaratne, Michael Hersche, Abu Sebastian +1

To efficiently factorize high-dimensional distributed representations to the constituent atomic vectors, one can exploit the compute-in-superposition capabilities of vector-symboli…

Zero-shot Classification using Hyperdimensional Computing

Samuele Ruffino, Geethan Karunaratne, Michael Hersche +3

Classification based on Zero-shot Learning (ZSL) is the ability of a model to classify inputs into novel classes on which the model has not previously seen any training examples. P…

Wireless On-Chip Communications for Scalable In-memory Hyperdimensional Computing

Robert Guirado, Abbas Rahimi, Geethan Karunaratne +3

Hyperdimensional computing (HDC) is an emerging computing paradigm that represents, manipulates, and communicates data using very long random vectors (aka hypervectors). Among diff…
