Tutorials

An Introduction to Vector Symbolic Architectures and Hyperdimensional Computing, ECAI 2020

We held a tutorial (tutorial website) on high dimensional computing at the 2020 European Conference on Artificial Intelligence (ECAI). We gave an introduction to properties of the high dimensional space, Vector Symbolic Architectures (VSAs), high-dimensional encoding of real world data, and applications. More information about the topic can be found in our recent journal article:
