Welcome at the Research Group Digital Mathematics (DIMA) which is affiliated with the VUB AI Lab.

DIMA specializes in mathematics for digital data science. The word "digital" is derived from the Latin word "digitus" and hence refers to finger-counting used to enumerate objects. Data or mathematical techniques that are represented by a discrete number of values are therefore called "digital". We focus in particular on the mathematical foundations for digital data modelling, analysis and (secure) communication.
