Who is Matthew Brand?

Matthew Brand is a scientist and artist based in Cambridge, Massachusetts. Brand's research focuses on mathematical and computational models of perception, learning, and control, in which each is treated as an optimization problem. He most widely cited for related inventions:

Specular holograms are three-dimensional images made of thousands of dots of light that glint off of finely carved metal or glass. The Museum of Mathematics in New York has a large art installation of specular holograms.

PQP is a method for solving very large convex optimization, particularly quadratic programming, in parallel. It enables real-time optimal control of extremely fast machinery.

Incremental singular value decomposition is method for finding and tracking the principal directions of variation in a high-dimensional data stream. It is widely used in large-scale data mining, including real-time seismic monitoring, analysis of consumer transactions, computer vision, natural language analysis, and machine learning.

Entropic estimation is a method for revising beliefs when faced with new data. It combines Bayes theorem and Occam's Razor to find a probabilistic model that minimizes the coding costs of both the data and the model, which in turn has high probability of generalizing correctly. It is a popular technique in the analysis of bioinformatic data.
