The Infosys Foundation and the Association for Computing Machinery, the prestigious computing science society, has announced the ACM-Infosys Foundation Award for 2013 in computing sciences.

David Blei, an expert in machine learning, known for his work in ‘topic modelling’, a technique to organise and summarise digital archives, was chosen for the award, a release stated.

An associate professor at Princeton University’s Department of Computer Science, Prof. Blei’s research led to a topic model called the LDA (latent dirichlet allocation), which is a tool for discovering hidden semantic themes in large data troves. His approach to analysing large data collections is scalable to collections that include billions of documents.

The award recognises young scientists and system developers in the computing field and the Infosys Foundation’s endowment provides financial support worth $1,75,000.
