Data Mining Technology Group

The Data Mining Technology Group in NEC Data Science Research Laboratories
is trying to realize a brighter world using data analytics.

Our purpose is to predict the future and optimize an entire society based on data accumulated in the real world.
We are developing data analytics technologies by using mathematical techniques such as machine learning, statistics and optimization, and are conducting commercialization of those technologies.
