R&D Activities at Machine Learning and Data Science Center▼Abstract

The Machine Learning and Data Science Center (MLC) wasestablished in April 2013 as a research and development hub of big
data analysis technologies at NTT laboratories with the aim of creating
innovative services from a wide variety of big data. MLC uses machinelearning and data mining technologies cultivated by NTT laboratories
and a parallel-distributed processing platform (Jubatus) for high-efficiency and real-time data analysis todevelop diverse big data analysis technologies and support big data services. This article introduces thesebig data activities at MLC.
