Aki Ariga

Field Data Scientist at Cloudera.

I’m interested in natural language processing and machine learning, and applying those technologies in production. I love to think how leverage data with technology for bussiness. I also love to write Ruby, Python and Julia for ML.

I am a podcaster of technical podcast rubyist.club.
