We are the Data Analytics subgroup of the Chelmsford, MA Technical Skills Share Group (TSSG). We're a group of professionals in the Chelmsford area learning Big Data, Hadoop and Machine Learning. We meet weekly and work through various hands-on projects. Earlier project notes are attached to the Data Analytics section of the TSSG members-only wiki.

We meet during the TSSG general meeting every Wednesday at the Acton or Chelmsford (4th Wed. of month) Library for a status meeting. We have working meetings every Friday, 1:00 PM - 3:00 PM, at the Acton library. ... Updated October 2017.

We have studied Natural Language Processing and have a github project and NLP wiki.
