Starting from March 30, every Wednesday, Nikolay Pavlov, Data Scientist @ Azzurro.io, will hold a series of Data Analysis with R workshops, reports the IP-portal DOU.UA.
Data Analysis with R includes eight 2-hour sessions dedicated to Data Science.
Participants of the workshops will be able to learn about functional programming (Scala) and machine learning (R&Spark) absolutely free.
Organizer of training – Kharkiv Computer Science Group and the informal association of R&D companies and individual researchers.
