It’s better to be late, than to miss amazing opportunite to take part in not-official, but supervised online course of Deep Learning by CMU.

Course has already started, but you still can hop on the departing train to learn (or review) deep learning foundations and have some practice.

Content, quizes, practice exercises are in English.

This initiative was brought by editor of russian-speaking @powerofdata channel.
