mlcourse.ai – Open Machine Learning Course

mlcourse.ai is an open Machine Learning course by OpenDataScience. The course is designed to perfectly balance theory and practice. You can take part in several Kaggle Inclass competitions held during the course. From spring 2017 to fall 2019, 6 sessions of mlcourse.ai took place - 26k participants applied, 10k converted to passing the first assignment, about 1500 participants finished the course. Currently, the course is in self-paced mode. A thorough roadmap guiding you through the self-paced mlcourse.ai will be published in February, 2020.
