Self-education
The web is a great place for expanding knowledge and online courses can be a good way of getting quick introduction to the subject. I try to keep myself updated with interesting technical things by taking online classes from time to time using platforms like coursera.

The classes I have learnt from include:

  • University College London course on Reinforcement Learning.
  • IBM Cognitive class on Python for Data Science.
  • IBM Cognitive class on Machine Learning with Python.
