@srniranjan I don't know of any reading groups. A quick Google search shows various initiatives, but they aren't active anymore. Feel free to share your progress if you're continuing to read it! I've tried for years to read it and making time to casually read it now.
@srniranjan you may find it easier to read the Introduction to Statistical Learning book by some of the same authors of the EoSL book. It has less mathy language, R code to implement the algorithms, and also free online.
