I did part of the ML course. I've been pondering over which language to choose to advance my functional programming journey. I've been torn between choosing Lispy variants such as Scheme, Racket, Clojure etc or the ML variants such Scala, SML, OCaml, F# or go nuts and do Haskell! :D But I'm a data analyst by profession and I'm 35 years old. So I need to choose something wisely. I'm studying statistics at the moment and the most wise choice for me is R. I already do some work on Python. R is based on Scheme and has a lot of functional aspects. Some of the answers related to Machine Learning here are relevant to me. But for the question, I also believe the Washington University course is a strong contender. Hopefully, I'll have the time in future to learn some of it.
