I think your post may have more acronyms than any other post I have ever read on hn. Do you have a guide to which specific things you are talking about with each acronym? Deep Learning and Machine Learning are obvious but some of the others I can’t follow at all - they could be so many different things.
NN - neural networks OSS DL frameworks - open source deep learning frameworks
PITA - pain in the ass
SVM - support vector machines HMM - hidden Markov model EM - expectation maximization GMM - gaussian mixture model HTK - hidden Markov model tool kit
