Machine learning post roundup

Ugh, I've been falling behind in blogging out the links lately.  Here are a few things I've run across having to do with machine learning, NLP, and neural networks lately (all the stuff people don't call AI any more):

• Ersatz is an upcoming platform for neural network training in the cloud.  Neat!
• Topology optimization for physical structures with genetic programming, with a fun animation
• A CMU class in ML
• Sentiment analysis in Python
• A field guide to genetic programming, nice name
  
  And finally, an interesting post about the background:
• Prognistication about the future of the ML industry
