If you are intrested in a basic machine learning algorythms class, may I suggest Future Learns' online 5 week course:
Discover practical data mining and learn to mine your own data using the popular Weka workbench."
Some things that might make this useful to members of the Tessitura community:

This class is not available year round the best I can tell. However, I think it is still open for new students at this time.
If you decide to jump in please let me know.
