Machine Learning Today Use slides from security class for pictures sometimes. How can a machine learn? Statistics, mostly Example with GNA, since we talked about it earlier Actual methods: A lot of these are inspired by something or other Neural networks, bayes rule, etc. Example of inspiration: Simulated annealing An optimization algorithm Real-world basis Problem formulation: How about a simple one? Classification Like the brain scan example Usually does come with a degree of confidence Generative AI doesn't seem to use this... Moving to my slides at this point
