My latest adventure into the world of online classes started today. I’ll be spending the next ten weeks completing, “CaltechX: CS1156x Learning From Data (introductory Machine Learning course).” This will be the first class that I have taken within the edX environment. I have heard good things about the platform and wanted to check it out firsthand. I figured I start with a challenging class about machine learning. The instructor estimates that the class will take about 10 hours of effort a week.
