This Machine Learning tutorial introduces the basics of ML theory, laying down the common themes and concepts, making it easy to follow the logic and get comfortable with the topic. In our employee satisfaction example, the well-established standard is the linear least squares function: With least squares, the penalty for a bad guess goes up quadratically with the difference between the guess and the correct answer, so it acts as a very “strict” measurement of wrongness. We can then tweak h(x) by tweaking the values of and to make it “less wrong”. __________________________________________________________________________. Yeah, looks like its summarize of first four weeks of Andrew Ng lessons. This process of alternating between calculating the current gradient, and updating the s from the results, is known as gradient descent. In classification, a regression predictor is not very useful.
