First steps with scikit-learn – training a perceptron

In Chapter 2, Training Simple Machine Learning Algorithms for Classification, you learned about two related learning algorithms for classification, the perceptron rule and Adaline, which we implemented in Python by ourselves. Now we will take a look at the scikit-learn API, which combines a user-friendly interface with a highly optimized implementation of several classification algorithms. The scikit-learn library offers not only a large variety of learning algorithms, but also many convenient functions to preprocess data and to fine-tune and evaluate our models. We will discuss this in more detail, together with the underlying concepts, in Chapter 4, Building Good Training Sets – Data Preprocessing ...
