This tutorial is divided into four parts; they are: 1. Then if I pick the weighted die, I’ll have to roll it a few times to convince myself it’s the weighted on, but if I pick the unweighted one, I’ll convince myself it’s that one in many fewer rolls (if I only need to be 2-sigma confident, probably in 1 roll). Probability and statistics help us to understand and quantify the expected value and variability of variables in our observations from the domain. We can plug in the occurrence of each class (0.25 and 0.75) and the predicted probability for each class (0.5 and 0.5) and estimate the performance of the model. Because algorithms are such a big part of machine learning you must spend time to get familiar with them and really understand how they work. Running the example fits the model on the training dataset, then makes predictions for the same first example that we used in the prior example.

Edition: v1.4. We may be interested in the probability of an event for one random variable, irrespective of the outcome of another random variable. With a solid foundation of what probability is, it is possible to focus on just the good or relevant parts. It turns out that this classifier is pretty poor. It plays a central role in machine learning, as the design of learning algorithms often relies on proba- bilistic assumption of the data. In the next lesson, you will discover metrics for scoring models that predict probabilities.
