Loading datasets using Python
Introduction Before we proceed with either kind of machine learning problem, we need to get the data on which we'll operate. We can of course generate data by hand, but this course of action won't get us far as is too tedious and lacks the diversity we may require. The are numerous sources of real data we can use and if none of it satisfies ones needs, there are some popular artificial generators, creating datasets according to preset parameters. scikit-learn provides a plenty of methods to load and fetch popular datasets as well as generate artificial data. All these can be found in sklearn.datasets package. Toy Datasets The scikit-learn embeds some small toy datasets, which provide data scientists a playground to experiment a new algorithm and evaluate the correctness of their code before applying it to a real world sized data. Let's load and render one of the most common datasets - iris dataset import numpy as np import matplotlib.pyplot as plt from sklea
