Scikit-Learn is a powerful library that provides a handful of supervised and unsupervised learning algorithms. If you’re serious about having a career in machine learning, then scikit-learn is a must know.

In this course, you will start by learning the various built-in datasets that scikit-learn offers, such as iris and mnist. You will then learn about feature engineering and more specifically, feature selection, feature extraction, and dimension reduction.

In the latter half of the course, you will dive into linear and logistic regression where you’ll work through a few challenges to test your understanding. Lastly, you will focus on unsupervised learning and deep learning where you’ll get into k-means clustering and neural networks.

By the end of this course, you will have a great new skill to add to your resume, and you’ll be ready to start working on your own projects that will utilize scikit-learn.

Hands-on Machine Learning with Scikit-Learn

In this lesson, we cover the topic of datasets. A dataset is an essential part of the process of Machine Learning projects because it is the starting point for a project.

The **scikit-learn** library has many built-in datasets, some well-known and widely used. For example, it has the *iris* and *mnist* datasets for classification and the *boston* house price for regression. In addition to these predefined datasets, **scikit-learn** provides other functions that can generate some data that follows certain distributions.

Meanwhile, **scikit-learn** pre-defines some functions that can download real-world datasets from the internet, such as `20 newsgroups`, `LFW`, or `KDDcup99` datasets.

All datasets are in the module `datasets`. Import this module at the beginning of your Python file as below.

```python
import sklearn.datasets as datasets
```

In this lesson, we'll see how to load the built-in datasets and create data based on certain distributions.
