Machine learning is quickly becoming the most sought after skill in the job market. Specifically, employers are looking for candidates with experience in scikit-learn, the most popular ML Python library. Scikit-learn is a library for Python that provides machine learning developers with many unsupervised and supervised learning algorithms.
Today, we’ll explore this awesome library and show you how to implement its core functions. At the end, we’ll combine what we’ve learned to implement your own linear regression algorithm.
Here’s what we’ll cover today:
Scikit-learn (or sklearn for short) is a free open-source machine learning library for Python. It’s designed to cooperate with SciPy and NumPy libraries and simplifies data science techniques in Python with built-in support for popular classification, regression, and clustering machine learning algorithms.
Sklearn serves as a unifying point for many ML tools to work seamlessly together. It also gives data scientists a one-stop-shop toolkit to import, preprocess, plot, and predict data.
The project was started by David Cournapeau during the 2007 Google Summer of Code, and this library has grown over the last decade in both popularity and features. Scikit-learn is now the most popular machine learning library on Github.
Scikit-learn provides tools for:
Developers and machine learning engineers use Sklearn because:
Scikit-learn is a toolkit to expand the functions of the existing SciPy Stack (sometimes called the NumPy Stack). Below, we outline how Scikit-learn uses each library within the SciPy stack for data analysis.
