Introduction

Both machine learning (ML) and artificial intelligence (AI) are fundamental parts of humanity’s quest to develop brilliant, self-educating, learning machines.

What is Git?

Git is the most commonly used VCS (Version Control System) today. Git is a free distributed version control system used for tracking changes in source code during development. It is installed and maintained on your local system. It is designed mainly for orchestrating work among developers. But, it can also be used for tracking changes in any set of files.

What is Jupyter Notebook?

Jupyter Notebook is an extremely powerful open-source, web-based tool that facilitates the creation of documentation. There are many different avenues to provide technical documentation or demonstrations, but Jupyter Notebook makes it possible to embed visualizations and execute live code. It is useful to be able to utilize documentation to describe development concepts or planning, but providing working examples within documentation can be a more effective way of conveying information. This tutorial will cover how to install Jupyter Notebook on an Ubuntu 18.04 LTS server and connect to it remotely via an SSH tunnel.

What is Elasticsearch?
