Once we have this running, we can scale it out to use it in real development scenarios in the following examples. Let's start small and build it up from there. First, we need to create a simple Co...
Suppose you need to work on three different projects project A, project B and project C. project A and project B need python 3 and some required libraries.

Supervised learning is a type of machine learning algorithm that uses a known data-set (called the training data-set) to make predictions. Category of supervised learning: Regression: In a regression problem, we are trying to predict results within a continuous output, meaning that we are trying...
Unsupervised learning allows us to approach problems with little or no idea what our results should look like. We can derive structure from data where we don't necessarily know the effect of the variables. Example: Clustering: Is used for exploratory data analysis to find hidden patterns or groupi...
