Sometimes confused with linear regression by novices - due to sharing the term regression - logistic regression is far different from linear regression. While linear regression predicts values such as 2, 2.45, 6.77 or continuous values, making it a regression algorithm, logistic regression predicts values such as 0...
In this guide, we will focus on implementing the Hierarchical Clustering Algorithm with Scikit-Learn to solve a marketing problem. After reading the guide, you will understand: When to apply Hierarchical Clustering How to visualize the dataset to understand if it is fit for clustering How to pre-process features and engineer...
The Portable Document Format (PDF) is not a WYSIWYG (What You See is What You Get) format. It was developed to be platform-agnostic, independent of the underlying operating system and rendering engines. To achieve this, PDF was constructed to be interacted with via something more like a programming language, and...

In this guide, we'll dive into a dimensionality reduction, data embedding and data visualization technique known as Multidimensional Scaling (MDS). We'll be utilizing Scikit-Learn to perform Multidimensional Scaling, as it has a wonderfully simple and powerful API. Throughout the guide, we'll be using the Olivetti faces dataset from AT&...

This guide is an introduction to Spearman's rank correlation coefficient, its mathematical calculation, and its computation via Python's pandas library. We'll construct various examples to gain a basic understanding of this coefficient and demonstrate how to visualize the correlation matrix via heatmaps. What Is the Spearman Rank Correlation Coefficient? Spearman...
Matplotlib is one of the most widely used data visualization libraries in Python. Much of Matplotlib's popularity comes from its customization options - you can tweak just about any element from its hierarchy of objects. In this tutorial, we'll take a look at how to turn off a Matplotlib plot's...

Plotly is a JavaScript-based, Python data visualization library, focused on interactive and web-based visualizations. It has the simplicity of Seaborn, with a high-level API, but also the interactivity of Bokeh. In addition to the core library's functionality, using the built-in Plotly Express with Dash, makes it an amazing choice for...
