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...

Converting an object into a saveable state (such as a byte stream, textual representation, etc) is called serialization, whereas deserialization converts data from the aforementioned format back to an object. A serialized format retains all the information required to reconstruct an object in memory, in the same state as it...

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...
