Padding a number with zeros can be needed for a few reasons, whether it's to make a number look more readable, to make a numeric string easier to sort in a list, or in low-level binary protocols that require packets to be a certain length. The most obvious way to...

String manipulation is a common task in many languages, especially when creating user interfaces. One of the most common tasks is to concatenate a string and an integer together. Here we'll show you a few different ways to achieve this in Python. Using the + operator, we can add a string...
Agglomerative Hierarchical Clustering is an unsupervised learning algorithm that links data points based on distance to form a cluster, and then links those already clustered points into another cluster, creating a structure of clusters with sub-clusters. It is easily implemented using Scikit-Learn which already has single, average, complete and ward...

Regression is a technique in statistics and machine learning, in which the value of an independent variable is predicted by its relationship with other variables. Frameworks like Scikit-Learn and XGBoost make it easier than ever to perform regression with a wide variety of models - one of the recently well-adopted...

Saving and loading Scikit-Learn models is part of the lifecycle of most models - typically, you'll train them in one runtime and serve them in another. In this Byte - you'll learn how to save and load a regressor using Scikit-Learn. First off, let's build a simple regressor and fit...
So - you've trained a sparkling regressor using XGBoost! Which features are the most important in the regression calculation? The first step in unboxing the black-box system that a machine learning model can be is to inspect the features and their importance in the regression. Let's quickly train a mock...
RandomizedSearchCV and GridSearchCV allow you to perform hyperparameter tuning with Scikit-Learn, where the former searches randomly through some configurations (dictated by n_iter) while the latter searches through all of them. XGBoost is an increasingly dominant library, whose regressors and classifiers are doing wonders over more traditional implementations, and is...
Scikit-Learn's scalers are the backbone of practically all regressors and classifiers built on top of them, scaling the data to a workable range and preparing a latent representation to learn from. If you'd like to read more about feature scaling, read our "Feature Scaling Data with Scikit-Learn for Machine...
