scikit-learn

A popular supervised classification algorithm used within scikit-learn is Support Vector Machine (SVM) SVM works by finding a hyperplane (a decision boundary) that separates data points from different classes. It does this by maximizing the distance (margin) between the hyperplane and the nearest data points from each class, which are called support vectors If you […]

In this Machine Learning lesson we are going to explore the Naive Bayes. An algorithm that is commonly used within Sci-kit learn. It’s a quite simple algorithm to use and we will practice using it on a dataset predicting if a concert sells out. Before we jump into this lesson though, I did want to […]

This beginner Scikit-learn lesson will cover multiple linear regressions.  This is when there is a relationship between the target (dependent variable) and two or more features (independent variables). If you’d like to watch a video that this tutorial is based on, it’s embedded down below. https://youtu.be/R2Zb5s_RrDU Let’s start by importing in everything we need for […]

Train Test Split is an important concept that future Data Scientists or Machine Learning Engineers need to pick up early on. When building models, you’ll want to split your data into two different sets. One for training a model, and one for testing a model. This article is based on the popular YouTube video on […]

Comprehensive Understanding to K-Nearest Neighbors (KNN) in Supervised Machine Learning. K-Nearest Neighbors (KNN) is a simple, widely used supervised learning algorithm in data science and machine learning It was developed by Evelyn Fix and Joseph Hodges in 1951. Known for it usefulness and versatality, KNN can handle both classification and regression tasks when needed. https://youtu.be/Nz73vXn5afE […]

Optuna is a hyperparameter optimization framework for machine learning models. It can help automate and streamline the process of tuning the hyperparameters. It’s quite popular among Kaggle users and you’ll see it used within competitions. In this article, we will go over an example of using it on a basic dataset. There is also a […]

When working with real world data, you’ll often have to deal with categorical information. This can be a problem when working with Machine Learning models as most cannot use it. Instead, Data Scientists and Machine Learning engineers need to convert this into a numerical format. This is where the Ordinal Encoder in Scikit-Learn can help. […]

In the realm of machine learning and data science, preparing your data is often as crucial as the modeling itself. One of the essential preprocessing steps when working with categorical data is one-hot encoding. This technique transforms categorical variables into a format that can be provided to machine learning algorithms to improve predictions and insights. […]
