Isolation Forest: A Tree based approach for Outlier Detection (Clearly Explained)

YouTube • August 16, 2023 • 18:02

Welcome to the fifteenth video of the series "Build your First Machine Learning Project". In this, we'll see Isolation Forest Algorithm for outlier detection. Isolation Forest is a simple yet incredible algorithm that is able to spot outliers or anomalies in the data. Let's understand how the Isolation forest algorithm for Outlier detection ...

Introduction to Isolation Forest

YouTube • September 9, 2022 • 02:39

Isolation Forest is an ensemble of decision tree and is used to identify anomaly.It is an unsupervised machine learning model which works on the principle that there are fewer anomalous points in comparison to normal points and hence it is easier for the decision tree to branch normal observations.Due to this, the outliers/anomalous points are ...

Isolation Forests: Identify Outliers in Data

YouTube • March 7, 2023 • 04:41

In this video, senior data scientist Jericho McLeod walks us through an anomaly detection method called Isolation Forests. He demonstrates how to use the technique to quickly and accurately identify outliers by isolating data points. This method has many advantages, including its speed, ability to generalize, and low memory usage. Transcript ...

Isolation Forest for Outlier Detection within Python

YouTube • October 12, 2022 • 14:40

Isolation Forest is a popular unsupervised machine learning algorithm for detecting anomalies (outliers) within datasets. Anomaly detection is a crucial part of any machine learning and data science workflow. Erroneous values that are not identified early on can result in inaccurate predictions from machine learning models, and therefore impact ...

Explaining Anomalies with Isolation Forest and SHAP | Python Tutorial
