One-Class Support Vector Machine:
Anomaly Detection
Creates a one-class support vector machine model for anomaly detection.
This module is particularly useful in scenarios where you have a lot of “normal” data and not many cases of the anomalies you are trying to detect. For example, if you need to detect fraudulent transactions, you might not have many examples of fraud that you could use to train a typical classification model, but you might have many examples of good transactions.
You use the One-Class Support Vector Model module to create the model, and then train the model using the Train Anomaly Detection Model. The dataset that you use for training can contain all or mostly normal cases.
You can then apply different metrics to identify potential anomalies. For example, you might use a large dataset of good transactions to identify cases that possibly represent fraudulent transactions.
PCA-Based Anomaly Detection:
Anomaly Detection
Creates an anomaly detection model by using Principal Component Analysis.
This module helps you build a model in scenarios where it is easy to obtain training data from one class, such as valid transactions, but difficult to obtain sufficient samples of the targeted anomalies.
For example, to detect fraudulent transactions, very often you don’t have enough examples of fraud to train on, but have many examples of good transactions. The PCA-Based Anomaly Detection module solves the problem by analyzing available features to determine what constitutes a “normal” class, and applying distance metrics to identify cases that represent anomalies. This let you train a model using existing imbalanced data.
