How can clustering be applied in anomaly detection?
Step 1: Gather your data that you want to analyze for anomalies.
Step 2: Choose a clustering algorithm (like K-means or DBSCAN) to group similar data points together.
Step 3: Run the clustering algorithm on your data to create clusters.
Step 4: Analyze the clusters to see how many data points are in each one.
Step 5: Identify data points that are far away from any cluster or belong to very small clusters.
Step 6: Mark these far-away points as anomalies since they do not fit well with the rest of the data.
Clustering – A method of grouping data points into clusters based on similarity, where points in the same cluster are more similar to each other than to those in other clusters.
Anomaly Detection – The process of identifying data points that deviate significantly from the majority of the data, often referred to as outliers.
Outliers – Data points that do not conform to the expected pattern of the data, often identified as those that are distant from the nearest cluster.
