What are the phases of anomaly detection?
The algorithm for anomaly detection is decomposed in two phases : a learning phase (top) for the model and the distribution, and a test phase (bottom) to evaluate the performance of the algorithm. The red parts are the elements from the learning phase that are used during the test phase.
What is time series anomaly detection?
Time series analysis is a very useful and powerful technique for studying data that changes over time, such as sales, traffic, climate, etc. Anomaly detection is the process of identifying values or events that deviate from the normal trend of the data.
