Time series class prototype generation for classification with DBA Time series classification is an important task in many fields, such as finance, healthcare, and meteorology. A common approach to time series classification is to use class prototypes generated by a time series “averaging algorithm”. Each of the classes is represented by a class prototype, which is typically the "average" time series for that cluster. These class prototypes can then be used to classify new time series data. In this post, we will explore the use of class prototypes for time series classification and discuss some of the advantages and challenges of this approach.
