WebbClassification algorithms are supervised learning methods to split data into classes. They can work on Linear Data as well as Nonlinear Data. Logistic Regression can classify data based on weighted parameters and sigmoid conversion to calculate the probability of classes. K-nearest Neighbors (KNN) algorithm uses similar features to classify data. WebbLooking at these time series, there are certainly many distinct shapes for a single day. Some look sinusoidal, some are constant, some look like a random stochastic process, …
