The IncrementalInterpolate operator calculates missing values in a time series.
KMeansClustering
Cluster analysis is a popular technique used to find natural grouping of a set of objects.
Kalman
The Kalman operator runs an adaptive filter on a time series and can used for tracking, smoothing, adaptation.
LPC
The Linear Predictive Coding (LPC) operator uses an autoregressive (AR) model to predict values in a time series.
Normalize
The Normalize operator incrementally estimates the means and variance and can normalize the time series to zero means and unit variance.
PSAX
The PSAX operator is capable of providing a symbolic representation of real-valued time series data.
RLSFilter
The Recursive Least Squares (RLS) is linear regression estimation algorithm that learns to predict a target time series, given inputs.
