Features
- bayesianRegression (Stream Processor)
This extension predicts using a Bayesian linear regression model.Bayesian linear regression allows determining the uncertainty of each prediction by estimating the full-predictive distribution
- kMeansIncremental (Stream Processor)
Performs K-Means clustering on a streaming data set. Data points can be of any dimension and the dimensionality is calculated from number of parameters. All data points to be processed by a query should be of the same dimensionality. The Euclidean distance is taken as the distance metric. The algorithm resembles Sequential K-Means Clustering at https://www.cs.princeton.edu/courses/archive/fall08/cos436/Duda/C/sk_means.htm
- kMeansMiniBatch (Stream Processor)
Performs K-Means clustering on a streaming data set. Data points can be of any dimension and the dimensionality is calculated from number of parameters. All data points to be processed in a single query should be of the same dimensionality. The Euclidean distance is taken as the distance metric. The algorithm resembles mini-batch K-Means. (refer Web-Scale K-Means Clustering by D.Sculley, Google, Inc.).
- perceptronClassifier (Stream Processor)
This extension predicts using a linear binary classification Perceptron model.
- updateBayesianRegression (Stream Processor)
This extension builds/updates a linear Bayesian regression model. This extension uses an improved version of stochastic variational inference.
- updatePerceptronClassifier (Stream Processor)
This extension builds/updates a linear binary classification Perceptron model.
Dependencies
There are no other dependencies needed for this extension.
