MultivariateGaussian
(mean: pyspark.ml.linalg.Vector, cov: pyspark.ml.linalg.Matrix)¶ Represents a (mean, cov) tuple
Examples
>>> from pyspark.ml.linalg import DenseMatrix, Vectors >>> from pyspark.ml.stat import MultivariateGaussian >>> m = MultivariateGaussian(Vectors.dense([11,12]), DenseMatrix(2, 2, (1.0, 3.0, 5.0, 2.0))) >>> (m.mean, m.cov.toArray()) (DenseVector([11.0, 12.0]), array([[ 1., 5.], [ 3., 2.]]))
