revanalyzer.vectorizers.direct_vectorizer.DirectVectorizer

class revanalyzer.vectorizers.direct_vectorizer.DirectVectorizer(norm=2)

Bases: BasicVectorizer

Class describing direct vectorizer.

Input:

norm (int): Norm of vectors used in REV analysis. The same, as parameter ‘ord’ in numpy.linalg.norm function, default: 2.

Methods

vectorize

Vectorize the vector metric values for a given pair of subsamples.

vectorize(v1, v2)

Vectorize the vector metric values for a given pair of subsamples.

Input:

v1 (list(dtype = float)): data for the first subsample;

v2 (list(dtype = float)): data for the second subsample.

Output:

(list(dtype = float), list(dtype = float), float) - a tuple, in which the first two elements are vectorized metric values for a given pair of subsamples, and the last one is the normalized distance between these vectors.
