circle_bundles.EuclideanMetric

class circle_bundles.EuclideanMetric(name='euclidean')

Bases: object

Standard Euclidean metric on \(\mathbb{R}^d\).

This metric computes ordinary Euclidean distances between vectors using the ℓ² norm.

It is the default metric used throughout the library whenever no other metric is specified.

Parameters:

name (str)

name

Display name for the metric (default "euclidean").

Type:

str

__init__(name='euclidean')

Parameters:

name (str)

Return type:

None

Methods

__init__([name])
pairwise(X[, Y])	Compute Euclidean pairwise distances.

Attributes

name

pairwise(X, Y=None)

Compute Euclidean pairwise distances.

Parameters:

• X (ndarray) – Array of shape (n, d) or (n,) representing n points.

• Y (ndarray | None) – Optional array of shape (m, d) or (m,). If omitted, uses X.

Returns:

Euclidean distance matrix of shape (n, m).

Return type:

D
