ott.geometry.costs.SqPNorm#
- class ott.geometry.costs.SqPNorm(p)[source]#
Squared p-norm of the difference of two vectors.
- Parameters:
p (
float) – Power of the p-norm, \(\ge 1\).
Methods
all_pairs(x, y)Compute matrix of all pairwise costs, including the
norms.all_pairs_pairwise(x, y)Compute matrix of all pairwise costs, excluding the
norms.barycenter(weights, xs)Barycentric operator.
h(z)TI function acting on difference of \(x-y\) to output cost.
h_legendre(z)Legendre transform of
h().pairwise(x, y)Compute cost as evaluation of
h()on \(x-y\).Attributes
