swarmauri_standard.seminorms.PartialSumSeminorm.PartialSumSeminorm

PartialSumSeminorm(
    start_idx=None, end_idx=None, indices=None, **kwargs
)

Bases: SeminormBase

Seminorm computed via summing only part of the vector.

This seminorm evaluates the norm on a partial segment of the input, ignoring the rest. It is particularly useful when only specific elements of a vector or matrix are relevant for a given analysis.

Attributes

type : Literal["PartialSumSeminorm"] The type identifier for this seminorm start_idx : Optional[int] Starting index for the summation (inclusive) end_idx : Optional[int] Ending index for the summation (exclusive) indices : Optional[Sequence[int]] Specific indices to include in the summation

Initialize the PartialSumSeminorm.

Parameters

start_idx : Optional[int], optional Starting index for the summation (inclusive), by default None end_idx : Optional[int], optional Ending index for the summation (exclusive), by default None indices : Optional[Sequence[int]], optional Specific indices to include in the summation, by default None

Notes

Either provide start_idx and end_idx to define a range, or provide indices to specify exact elements to include.
