Enum AbortStrategy 

pub enum AbortStrategy<T: Primitive> {
    NoImprovement {
        threshold: T,
    },
    NoImprovementForXIterations {
        x: usize,
        threshold: T,
        abort_on_negative: bool,
    },
}

Enum with possible abort strategies. These strategies specify when a running iteration (with the k-means calculation) is aborted.

Variants

NoImprovement

This strategy aborts the calculation directly after an iteration produced no improvement where improvement > threshold for the first time.

Fields:

• threshold: Threshold, used to detect an improvement (improvement > threshold)

Fields

threshold: T

NoImprovementForXIterations

This strategy aborts the calculation, when there have not been any improvements after x iterations, where improvement > threshold.

Fields:

• x: The amount of consecutive without improvement, after which the calculation is aborted
• threshold: Threshold, used to detect an improvement (improvement > threshold)
• abort_on_negative: Specifies whether the strategy instantly aborts when a negative improvement occured (true), or if negative improvements are handled as “no improvements” (false).

Fields

x: usize

threshold: T

abort_on_negative: bool
