public class WalkForwardRequest
extends Object

Opt in to walk-forward validation. Present, the sweep runs as F sequential folds and the result gains a `walkForward` section; absent, nothing about the sweep changes. Two requests that differ only in this block are two different sweeps and do not deduplicate against each other.

Method Details

folds

public WalkForwardRequest folds(@Nonnull
 Integer folds)

getFolds

@Nonnull
public Integer getFolds()

How many sequential optimize-then-score windows to run. Two is the minimum for a reason, and it is structural rather than a tuning choice: parameter drift is measured between consecutive fold winners, and a single fold — one train/test split with no sequence — has no consecutive pair to compare, so it would report the strongest possible stability having measured nothing. The upper bound is a server setting (12 by default) and is deliberately not pinned here, since a spec that hardcodes a tunable limit lies the day it is raised. Exceeding it, or exceeding the sweep budget once multiplied by the grid size, is a 400. minimum: 2

Returns:

folds

setFolds

public void setFolds(@Nonnull
 Integer folds)

inSamplePct

public WalkForwardRequest inSamplePct(@Nullable
 Integer inSamplePct)

getInSamplePct

@Nullable
public Integer getInSamplePct()

Share of the session each fold spends optimizing; the remainder is where its winner is scored. Lower values leave more data to be scored on and, on short sessions, are also what lets the requested fold count tile the data at all. minimum: 10 maximum: 90

Returns:

inSamplePct

setInSamplePct

public void setInSamplePct(@Nullable
 Integer inSamplePct)

equals

public boolean equals(Object o)

Return true if this WalkForwardRequest object is equal to o.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

toString

public String toString()

Overrides:

toString in class Object

toUrlQueryString

public String toUrlQueryString()

Convert the instance into URL query string.

Returns:

URL query string

toUrlQueryString

public String toUrlQueryString(String prefix)

Convert the instance into URL query string.

Parameters:

prefix - prefix of the query string

Returns:

URL query string
