RiskSplitCounts class

Constructors

RiskSplitCounts({int? judged, int? productive, int? rows, int? subjects, int? test, int? train, int? unproductive, int? val})

Returns a new RiskSplitCounts instance.

Properties

hashCode → int

The hash code for this object.

no setter, override

judged ↔ int?

Judged is how many rows carry a disposition. It is zero until a label plane writes one, and reporting it plainly is what lets a model plane refuse to rank rather than name a winner it cannot justify.

getter/setter pair

productive ↔ int?

Productive is how many judged rows carry the one disposition.

getter/setter pair

rows ↔ int?

Rows is how many rows the version holds across every split. It is the size of the version, not of the source window — the horizon, the cuts and the row cap all bind before this number.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

subjects ↔ int?

Subjects is how many distinct subjects the rows belong to. Every row of one subject is in ONE split, so this is the real sample size — the row count flatters it whenever a subject is active.

getter/setter pair

test ↔ int?

Test is how many fall after the second cut — the LATEST slice, and the only one a score is honest about, since the split is temporal.

getter/setter pair

train ↔ int?

Train is how many rows fall before the first cut — the EARLIEST slice of the window, which is what a model is fitted on.

getter/setter pair

unproductive ↔ int?

Unproductive is how many carry the other. With Productive it accounts for Judged, so the class imbalance is visible before anyone trains on it; both stay 0 while Judged is 0.

getter/setter pair

val ↔ int?

Val is how many fall between the two cuts, held out for tuning.

getter/setter pair

Methods

noSuchMethod(Invocation invocation) → dynamic

inherited

toJson() → Map<String, dynamic>

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

fromJson(dynamic value) → RiskSplitCounts?

Returns a new RiskSplitCounts instance and imports its values from value if it's a Map, null otherwise.

listFromJson(dynamic json, {bool growable = false}) → List<RiskSplitCounts>

mapFromJson(dynamic json) → Map<String, RiskSplitCounts>

mapListFromJson(dynamic json, {bool growable = false}) → Map<String, List<RiskSplitCounts>>

Constants

requiredKeys → const Set<String>

The list of required keys that must be present in a JSON.
