ANN class

Constructors

ANN({required List<int> layers, int epochs = 100, double lr = 0.01, int? seed})

Properties

biases ↔ List<List<double>>

getter/setter pair

epochs → int

final

hashCode → int

The hash code for this object.

no setter, inherited

lastLoss ↔ double?

getter/setter pair

layers → List<int>

final

lossHistory → List<double>

history of loss values (one entry per epoch)

final

lr → double

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

weights ↔ List<List<List<double>>>

getter/setter pair

Methods

applyParamsFrom(ANN other) → void

fit(List<List<double>> X, List<List<double>> Y, {int? batchSize, bool verbose = false, String optimizer = 'sgd', double momentum = 0.9, double beta1 = 0.9, double beta2 = 0.999, double epsilon = 1e-8, double l2 = 0.0, String lrSchedule = 'constant', int stepSize = 10, double stepDecay = 0.5, double expDecay = 0.99, int epochsOverride = -1}) → void

Convenience training wrapper that calls the main fit implementation. (This class intentionally exposes a single training API.)

fitAsync(List<List<double>> X, List<List<double>> Y, {int? batchSize, bool verbose = false, String optimizer = 'sgd', double momentum = 0.9, double beta1 = 0.9, double beta2 = 0.999, double epsilon = 1e-8, double l2 = 0.0, String lrSchedule = 'constant', int stepSize = 10, double stepDecay = 0.5, double expDecay = 0.99}) → Future<void>

Asynchronous wrapper that runs fit in a Future (not in a separate isolate).

getParams() → Map<String, dynamic>

Return a simple params map (weights and biases) without other metadata.

markInitialized() → void

Public utility methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

predict(List<List<double>> X) → List<List<double>>

saveToFile(String path) → Future<void>

toJson() → String

JSON helpers

toMap() → Map<String, dynamic>

Serialize model parameters to a Map (JSON-ready).

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

fromJson(String s, {int? seed, int? epochs, double? lr}) → ANN

fromMap(Map<String, dynamic> m, {int? seed, int? epochs, double? lr}) → ANN

Reconstruct an ANN from a previously-serialized Map.

loadFromFile(String path, {int? seed, int? epochs, double? lr}) → Future<ANN>
