training ↔ bool
Whether this module is in training mode. Layers that behave differently between training and inference (e.g. Dropout) read this flag in their call method. Defaults to training mode.

Methods

call(Tensor srcTokens, Tensor tgtTokens) → Tensor
Full forward: encode source, decode target against memory, return logits [St, targetVocabSize] or [B, St, V].
decode(Tensor tgtTokens, Tensor memory) → Tensor
Decoder-side forward given a precomputed memory (encoder output). Applies causal masking to the decoder self-attention.
encode(Tensor srcTokens) → Tensor
Encoder-only pass returning "memory" for the decoder.
eval() → void
Put this module (and any registered submodules) into evaluation mode.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
parameters() → List<Tensor>
Trainable tensors owned by this module (and its submodules).
override
submodules() → List<Module>
Submodules owned by this module. Subclasses that compose other modules should override this so train() / eval() propagate. Default: empty.
override
toString() → String
A string representation of this object.
inherited
train() → void
Put this module (and any registered submodules) into training mode.
inherited
zeroGrad() → void
Zero every parameter's gradient. Safe to call before each backward.

Operators

operator ==(Object other) → bool
The equality operator.
