merlin.models.tf.BroadcastToSequence

class merlin.models.tf.BroadcastToSequence(*args, **kwargs)

Bases: merlin.models.tf.core.base.Block

Broadcast context features to match the timesteps of sequence features.

This layer supports mask propagation. If the sequence features have a mask. The context features being broadcast will inherit the mask.

Parameters

• context_schema (Schema) – The schema representing contextual features to be broadcast

• sequence_schema (Schema) – The schema representing sequence features

__init__(context_schema: merlin.schema.schema.Schema, sequence_schema: merlin.schema.schema.Schema, **kwargs)
