GatedRelativePositionBias

Description

GatedRelativePositionBias computes attention biases based on relative positions, with a gating mechanism that adapts their influence. It outputs a bias tensor added to the attention scores in Transformer models.

 

Input parameters

 

specified_outputs_name : array, this parameter lets you manually assign custom names to the output tensors of a node.

 Graphs in : cluster, ONNX model architecture.

query_layer (heterogeneous) – T : object, tensor with shape (batch_size, seq_len, num_heads x head_size) or (token_count, num_heads x head_size).
query_bias (heterogeneous) – T : object, 1-d tensor with shape (num_heads x head_size).
rel_pos (heterogeneous) – T : object, tensor with shape (1, num_head, seq_len, seq_len).
weight (heterogeneous) – T : object, gemm weight for the gated_ur_linear, shape (head_size, D), D is divisible by 2.
bias (heterogeneous) – T : object, bias for the gated_ur_linear, shape (D).
eco_a (heterogeneous) – T : object, tensor of shape (1, num_heads, 1, 1).
token_offset (optional, heterogeneous) – M : object, offset of each token with shape (batch_size, seq_len).

 Parameters : cluster,

num_heads : integer, number of attention heads.
Default value “0”.
 training? : boolean, whether the layer is in training mode (can store data for backward).
Default value “True”.
 lda coeff : float, defines the coefficient by which the loss derivative will be multiplied before being sent to the previous layer (since during the backward run we go backwards).
Default value “1”.

 name (optional) : string, name of the node.

Output parameters

 

 output (heterogeneous) – T : object, output tensor with shape (batch_size, num_heads, seq_len, seq_len).

Type Constraints

T in (tensor(float), tensor(float16)) : Constrain input and output types to float tensors.

M in (tensor(int32)) : Constrain token_offset to integer types.
