BiasDropout - 1 (com.microsoft)#
name: BiasDropout (GitHub)
This version of the operator has been available since version 1 of domain com.microsoft.
output, dropout_mask = Dropout(data + bias, ratio) + residual, Intended to specialize the dropout pattern commonly found in transformer models.
seed: (Optional) Seed to the random generator, if not specified we will auto generate one. Default value is
Between 2 and 5 inputs.
data (heterogeneous) - T: The input data as Tensor.
bias (heterogeneous) - T: The bias input, a vector with the same shape as last dim of data OR same shape with data
residual (optional, heterogeneous) - T: The residual input, must have the same shape as data
ratio (optional, heterogeneous) - T1: The ratio of random dropout, with value in [0, 1). If this input was not set, or if it was set to 0, the output would be a simple copy of the input. If it’s non-zero, output will be a random dropout of the scaled input, which is typically the case during training. It is an optional value, if not specified it will default to 0.5.
training_mode (optional, heterogeneous) - T2: If set to true then it indicates dropout is being used for training. It is an optional value hence unless specified explicitly, it is false. If it is false, ratio is ignored and the operation mimics inference mode where nothing will be dropped from the input data and if mask is requested as output it will contain all ones.
Between 1 and 2 outputs.
output (heterogeneous) - T: The output.
mask (optional, heterogeneous) - T2: The output mask of dropout.
