Detailed Documentation

Gaussian Error Linear Unit f(x) = 0.5 * x * (1 + erf( x / sqrt(2) ) for “approximation” = “erf” f(x) = 0.5 * x * (1 + tanh([sqrt(2 / pi)] * [x + 0.044715^3]) for “approximation” = “tanh”.

Construction

Gelu(
    const Output<Node>& data,
    GeluApproximationMode mode = GeluApproximationMode::ERF
    )

Constructs a Gelu operation.

Parameters:

data

Input tensor

mode

Approximation mode

Methods

virtual void validate_and_infer_types()

Verifies that attributes and inputs are consistent and computes output shapes and element types. Must be implemented by concrete child classes so that it can be run any number of times.

Throws if the node is invalid.

virtual bool evaluate(
    const HostTensorVector& output_values,
    const HostTensorVector& input_values
    ) const

Evaluates the op on input_values putting results in output_values.

Parameters:

output_values

Tensors for the outputs to compute. One for each result

input_values

Tensors for the inputs. One for each inputs.

Returns:

true if successful

virtual bool has_evaluate() const

Allows to get information about availability of evaluate method for the current operation.
