ContNonContractRV.L_op

ContNonContractRV.L_op(inputs, outputs, output_grads)

Construct a graph for the L-operator.

The L-operator computes a row vector times the Jacobian.

This method dispatches to Op.grad() by default. In one sense, this method provides the original outputs when they’re needed to compute the return value, whereas Op.grad doesn’t.

See Op.grad for a mathematical explanation of the inputs and outputs of this method.

Parameters:

• inputs (Sequence[Variable]) – The inputs of the Apply node using this Op.

• outputs (Sequence[Variable]) – The outputs of the Apply node using this Op

• output_grads (Sequence[Variable]) – The gradients with respect to each Variable in inputs.

Return type:

list[Variable]
