Maximum

Maximum  // Elementwise maximum operation

Description

Produces tensor of the same element type and shape as the two inputs, where the value at each coordinate of output is the maximum of the values at the corresponding input coordinates.

Mathematical Definition

\[\mathtt{output}_{i_0, \ldots, i_{n-1}} = \max(\mathtt{arg0}_{i_0, \ldots, i_{n-1}}, \mathtt{arg1}_{i_0, \ldots, i_{n-1}})\]

Backprop

\[\begin{split}\overline{\mathtt{arg0}} &\leftarrow \mathtt{Greater}(\mathtt{arg0}, \mathtt{arg1})\ \Delta \\ \overline{\mathtt{arg1}} &\leftarrow \mathtt{Greater}(\mathtt{arg1}, \mathtt{arg0})\ \Delta\end{split}\]

C++ Interface

class Maximum : public ngraph::op::util::BinaryElementwiseArithmetic

Elementwise maximum operation.

Public Functions

const NodeTypeInfo &get_type_info() const

Returns the NodeTypeInfo for the node’s class. During transition to type_info, returns a dummy type_info for Node if the class has not been updated yet.

Maximum()

Constructs a maximum operation.

Maximum(const Output<Node> &arg0, const Output<Node> &arg1, const AutoBroadcastSpec &auto_broadcast = AutoBroadcastSpec(AutoBroadcastType::NUMPY))

Constructs a maximum operation.

Parameters
  • arg0: Node that produces the first input tensor.

  • arg1: Node that produces the second input tensor.

  • auto_broadcast: Auto broadcast specification

size_t get_version() const

Return

Version of this node
