org.tensorflow.op.math

Class ArgMax<V extends Number>

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.math.ArgMax<V>

Type Parameters:

V - data type for output() output

All Implemented Interfaces:

Op, Operand<V>

@Operator(group="math")
public final class ArgMax<V extends Number>
extends PrimitiveOp
implements Operand<V>

Returns the index with the largest value across dimensions of a tensor.

Note that in case of ties the identity of the return value is not guaranteed.

Usage:

   import tensorflow as tf
   a = [1, 10, 26.9, 2.8, 166.32, 62.3]
   b = tf.math.argmax(input = a)
   c = tf.keras.backend.eval(b)
   # c = 4
   # here a[4] = 166.32 which is the largest element of a across axis 0

Factory method to create a class wrapping a new ArgMax operation.

Parameters:

scope - current scope

input -

dimension - int32 or int64, must be in the range `[-rank(input), rank(input))`. Describes which dimension of the input Tensor to reduce across. For vectors, use dimension = 0.

outputType -

Returns:

a new instance of ArgMax

create

public static <T,U extends Number> ArgMax<Long> create(Scope scope,
                                                       Operand<T> input,
                                                       Operand<U> dimension)

Factory method to create a class wrapping a new ArgMax operation using default output types.

Parameters:

scope - current scope

input -

dimension - int32 or int64, must be in the range `[-rank(input), rank(input))`. Describes which dimension of the input Tensor to reduce across. For vectors, use dimension = 0.

Returns:

a new instance of ArgMax

output

public Output<V> output()

asOutput

public Output<V> asOutput()

Description copied from interface: Operand

Returns the symbolic handle of a tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

Specified by:

asOutput in interface Operand<V extends Number>
