Where3

public final class Where3

Selects elements from `x` or `y`, depending on `condition`.

The `x`, and `y` tensors must all have the same shape, and the output will also have that shape.

The `condition` tensor must be a scalar if `x` and `y` are scalars. If `x` and `y` are vectors or higher rank, then `condition` must be either a scalar, a vector with size matching the first dimension of `x`, or must have the same shape as `x`.

The `condition` tensor acts as a mask that chooses, based on the value at each element, whether the corresponding element / row in the output should be taken from `x` (if true) or `y` (if false).

If `condition` is a vector and `x` and `y` are higher rank matrices, then it chooses which row (outer dimension) to copy from `x` and `y`. If `condition` has the same shape as `x` and `y`, then it chooses which element to copy from `x` and `y`.

For example:

# 'condition' tensor is [[True,  False]
 #                        [False, True]]
 # 't' is [[1, 2],
 #         [3, 4]]
 # 'e' is [[5, 6],
 #         [7, 8]]
 select(condition, t, e)  # => [[1, 6], [7, 4]]
 
 
 # 'condition' tensor is [True, False]
 # 't' is [[1, 2],
 #         [3, 4]]
 # 'e' is [[5, 6],
 #         [7, 8]]
 select(condition, t, e) ==> [[1, 2],
                              [7, 8]]

Inherited Methods

Public Methods

public Output <T> asOutput ()

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.

public static Where3 <T> create ( Scope scope, Operand <Boolean> condition, Operand <T> x, Operand <T> y)

Factory method to create a class wrapping a new Where3 operation.

Parameters
scope current scope
x = A `Tensor` which may have the same shape as `condition`. If `condition` is rank 1, `x` may have higher rank, but its first dimension must match the size of `condition`.
y = A `Tensor` with the same type and shape as `x`.
Returns
  • a new instance of Where3

public Output <T> output ()

= A `Tensor` with the same type and shape as `x` and `y`.
