Public Methods

public static BooleanMaskUpdate.Options axis (Integer axis)

Used to indicate the axis to mask from. axis + dim(mask) <= dim(tensor) and mask 's shape must match the first axis + dim(mask) dimensions of tensor 's shape.

Parameters
axis the axis to mask from. Uses 0 if null.

public static BooleanMaskUpdate.Options broadcast (Boolean broadcast)

Whether to try broadcasting update. True by default.

public static Operand <T> create ( Scope scope, Operand <T> tensor, Operand < TBool > mask, Operand <T> updates, Options... options)

Updates a tensor at the masked values, and returns the updated tensor. Does not mutate the input tensors. updates will be broadcasted by default

Numpy equivalent is `tensor[mask] = updates`.

In general, 0 < dim(mask) = K <= dim(tensor) , and mask 's shape must match the first K dimensions of tensor 's shape. We then have: booleanMask(tensor, mask)[i, j1,...,jd] = tensor[i1,...,iK,j1,...,jd] where (i1,...,iK) is the ith true entry of mask (row-major order).

The axis could be used with mask to indicate the axis to mask from (it's 0 by default). In that case, axis + dim(mask) <= dim(tensor) and mask 's shape must match the first axis + dim(mask) dimensions of tensor 's shape.

The shape of updates should be [n, t_1, t_2, ...] where n is the number of true values in mask and t_i is the i th dimension of tensor after axis and mask . updates will be broadcasted to this shape by default, which can be disabled using options .

Parameters
tensor The tensor to mask.
mask The mask to apply.
updates the new values
options carries optional attributes values
Returns
  • The masked tensor.
