Public Methods

public static BooleanMask.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 BooleanMask.Options axis (int 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.

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

Apply boolean mask to tensor. Returns the flat array of each element corresponding to a true in the mask.

Numpy equivalent is tensor[mask] .

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.

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