Bitwise

and

INDArray and(INDArray x, INDArray y)

SDVariable and(SDVariable x, SDVariable y)
SDVariable and(String name, SDVariable x, SDVariable y)

Bitwise AND operation. Supports broadcasting.

x (INT) - First input array
y (INT) - Second input array

bitRotl

INDArray bitRotl(INDArray x, INDArray shift)

SDVariable bitRotl(SDVariable x, SDVariable shift)
SDVariable bitRotl(String name, SDVariable x, SDVariable shift)

Roll integer bits to the left, i.e. var << 4 | var >> (32 - 4)

x (INT) - Input 1
shift (INT) - Number of bits to shift.

bitRotr

INDArray bitRotr(INDArray x, INDArray shift)

SDVariable bitRotr(SDVariable x, SDVariable shift)
SDVariable bitRotr(String name, SDVariable x, SDVariable shift)

Roll integer bits to the right, i.e. var >> 4 | var << (32 - 4)

x (INT) - Input 1
shift (INT) - Number of bits to shift.

bitShift

INDArray bitShift(INDArray x, INDArray shift)

SDVariable bitShift(SDVariable x, SDVariable shift)
SDVariable bitShift(String name, SDVariable x, SDVariable shift)

Shift integer bits to the left, i.e. var << 4

x (INT) - Input 1
shift (INT) - Number of bits to shift.

bitShiftRight

INDArray bitShiftRight(INDArray x, INDArray shift)

SDVariable bitShiftRight(SDVariable x, SDVariable shift)
SDVariable bitShiftRight(String name, SDVariable x, SDVariable shift)

Shift integer bits to the right, i.e. var >> 4

x (INT) - Input 1
shift (INT) - Number of bits to shift.

bitsHammingDistance

INDArray bitsHammingDistance(INDArray x, INDArray y)

SDVariable bitsHammingDistance(SDVariable x, SDVariable y)
SDVariable bitsHammingDistance(String name, SDVariable x, SDVariable y)

Bitwise Hamming distance reduction over all elements of both input arrays. For example, if x=01100000 and y=1010000 then the bitwise Hamming distance is 2 (due to differences at positions 0 and 1)

x (INT) - First input array.
y (INT) - Second input array.

leftShift

INDArray leftShift(INDArray x, INDArray y)

SDVariable leftShift(SDVariable x, SDVariable y)
SDVariable leftShift(String name, SDVariable x, SDVariable y)

Bitwise left shift operation. Supports broadcasting.

x (INT) - Input to be bit shifted
y (INT) - Amount to shift elements of x array

leftShiftCyclic

INDArray leftShiftCyclic(INDArray x, INDArray y)

SDVariable leftShiftCyclic(SDVariable x, SDVariable y)
SDVariable leftShiftCyclic(String name, SDVariable x, SDVariable y)

Bitwise left cyclical shift operation. Supports broadcasting.

Unlike #leftShift(INDArray, INDArray) the bits will "wrap around":

leftShiftCyclic(01110000, 2) -> 11000001

x (INT) - Input to be bit shifted
y (INT) - Amount to shift elements of x array

or

INDArray rightShiftCyclic(INDArray x, INDArray y)

SDVariable rightShiftCyclic(SDVariable x, SDVariable y)
SDVariable rightShiftCyclic(String name, SDVariable x, SDVariable y)

Bitwise right cyclical shift operation. Supports broadcasting.

Unlike rightShift(INDArray, INDArray) the bits will "wrap around":

rightShiftCyclic(00001110, 2) -> 10000011
