Types of loss reduction.
Contains the following values:
NONE: Un-reduced weighted losses with the same shape as input.SUM: Scalar sum of weighted losses.MEAN: Scalar SUM divided by sum of weights. DEPRECATED.SUM_OVER_BATCH_SIZE: Scalar SUM divided by number of elements in losses.SUM_OVER_NONZERO_WEIGHTS: Scalar SUM divided by number of non-zero
weights. DEPRECATED.SUM_BY_NONZERO_WEIGHTS: Same as SUM_OVER_NONZERO_WEIGHTS. DEPRECATED.
