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.all
@classmethod all()

MEAN = 'weighted_mean'
NONE = 'none'
SUM = 'weighted_sum'
SUM_BY_NONZERO_WEIGHTS = 'weighted_sum_by_nonzero_weights'
SUM_OVER_BATCH_SIZE = 'weighted_sum_over_batch_size'
SUM_OVER_NONZERO_WEIGHTS = 'weighted_sum_by_nonzero_weights'
