T
- data type for output()
output@Operator(group="math") public final class UnsortedSegmentMin<T extends Number> extends PrimitiveOp implements Operand<T>
Read [the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation) for an explanation of segments.
This operator is similar to the unsorted segment sum operator found [(here)](../../../api_docs/python/math_ops.md#UnsortedSegmentSum). Instead of computing the sum over segments, it computes the minimum such that:
\\(output_i = \min_{j...} data_[j...]\\) where min is over tuples `j...` such that `segment_ids[j...] == i`.
If the minimum is empty for a given segment ID `i`, it outputs the largest
possible value for the specific numeric type,
`output[i] = numeric_limits
For example:
If the given segment ID `i` is negative, then the corresponding value is
dropped, and will not be included in the result.
c = tf.constant([[1,2,3,4], [5,6,7,8], [4,3,2,1]])
tf.unsorted_segment_min(c, tf.constant([0, 1, 0]), num_segments=2)
# ==> [[ 1, 2, 2, 1],
# [5, 6, 7, 8]]

output()
Has same shape as data, except for the first `segment_ids.rank`
dimensions, which are replaced with a single dimension which has size
`num_segments`.
