tf.unsorted_segment_min( data, segment_ids, num_segments, name=None )
Defined in tensorflow/python/ops/gen_math_ops.py
.
Computes the minimum along segments of a tensor.
Read the section on segmentation for an explanation of segments.
This operator is similar to the unsorted segment sum operator found (here). Instead of computing the sum over segments, it computes the minimum such that:
\(output_i = \min_j data_j\) where min is over 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<T>::max()
.
