+**Short description**: *NotEqual* performs element-wise comparison operation with two given tensors applying
+multi-directional broadcast rules specified in the `auto_broadcast` attribute.
+
+**Detailed description**
+Before performing comparison operation, input tensors *a* and *b* are broadcasted if their shapes are different.
+Broadcasting is performed according to `auto_broadcast` value.

+After broadcasting, *NotEqual* does the following with the input tensors *a* and *b*:
