In general, I would be interested, how Eq (7) should be interpreted. Given m^{test,*} is the patch with the largest distance to its nearest neighbor in the memory bank and m^* is said nearest neighbor patch in the memory bank; then s^* is the distance between those patches (a scalar). What does it mean to weigh a scalar? The Softmax expression would result in a weighing vector, but how do you weigh a scalar with that?
The anomaly score is calculated using softmax of query distances (Eq (7) of the paper), but the code omits the process.
