How to calculate a meaningful distance between multidimensional tensors
You could try an earthmovers distance (https://en.m.wikipedia.org/wiki/Earth_mover%27s_distance) in 2d or 3d over the image? For example you could do this, but call sequentially (https://discuss....

Should I need to interpret the word "metric" in "performance metric" rigorously?
"Metric" should be understood as "a function of the trained model and of a dataset which returns a number".
For example, in reinforcement learning, one can use as an evaluation ...

What inherent quality of a function makes it treated as either loss or evaluation metric?
Common loss functions, like the cross-entropy or mean squared error, are chosen because, if you minimize them, you are actually maximizing the likelihood of the parameters given the observed data. In ...

Compare the efficiency of a trained ML model with a non-learning-based method for solving the same problem
The most generic answer to this question is:
the same metrics you use to evaluate the quality of your model during training or in test phase. (Plus the timing of inference if you're referring to ...

Does it make sense to use BLEU or ROUGE for any machine translation task?
Yes - and no. The important distinction is whether your data contains proper word boundaries and rigorous translation references.
BLEU and ROGUE both work by comparing a candidate (ie, model output) ...
