How can I interpret ate the DTW graph.
I understood the algorithm behind DTW, but I struggle to interpret ate the graph.
When I compute the DTW for a signal that is the same signal but shifted in time, my result will be a diagonal, straight line from top right to bottom left. When the signal does not match exactly, I would see some deviation from the ideal diagonal line.
But how to be exact about the outcome?
I try to explain my issue from a different perspective
When I calculate the standard Euclidean distance I can say as bigger the value as bigger the error, but what about the values calculated with DTW?
