Just to be clear about terminology:
Top Motif -> Lowest Distance to Nearest Neighbor -> Smallest Value in MatrixProfile
Top Outlier -> Highest Distance to Nearest Neighbor -> Largest Value in MatrixProfile

The red event contains a low distance at the start and a high distance at the end.
Maybe the window-size is too long.

Furthermore vanilla STOMP ignores the magnitude of the input data, because each window gets normalized to 0-mean and unit-std.
Therefore the physical magnitude of the data is lost. Only the shape matters for motif-detection.

You can transform the z-normalized euclidean distance to pearson-correlation.
Pearson-R is easier for interpretation.
