Hello NuPIC, Can you share your thoughts on the anomaly scores that HTM Engine is reporting on my self-generated datasets?
I'd like to experiment with different model parameters, but as far as I could see I can only offer the name, mininum value and maximum value. I'm very much interested in experimenting with the anomaly detection functionality, so I really hope someone can help me. In my set up I am using the skeleton-htm-engine-app from within a vagrant box. I am offering all of my data through the API of the HTM Engine. Since I am using the most basic implementation of the HTM Engine I doubt that making a public repo would help. If there are other factors that influence the output of HTM Engine, please let me know.
