Nice write up!
I think you might see some interesting results using a non-parametric [one that doesn't require specifying the number of clusters apriori] clustering algorithm, like mean-shift. I've never seen an adaptation for discrete data like this, but it should be possible.
You could have the same tradeoff between note-distance and time-distance.
- edhu2017 9y agoCool, I'll definitely look into these types of algorithms. Do you have exposure to these? I'm still a 3rd year undergrad and my maths isn't strong enough yet to grok some of the crazier algorithms.
- loxias 9y agoI certainly do! Mean shift (https://spin.atomicobject.com/2015/05/26/mean-shift-clustering/ https://spin.atomicobject.com/2015/05/26/mean-shift-clusteri...) is commonly used in image/volume segmentation, when you have CPU to burn. I've done a decent amount of work on optimization of it. Actually I was curious enough about this novel use (and I happen to be interested in music myself, who isn't) I saw your post and thought about replicating it and emailing you results. I'd be more than happy to work with you on any non-commercial stuff. (An email address which works for me is on my HN profile, could you send me a note? Even if nothing else it doesn't make sense for all of us to spider/scrape the same datasets over and over...)
