Hi everyone. I’m sorry about the delayed post, I’m still furiously catching up from Charlotte, as I’m sure are many of you.
Pleases read TOUISSANT, G et. al. 2011 “Computational models of symbolic rhythm similarity: Correlation with human Judgments” pages 380-402 & 418-424 only (pdf 1-23 & 39-45). (Feel free to skip experiments 2 and 3; I will summarize them in class).
In preparation for class, I would like everyone to ruminate on the relationships between different mathematical measures of rhythm similarity (symbolic) and human judgment of rhythms (heard) as similar. Specifically, what is the perceptual difference between swap and edit distances? Why do you believe edit distances performed better? Are there any rhythmic circumstances in which you might expect swap distances to better correlate to perception than edit distances? Do you have any thoughts on how to “change the edit distance so that it is impervious to counter examples” (421)? Might it be beneficial to reconstruct “distance” in a different way than the minimum number of required mutations? If so, how would we proceed?
My aim in these questions is to foster a discussion on: symbolic metrics, what different distances “mean,” experimental design, representation of results, and potential follow-up studies.
