TLDR: Article describes a method to define “registers”, “heads” and non-linear “compute” functions which are compiled and distilled into a standard Transformer model. This is used to develop a simple and deterministic RPN interpreter. Code accompanying this project can be found here . AI disclaimer: code ≈ 50%, non-agentic. Article writing = 0%. A few weeks ago…
Note: code accompanying this project can be found here . This weekend, as an afterthought, I guess due to some background threads that had been accumulating in my head for a while, I decided to finally take a quick & dirty shot at one of those things that’s fascinated me, but not quite enough to actually get around to trying it until quite some time has passed: the Decision Transformer 1…
Some info on projects I have done by myself or with other people.
To hear and touch I am a researcher and developer. I am interested in mechanisms , how to control them, how we control them, the signals they generate, and how we perceive these through haptic and audio channels.
Project page The idea behind this project was to see if I could use a neural network, specifically, an autoencoder, to embed the parameter space of a physical modeling audio synth. There are some good/bad issues but in general it worked. The result is a small neural network (2- or 3-unit wide input layer, 100 hidden, 200- wide output layer) that transforms a set of parameters into a sound that is…
I’ve always been driven by the challenge of using the computer as a medium for human interaction and expression. My career began with the tangible, real-time signals of touch and sound, learning to control robotic and haptic systems for audio interaction. For the last decade, I’ve applied that same drive to machine learning, exploring how computers can perceive the world through…
Here are some articles that I find inspiring. I hope to do blog posts soon on what they are and why I find them interesting. J. P. Fiene and K. J. Kuchenbecker, “Shaping event-based haptic transients via an improved understanding of real contact dynamics,” in Proc. World Haptics , pp. 170–175, IEEE, 2007. V. Kumar, E. Todorov, and S. Levine, “Optimal control with learned…
