Scala on the Move!
summary
Live demos show a Markov‑chain raga classifier that converts MLO pitch output into a note stream (notes normalized to a performer’s sa), builds Markov chains by sliding/counting/grouping with Scala collections, and reports ~10^10× higher log‑confidence for the correct raga. A web dashboard uses Scala.js + Akka‑HTTP, sends JSON over a 125ms timer WebSocket, streams OpenCV video as base64 PNGs, and adds datasets with a few lines. A home hub uses actor‑based remoting with cross‑compiled serialization, deployable jars to Raspberry Pis and voice/speech synthesis in the browser.
