Coding Challenge #128: Sketch-RNN Snowflakes with ml5.js

TL;DR

Creating snowflakes using a neural network from the Magenta Project with ml5 and SketchRNN models.

Transcript

(tooting train whistle) Hello, welcome to another holiday coding challenge! Again with the snowflakes! This is my second snowflake challenge, but in this time instead of creating an algorithm to draw a snowflake, I'm going to ask a neural network to draw a snowflake for me. Now, there's a lot of pieces to all of the work that's gone in to making th... Read More
