#minecraft #neuralnetwork #backpropagation
I built an analog neural network in vanilla Minecraft without any mods or command blocks. The network uses Redstone wire power strengths to carry the signal through one hidden layer, including nonlinearities, and then do automatic backpropagation and even weight updates.
OUTLINE:
0:00 – Intro & Overview
1:50 – Redstone Components Explained
5:00 – Analog Multiplication in Redstone
7:00 – Gradient Descent for Square Root Computation
9:35 – Neural Network Demonstration
10:45 – Network Schema Explained
18:35 – The Network Learns a Datapoint
20:20 – Outro & Conclusion
I built this during a series of live streams and want to thank everyone who helped me and cheered for me in the chat!
