A Deep Learning Technique, Decoding The Rubik's Cube - ELE Times

A deep-learning technique that can learn a so-called "fitness function" from a set of sample solutions to a problem has been devised. This technique was initially trained to solve the Rubik's cube, the popular 3-D combination puzzle invented by Hungarian sculptor Ernő Rubik. The aim was to use machine learning to learn to solve the Rubik's cube. Rubik's cube is a very complex puzzle, but any of the vast numbers of combinations is at most 20 steps from a solution. So the approach here is to try and solve the problem by learning to do each of those steps individually. The technique is based on two main approaches: stepwise learning and the use of a deep neural network.
