I don't follow that. The recidivism predictor was supervised. Conversely, AlphaZero is unsupervised and certainly not BS.

- hervature 7y agoAlphaZero is not unsupervised. It is a reinforcement learning algorithm, it knows exactly what the outcome of the game is.
- nokcha 7y agoThe terms "supervised machine learning" and "unsupervised machine learning", by their ordinary English meaning, make it sound like all machine learning is partitioned into one or the other. But a lot of the literature in machine learning considers reinforcement learning to be neither 'supervised learning' nor 'unsupervised learning'. See, e.g., section 1.1 of [1].
