At issue was an algorithm called Q* (pronounced “Q-star”), which has allegedly been shown to solve certain grade-school-level math problems that it hasn’t seen before.

A* is also fairly old- it’s a heuristic-based path finding algorithm. In typical engineering fashion, they may have found an intersection of the 2 and named it Q*. This is total speculation, but if ...

Q-learning is a model-free, value-based, off-policy algorithm for reinforcement learning that will find the best series of actions based on the current state. The “Q” stands for quality.

Reinforcement learning (RL) is a branch of machine learning that addresses problems where there is no explicit training data. Q-learning is an algorithm that can be used to solve some types of RL ...
