Why is RMSE generally the preferred performance measure for regression tasks?   A. Because it gives an idea of the average percentage deviation of the predictions from the actual values.   B. Because it gives an idea of the average absolute deviation of the predictions from the actual values.   C. Because it gives an idea of how much error the system typically makes in its predictions, with a higher weight given to large errors.   D. Because it gives an idea of the average deviation of the predictions from the actual values.

Temporal difference learning

Temporal difference learning (TD learning) is a concept in machine learning that attributes to a class of model-free reinforcement learning methods. The technique predicts a reward or quantity depending on the future values of the value function.
