Deci and Ryan's Self-Determination Theory treats autonomy, competence, and relatedness as three equally fundamental, innate psychological needs — none is placed at the theoretical centre with the others positioned beside it.

Overfitting is properly defined by a gap between training and test/validation performance — the model fits training data (including its noise) too closely relative to how well it performs on new data — not by the training score being literally perfect. A model can be overfit while scoring well below 100% on training data, and conversely a model can achieve near-perfect training fit without being meaningfully overfit ('benign overfitting'). The memorization framing is accurate; the 'scores perfectly' framing is an oversimplification flagged in the ML education literature as a documented student misconception.#
