https://en.wikipedia.org/wiki/Test-and-setIn computer science, the test-and-set instruction is an instruction used to write (set) 1 to a memory location and return its old value as a single atomic (i.e., non-interruptible) operation. The caller can then "test" the result to see if the state was changed by the call. If multiple processes may

https://en.wikipedia.org/wiki/Training,_validation,_and_test_setsA training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier.
For classification tasks, a supervised learning algorithm looks at the training data set to determine, or learn, the optimal combinations of variables that will generate a good predictive model. The goal is to produce a trained (fitted) model that generalizes well to new, unknown dat…Wikipedia · Nội dung trong CC-BY-SA giấy phépTest-and-set — Wikipédia
https://fr.wikipedia.org/wiki/Test-and-setL'instruction test-and-set est une instruction atomique utilisée en informatique dans les systèmes multiprocesseurs ou multi-cœurs utilisant une mémoire partagée, elle sert à écrire une valeur prédéterminée dans un emplacement mémoire et retourner la valeur d'origine de cet emplacement. Elle possède le nombre de consensus numéro deux. Elle opère sur un seul mot …
