Answer: No
The question asks whether using k=3 is the 'usual value choice' for k-fold cross-validation. The community discussion overwhelmingly supports that the standard or usual values for k in k-fold cross-validation are k=5 or k=10, not k=3. Multiple comments with high upvotes (e.g., 13 upvotes for 'usual choice is K=5 or 10') confirm this consensus. While k=3 can be used in specific scenarios (e.g., small datasets), it is not considered the typical or default choice. Therefore, the recommendation to use k=3 does not satisfy the requirement of using the 'usual value choice'.
