T-norm - A T-norm, short for triangular norm, is a mathematical operation that combines two numbers between 0 and 1 while satisfying rules suited to a generalized “and.
T-norm fuzzy logics - T-norm fuzzy logics are formal systems of many-valued reasoning in which a triangular norm interprets a strong conjunction, or graded “and.
T scores - T scores, in standardized assessment, are scores expressed on a scale with a reference mean of 50 and reference standard deviation of 10.

Table - A table is a data structure organized into rows and columns.
Table 2 fallacy - The Table 2 fallacy is the mistake of interpreting every coefficient from one multivariable regression as though each estimated the intended causal effect...
Table lookup - Table lookup is the retrieval of a stored output using an input as a key or index.
Tabled logic programming - Tabled logic programming is a way of evaluating logic programs that stores answers to selected subgoals and reuses them when equivalent calls recur.
Tabu search - Tabu search is an optimization method that guides local search using memory of earlier moves or solution features.
Tabular data - Tabular data organize observations into rows and shared attributes into columns.
Tabular Q-learning - Tabular Q-learning is Q-learning implemented with an explicit table of action-value estimates, one entry for each represented state-action pair.
