TimeGoal

is an option for various functions that specifies how long to spend doing a particular operation.

Details

TimeGoalt specifies that around t seconds of CPU time should be spent doing a particular operation.
TimeGoalQuantity[n,"unit"] specifies the time goal using a quantity. Possible forms for "unit" include "Seconds", "Minutes", "Hours".
Since different computer systems run at different speeds, the same setting for TimeGoal can lead to different results on different systems.

Train a classifier while specifying a total training time of 5 seconds:

Wolfram Language code: Classify[{1, 2, 3, 4} -> {"A", "A", "B", "B"}, TimeGoal -> 5] // AbsoluteTiming

Train a predictor while specifying a total training time of 3 seconds:

Wolfram Language code: Predict[{1, 2, 3, 4} -> {1, 2, 3, 4}, TimeGoal -> Quantity[3, "Seconds"]] // AbsoluteTiming
