Abstract
A program compilation method and apparatus operate by: obtaining a first expression and a second expression of a program, where the first expression and the second expression generate a dependency relationship based on a first variable, and operation types of the first variable in the first expression and the second expression are different, and updating an operation type of the first variable; so that the first variable has no differential result or a result is zero after encountering a differential operation; separately processing the first expression and the second expression according to the updated operation type of the first variable, to obtain a corresponding derivative function expression; and; combining, based on a chain rule, derivative function expressions respectively corresponding to the first expression and the second expression, to obtain a compilation result of the program.
