Device for and computer implemented method of machine learning

A device for machine learning a model for mapping a dataset to a solution of a task depending on a first parameter, the device configured to:

• determine a second parameter for assigning the second parameter to the first parameter in a first iteration of learning;
• and
• determine a third parameter for determining a rate for changing the first parameter in at least one iteration of learning depending on the third parameter and depending on a measure for evaluating the solution to the task;
• wherein the determination of the second parameter or third parameter includes determining a solution of an initial value problem that depends on a derivative of the measure with respect to the first parameter;
• wherein the determination of the solution of the initial value problem includes determining a first part of the solution of the initial value problem depending on an initial value, determining a second part of the solution of the initial value problem depending on the first part, determining for the first part a partial derivative, determining for the second part a partial derivative, and determining the second parameter and/or the third parameter depending on at least one of the partial derivatives.

A non-transitory computer-readable medium on which is stored a computer program for machine learning a model for mapping a dataset to a solution of a task depending on a first parameter, the computer program, when executed by a computer, causing the computer to perform the following steps:

• determining a second parameter for assigning the second parameter to the first parameter in a first iteration of learning;
• and
• determining a third parameter for determining a rate for changing the first parameter in at least one iteration of learning depending on the third parameter and depending on a measure for evaluating the solution to the task;
• wherein the determining of the second parameter or third parameter includes determining a solution of an initial value problem that depends on a derivative of the measure with respect to the first parameter;
• wherein the determining of the solution of the initial value problem includes determining a first part of the solution of the initial value problem depending on an initial value, determining a second part of the solution of the initial value problem depending on the first part, determining for the first part a partial derivative, determining for the second part a partial derivative, and determining the second parameter and/or the third parameter depending on at least one of the partial derivatives.
