Abstract: A method for generating program code which, when executed on a hardware platform, creates a neural network having a given architecture. In the method: for at least one layer and/or group of neurons, a non-linear activation function of the neurons in that layer and/or group is ascertained from the given architecture; possible values that can be assumed by the activation function are precalculated and stored in a lookup table; program code is generated which, for all neurons in the layer and/or group respectively: aggregates the inputs of the respective neuron to form an argument of the activation function in accordance with the given architecture, ascertains an index from this argument, under which the associated value of the activation function is stored in the lookup table for the respective layer or group, and ascertains the output of the neuron by retrieving the value from the lookup table with this index.

Abstract: A method for providing a neural network on a data processing device. The method includes: ascertaining, from a set of implementation variants of the neural network, a subset with a plurality of implementation variants of the neural network, wherein each implementation variant of the subset cannot be improved with respect to any of main memory requirement, non-volatile memory requirement, and execution time, when executed on the data processing device, without impairing at least one of the other two, and the subset for each of main memory requirement, non-volatile memory requirement and execution time, when executed on the data processing device, contains at least one particular implementation variant that is optimal in this respect from the set of implementation variants; selecting one of the ascertained implementation variants according to a user input that specifies a selection from the subset; and storing the selected implementation variant in the data processing device.

Abstract: A method for creating a model of a technical system as a function of measured sensor data of the technical system. The method includes the following steps: initializing a symbolic regression problem. A list of mathematical functions is established, including at least one linear and/or non-linear function and/or at least a one-dimensional parameterizable characteristic curve. The at least one-dimensional characteristic curve is implemented by a Smoothed Grid Regression (SGR) model. Solving the symbolic regression problem with the aid of a genetic algorithm.

Abstract: A device and a computer-implemented method for classifying data, in particular for a Controller Area Network or an automotive Ethernet network. A plurality of messages is received from a communications network. A message that has a predefined message type is selected for an input variable for an input model of a plurality of input models of an artificial neural network associated with the predefined message type. The input variable is determined as a function of the message, and in an output area of the artificial neural network a prediction is output that is usable for classifying the message as a function of the input variable, or a reconstruction of an input variable is output that is usable for classifying the message as a function of this input variable.
