Definitions
- the invention relates to a method and a device for providing a database for evaluating the robustness of at least one AI-based information processing system.
- Machine learning for example based on neural networks, has great potential for use in modern driver assistance systems and automated vehicles.
- Functions based on deep neural networks process sensor data (e.g. from cameras, radar or lidar sensors) in order to derive relevant information from it.
- sensor data e.g. from cameras, radar or lidar sensors
- This information includes, for example, a type and a position of objects in the area surrounding the motor vehicle, a behavior of the objects, or a roadway geometry or topology.
- An essential feature in the development of AI-based information processing systems lies in the purely data-driven parameter fitting without expert intervention.
- a deviation of an output (for a given parameterization) of the neural network from a ground truth is determined (the so-called loess).
- the loss function used here is selected in such a way that the parameters of the neural network depend on it in a differentiable manner.
- the parameters of the neural network are adjusted in each training step depending on the derivation of the deviation (determined on several examples). These training steps are repeated very often until the loess no longer decreases.
- an AI-based information processing system in particular a neural network
- the parameters of an AI-based information processing system are determined without an expert assessment or semantically motivated modeling. This can have significant consequences for the properties of the AI-based information processing system, in particular the neural network.
- deep neural networks are largely non-transparent for humans and their calculations are difficult to interpret. This poses a massive limitation to systematic testing or formal verification.
- neural networks in particular are susceptible to harmful interference, so-called adversarial perturbations: small manipulations of the input data that are hardly perceptible to humans or do not change a semantic content can lead to completely different output data.
- disruptive influences can be both intentional changes to the data ("neural hacking") and random image changes (sensor noise, weather influences, certain colors or contrasts).
- neural networks trained in simulation or on otherwise synthetic data have an astonishingly poor performance on real sensor data.
- Executing neural networks in a different data domain training in summer, execution in winter, etc.
- One of the consequences of this is that the possibility of developing and releasing neural networks in simulation (elimination of expensive labeling and complex real tests), which sounds very attractive from the cost point of view, does not seem realistic.
- the second point in particular is of great importance for possible limitations of potent neural networks in the area of functional safety.
- it is essential to measure an assessment of the robustness of the network design against minor changes (augmentations) of the input data. Since such changes can be manifold (sensor noise, weather influences, image manipulations, semantically meaningless content changes, e.g. the wall color of background buildings), there is no clear and accepted measure of robustness. Rather, many robustness values against disturbances (i.e. augmentations) of various types and intensities must be measured.
- the robustness of neural networks is not an absolute value, but rather dependent on current input data.
- the invention is therefore based on the object of providing a method and a device for providing a database for the robustness assessment of at least one AI-based information processing system.
- a method for providing a database for the robustness assessment of at least one AI-based information processing system having a function for automated driving of a motor vehicle and/or for driver assistance of the motor vehicle and/or for environment detection and/or or environmental perception or for another application, with at least one Kl-based information processing system, at least one data set, at least one data augmentation definition and at least one difference measure definition being received as input parameters, with a multidimensional data structure being generated based on the input parameters, with the dimensions and value ranges of Dimensions of the multidimensional data structure are defined by the received input parameters, and each data point of the multidimensional data structure has a middle ls of the at least one defined difference measure, which is determined by forming the at least one defined difference measure between output data, which is formed by the at least one KI-based information processing system for data of the at least one data set and for the same by means of the at least one defined data augmentation augmented data were generated, and wherein the generated multidimensional data structure is provided, so
- a device for providing a database for the robustness assessment of at least one AI-based information processing system comprising a data processing device, the data processing device being set up for this purpose is to receive at least one Kl-based information processing system, at least one data set, at least one data augmentation definition and at least one differential dimension definition as input parameters, and to generate a multidimensional data structure based on the input parameters, with the dimensions and value ranges of the dimensions of the multidimensional data structure being determined by the received input parameters are defined, and wherein each data point of the multidimensional data structure has a difference determined by means of the at least one defined difference measure zwert, which is determined by forming the at least one defined difference measure between output data that was generated by inference from the AI-based information processing system for data in the at least one data set and for the same data augmented by means

Therefore, at least one AI-based information processing system, at least one data set, at least one data augmentation definition and at least one difference measure definition are received for generating the multidimensional data structure. For each combination of these dimensions, i.e. for each possible characteristic within the dimensions, a difference value is calculated using the respective difference measure and stored for the associated data point.
- the difference value defined via the respective difference measure definition is determined from the output data that is generated by the at least one CI-based information processing system for (non-augmented) data of the data set and for augmented data.
- the augmented data is defined using the for the data point via the data augmentation definition data augmentation generated.
- there is a combination of at least the dimensions Kl-based information processing system, data set, data augmentation definition and difference measure definition i.e. for each data point there is a Kl-based information processing system, a data set, a data augmentation (or a data augmentation method ) and a difference measure is defined.
- data of the data set are augmented for the data point by means of data augmentation (e.g. disturbed) and a difference value between the non-augmented data and the augmented data of the data set is determined using the difference measure by applying the AI-based information processing system to the data.
- the determined difference value is stored in the data point. This procedure is carried out for all data points until a difference value has been determined and stored for each of the data points within the multidimensional data structure.
- the difference values can later be retrieved from the data structure at any time in a targeted manner, i.e.
- One advantage of the method and the device is that the robustness of a AI-based information processing system can be measured and evaluated even without the AI-based information processing system, i.e. without a model description (structure,

- the provision of the multidimensional data structure 20 makes it possible in particular to be able to assess the robustness 25 of a AI-based information processing system 10 even without the data 11a and without the AI-based information processing system 10 itself. This is particularly useful for sensitive data.
- Histogram scalar value Heatmap cake graphic Desired filter criterion Desired axis or dimension selection Desired aggregation method Desired visualization method Process step -102 Process steps -202 Process steps Metric generator
