Abstract: A method for operating a cache memory having a set having multiple memory blocks configured for storing data blocks. In a write process of a data block into a memory block of the set, the data block is written into the memory block, a relevance rank value of the data block and a first access time rank value are determined. Rank data associated with the memory block are determined using a write rank mapping from the relevance rank value and the first access time rank value, and the determined rank data are stored. If no memory block of the set is free, a memory block that is to be overwritten is selected from the memory blocks of the set based on the rank data, which are associated with the memory blocks, and the data block to be stored is written into the selected memory block by using the write process.

Abstract: Systems and methods for constructing and managing a unique road sign knowledge graph across various countries and regions is disclosed. The system utilizes machine learning methods to assist humans when comparing a new sign template with a plurality of stored sign templates to reduce or eliminate redundancy in the road sign knowledge graph. Such a machine learning method and system is also used in providing visual attributes of road signs such as sign shapes, colors, symbols, and the like. If the machine learning determines that the input road sign template is not found in the road sign knowledge graph, the input sign template can be added to the road sign knowledge graph. The road sign knowledge graph can be maintained to add signs templates that are not already in the knowledge graph but are found in real-world by integrating human annotator's feedback during ground truth generation for machine learning.

Abstract: A method for the automated selection of data sets for a method for machine learning for detecting operating variables of a motor vehicle, in which methods, measuring signal sequences for particular operating variable ranges of the motor vehicle, are detected during the operation of the motor vehicle. In the method, the operating variable ranges are assigned memory areas, each including multiple slots, each of which is configured to store a data set containing a detected measuring signal sequence, and data sets already stored in the slots being overwritable with data sets newly detected instantaneously for the same memory area in each case. For each slot of a memory area in which a data set is stored, an estimated slot error value is formed and stored together with the measuring signal sequence. The data sets, whose estimated slot error value is comparatively low, are preferably overwritten.
