Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 19:
20. A semiconductor device comprising:
a circuitry for implementing an artificial neural network, the circuitry configured to:
receive a representation of an object to be classified as a target class in a set of target classes;
execute a first layer subnetwork of the artificial neural network to classify the object into either a first unknown class or into a first subset of target classes in the set of target classes, the first layer subnetwork comprising a first group of nodes on an output layer of the artificial neural network; and
if the object is classified into the first unknown class, execute a second layer subnetwork to classify the object into either a second unknown class or into a second subset of target classes in the set of target classes, the second layer subnetwork comprising a second group of nodes on the output layer of the artificial neural network;
wherein, if the object is classified into the first subset of target classes, the second layer subnetwork is not executed for classifying the object, wherein the first layer subnetwork and the second layer subnetwork share a same group of nodes on an input layer of the artificial neural network, and wherein nodes on the input layer are directly connected to nodes on the output layer.
