Title: Facial behaviour analysis
Inventor: Stefanos Zafeiriou
IPC: G06N3/02
Filed: 2019-06-28
Abstract: This invention relates to methods for analysing facial behaviour in facial images using neural networks (NN). A first aspect covers a method of training a NN 212, the method comprising: inputting to the NN a plurality of facial images, the images comprising: one or more images from a first dataset 202-1 wherein each image comprises a known emotion label 204 (e.g. happy, sad); and one or more images from a second dataset 201-2 wherein each image comprises a known action unit activation 206 (e.g. wrinkled nose, raised eyebrow). The method further comprises: generating for each of the images using the NN, a predicted emotion label 214 and predicted action unit activation 216; then updating parameters of the NN in dependence on a comparison of the predicted and known emotion labels, and the predicted and known action unit activations. The comparison could be performed using a multi-task function 222-226 for calculating losses, e.g. cross entropy loss. Further images 202-3 having known arousal or valence values 208 could also be used. A second aspect covers using the trained NN to classify facial images.

Title: Processing service requests and processing DNS queries in telephony networks
Inventor: SALEM AMIN AL-DAMLUJI
IPC: H04M3/436
Filed: 2020-03-04
Abstract: A service request for a telephony service (e.g. a telephone call, or SMS/MMS messaging) provided by a network 130 is received by a DNS client 160. The client transmits a DNS query to a private DNS server 170, the query comprising data derived from the service request, e.g. data derived from a calling and/or called telephone number. The DNS query may be an ENUM (E.164 number to URI mapping) based query. A DNS response, e.g. ENUM response, is received indicative of a handling action to be performed in relation to the service request. A telephony service handling outcome, e.g. reject or accept the service request, is determined based at least in part on the handling action indicated by the DNS response, and the service request is processed accordingly. As a result, unwanted calls can be rejected. The DNS server may apply one or more rules to information within the query and respond with a DNS response code (RCODE) indicating the handling action. Multiple DNS/ENUM servers may be queried and the service handling outcome based on the multiple responses. The DNS query may use an extension mechanism for DNS (EDNS) to indicate additional information associated with the service request.
