Title: Setting operating system parameters based on workload types
Inventor: Karthikeyan Palavedu Saravanan
IPC: G06F9/50
Filed: 2017-11-30
Abstract: A computer-implemented method of setting operating system parameters (e.g. CPU frequency) that includes: identifying at least one software workload type (e.g. scene in a game vs a pop-up menu in the game) and generating a workload-specific policy. The workload type may be found using recorded metrics. The metrics may be taken over a certain timeframe and may concern, for example, fps (frames per sec), GPU utilisation and CPU utilisation (see fig 4A). The metrics may be filtered (see fig 4B). Subsequently the three metrics may be clustered (see fig 4C) using a DBSCAN or k-means method. In fig 4C, different shades of points illustrate three distinct scene clusters/workload types. In this way, three workload types may be identified (see graph 408, fig 4D). Based on the identified workload type (204A, B or C), a work-load specific policy (“per-scene policy”, 210A, B or C) is selected. A second invention concerns a method of modifying the per-scene policy using a generic policy (see steps 208 and 212 and figs 5-8). The step of modifying the generic policy may be based on an imitation learning technique.

Title: Anti-spoofing
Inventor: Symeon Nikitidis
IPC: G06N3/08
Filed: 2018-12-04
Abstract: A method of configuring an anti-spoofing system 150 to detect if a spoofing attack has been attempted. An image processing component (308) of the anti-spoofing system is trained to process 2D verification images (600) according to a set of image processing parameters in order to extract depth information from the 2D images. The configured anti-spoofing system uses an output from the processing of a 2D image to determine whether an entity captured in that image corresponds to an actual human or a spoofing entity. The image processing parameters are learned during training from a set of 3D training images of both actual humans and spoofing entities, each 3D image comprising 2D image data and corresponding depth data. The training comprises processing the 2D image data of each 3D training image according to the image processing parameters, so as to compute an image processing output for comparison with the corresponding depth data of that 3D image; and adapting the image processing parameters in order to match the image processing outputs to the corresponding depth data, thereby training the image processing component to extract depth information from 2D verification images. An independent claim is also included for determining spoofing attacks.

Filed: 2020-02-17
Abstract: Method of training a neural network classifier, comprising: extracting from the neural network 204 a plurality of subclass centre vectors 210; generating an embedding vector 206 from an input image 202; determining a similarity score 212 between the embedding vector and each of the subclass centre vectors; updating neural network parameters 214 in dependence each of the similarity scores using an objective function; and extracting and updating each subclass centre vector from the neural network. Subclass centre vectors may be extracted from the neural network’s last fully connected layer. The objective function may comprise a multi-centre loss term such as a margin-based Softmax loss function, that determines, for the embedding vector, a closest subclass centre vector for each class using the similarity scores. The embedding vector and subclass centre vectors may be normalised, and the similarity score an angle therebetween. The objective function may comprise an intra-class compactness term that uses the intra-class normalized angle similarity score between sub-class a dominant vector and the other sub-classes. Non-dominant subclasses may be discarded after a number of training cycles have been run. The method may be used to train a neural network on face images that contain noise (wrong labels).
