Title: Method and apparatus for neural architecture search
Inventor: Mohamed Saied Abdelkader Abdelfattah
IPC: G06N3/10
Filed: 2020-09-25
Abstract: Using a searching algorithm to design a neural network architecture by obtaining neural network models, selecting a subset of the models, using the searching algorithm on the subset, and repeating this for a number of iterations to identify an optimal neural network architecture by utilising a validation loss score. The score may be obtained: by calculating a gradient of a training loss function; by calculating an individual score for parameters of the neural network architecture and aggregating them into a global score; and/or by using single-shot network pruning, gradient signal preservation, synaptic flow, Jacobian covariance, L2 norm, gradient form, and/or Fisher information. Models may be ranked according to their score. Multiple scores may be calculated for each model, higher ranking occurring for majority scores indicating one model is better than another. The subset selection at a subsequent iteration of the model search may be informed by obtained model scores and may also include obtaining a performance metric for each model and comparing it with the model’s multiple scores to determine which score correlates with the metric. Performance metric and score may both be used to identify the optimal neural network.

IPC: H04L9/32
Filed: 2020-09-30
Abstract: A method for enabling a verifying party to verify an identity of a target party or device. The method comprises, in a set-up phase (702): inputting of each of a set of one or more challenges into a PUF module associated with the target party and comprising a physically unclonable function (PUF), to generate a respective one of a set of responses from each challenge (710); and causing to be stored, on a blockchain, a respective piece of response data for each of the set of one or more responses generated by the PUF module (720). The piece of response data for each response comprises the respective response or data derived therefrom. The pieces of response data are stored in one or more storage transactions recorded on the blockchain, thereby making at least one of the pieces of response data available (730) to the verifying party for verifying the identity of the target in a subsequent verification phase (704). Instead of storing the actual responses, the record could include an attestation of the response e.g. a signed hash, or a public/private key pair generated from the response.
