摘要： This disclosure relates to a computer-implemented method of controlling an algorithm, and a device for implementing said method, the method including developing the algorithm from a first state to a second state by a machine learning process; determining a second computational cost of executing the algorithm in its second state; determining if the second computational cost satisfies a trigger condition; and, if so, consolidating the algorithm from the second state to a third state, wherein a third computational cost of executing the algorithm in its third state is less than the second computational cost.

摘要： A computer implemented method for identifying a signal in a sequence of numerical values, the method including: converting the sequence of numerical values into a vector sequence by converting each value in the sequence to a normalized vector representation; generating a vector field comprising the vector sequence as a multi-dimensional data structure such that vectors in the vector sequence are plotted in sequence in the vector field; modeling a simulated flow of particles through the vector field such that a flow of each particle is influenced by vectors in the vector field; generating one or more static representations of the particles, each representation being generated at a particular point in time; and performing feature detection on each of the one or more static representations to identify features in the representation corresponding to the signal.

摘要： A computer implemented method of providing whole disk encryption for a virtualized computer system including providing a hypervisor having a data store and instantiating a disk image of the virtualized computer system as a first virtual machine (VM) having a virtual disk from which an operating system of the first VM can be booted; instantiating a second VM in the hypervisor including a software component executing therein, wherein the data store is a shared data store accessible by both the first and second VMs, the method further comprising: the software component accessing the first VM using privileged credentials to install a software agent in the first VM and to replicate the virtual disk of the first VM in the hypervisor data store as a duplicate disk, wherein the software agent is adapted to encrypt data written to, and decrypt data read from, the disk of the first VM at a runtime of the first VM; and the software component encrypting the duplicate disk and unmounting the copied disk and mounting the encrypted duplicate disk in the first VM so as to provide an encrypted disk for the first VM.

摘要： The present invention provides a method comprising: receiving a plurality of queries, each query specifying one or more quality-of-service (QoS) requirements for the transmission of a data flow in a network; determining a query prototype, the query prototype comprising at least one QoS component value based on the one or more QoS requirements; obtaining a plurality of items of route data, wherein each item of route data is associated with a corresponding route through the network and indicates a QoS component of the corresponding route; comparing the route data with the query prototype to identify routes which match the query prototype; and in the event that a selected number of routes match the query prototype, responding to a further query by transmitting a query response comprising a new QoS model based on the matching query prototype.

摘要： A method for detecting malware software in a computer system includes accessing a plurality of hostnames for a malware server from a computer system infected with malware and attempting to communicate with the malware server, each hostname including a plurality of symbols in each of a plurality of symbol positions; training an autoencoder based on each of the plurality of hostnames, wherein the autoencoder includes: a set of input units for each possible symbol and symbol position in a hostname; output units each for storing an output of the autoencoder; and a set of hidden units smaller in number than the set of input units and each interconnecting all input and all output units with weighted interconnections, such that the autoencoder is trainable to provide an approximated reconstruction of values of the input units at the output units; selecting a set of one or more symbol and symbol position tuples based on weights of interconnections in the trained autoencoder; and identifying infected computer systems based on their attempted communication to hostnames having symbols in symbol positions consistent with the tuples in the set.
