Abstract: A computer-implemented method for generating unified soft labels is disclosed. In the computer-implemented method, a collection of samples is prepared. Then, a plurality of predictions generated by a plurality of individual trained models is obtained for each sample, in which each individual trained model has an individual class set to form at least partially a unified class set that includes a plurality of target classes. The unified soft labels are estimated for each sample over the target classes in the unified class set from the plurality of the predictions using a relation connecting a first output of each Individual trained model and a second output of the unified model. The unified soft labels are output to train a unified model having the unified class set.

Abstract: A method of disarming and reconstructing an encoded video stream to nullify malicious agents potentially embedded in the encoded video stream comprising decoding a received encoded video stream to obtain a decoded video stream, extracting, from the encoded video stream, encoding information calculated by an originating encoder to create the encoded video stream, adjusting the encoding information by replacing one or more quantization parameters defined in the encoding information with respective adjusted quantization parameter(s) calculated based on a random selection of a value from a range of quantization parameter values, encoding the decoded video stream using the adjusted encoding information to produce a modified encoded video stream and transmitting the modified encoded video stream.

Abstract: A method is directed to transmitting signals between neurons of a hardware-implemented, spiking neural network (or SNN). The network includes neuronal connections, each including a synaptic unit connecting a pre-synaptic neuron to a post-synaptic neuron. Spikes received from the pre-synaptic neuron of said each neuronal connection are first modulated, in frequency, based on a synaptic weight stored on said each synaptic unit, to generate post-synaptic spikes, such that a first number of spikes received from the pre-synaptic neuron are translated into a second number of post-synaptic spikes. At least some of the spikes received from the pre-synaptic neuron may, each, be translated into a train of two or more post-synaptic spikes. The post-synaptic spikes generated are subsequently transmitted to the post-synaptic neuron of said each neuronal connection. The method makes it possible to obtain a higher dynamic range in the synapse output.

Abstract: A computer implemented method is disclosed. The method includes executing, by a virtual machine that is executing on a host server, a stream of instructions, wherein an instruction from the stream of instructions is to be intercepted to a hypervisor. The method further includes, based on a determination that the virtual machine is a secure virtual machine, preventing the hypervisor from directly accessing any data of the secure virtual machine. The method further includes performing by a secure interface control of the host server, based on a determination that the instruction is not interpretable by the secure interface control itself, extracting one or more parameter data associated with the instruction from the secure virtual machine, and storing the parameter data into a buffer that is accessible by the hypervisor. The instruction is subsequently intercepted into the hypervisor.

Abstract: Mechanisms are provided for training a computer implemented model. The mechanisms perform multiple instances of training of the computer implemented model, wherein each instance of training of the computer implemented model comprises training the computer implemented model using a different training data set to generate a different instance of a trained computer implemented model. The mechanisms generate computer implemented model results after each instance of training by executing the corresponding instance of the trained computer implemented model. The mechanisms record differences in the instances of training of the computer implemented model in association with corresponding identifiers of the instances of trained computer implemented model and corresponding computer implemented model results. The mechanisms analyze the recorded differences and the corresponding computer implemented model results, and generate an output indicating a correlation between recorded differences and corresponding computer implemented model results.

Abstract: A single architected instruction to perform multiple functions is executed. The executing includes performing a first function of the multiple functions and a second function of the multiple functions. The first function includes moving a block of data from one location to another location, and the second function includes setting one portion of a storage key using one selected key and another portion of the storage key using another selected key. The storage key is associated with the block of data and controls access to the block of data. The first function and the second function are performed as part of the single architected instruction.

Abstract: Monitoring a process on an Internet of Things (IoT) device is performed by receiving, by the IoT device, a network data transfer from an external device; and receiving, by the IoT device, meta-information of the network data transfer. The meta-information can be generated, based on the network data transfer, by a network monitoring device. Additionally, the IoT device detects a file storing data of the network data transfer based on the meta- information. Further, the IoT device monitors a process relating to the detected file on the IoT device.
