Patent number: 12112270Abstract: A generator for generating artificial data, and training for the same. Data corresponding to a first label is altered within a reference labeled data set. A discriminator is trained based on the reference labeled data set to create a selectively poisoned discriminator. A generator is trained based on the selectively poisoned discriminator to create a selectively poisoned generator. The selectively poisoned generator is tested for the first label and tested for the second label to determine whether the generator is sufficiently poisoned for the first label and sufficiently accurate for the second label. If it is not, the generator is retrained based on the data set including the further altered data. The generator includes a first ANN to input first information and output a set of artificial data that is classifiable using a first label and not classifiable using a second label of the set of labeled data.Type: GrantFiled: August 9, 2021Date of Patent: October 8, 2024Assignee: Advanced Micro Devices, Inc.Inventor: Nicholas Malaya

Patent number: 12105646Abstract: A system includes a memory implementing one or more virtual queues and a processor coupled to the memory. In response to issuing one or more requests for data, a processor maps one or more of the requests for data to a return queue structure. The processor then allocates one or more virtual queues to the return queue structure based on the mapped requests. In response to allocating the virtual queues to the return queue, the processor writes the data indicated in the mapped requests to the allotted virtual queues and enables the return queue for arbitration. When the return queue is enabled for arbitration, the processor reads out the data written to the allocated virtual queues, processes the read out data, and provides the processed data to a processing pipeline.Type: GrantFiled: December 1, 2021Date of Patent: October 1, 2024Assignee: Advanced Micro Devices, Inc.Inventor: Fataneh Ghodrat
