Patent number: 12254398Abstract: To reduce the storage size of weight tensors and speed up loading of weight tensors from system memory, a compression technique can be employed to remove zero values from a weight tensor before storing the weight tensor in system memory. A sparsity threshold can be enforced to achieve a compression ratio target by forcing small weight values to zero during training. When the weight tensor is loaded from system memory, a direct memory access (DMA) engine with an in-line decompression unit can decompress the weight tensor on-the-fly. By performing the decompression in the DMA engine, expansion of the weight values back to the original weight tensor size can be carried out in parallel while other neural network computations are being performed by the processing unit.Type: GrantFiled: March 30, 2021Date of Patent: March 18, 2025Assignee: Amazon Technologies, Inc.Inventors: Kun Xu, Ron Diamant, Patricio Kaplan

Patent number: 12241174Abstract: A method used to repair a workpiece through a combination of laser and an electrochemical reaction is provided. A tool anode is arranged on the back side of the workpiece and is spaced therefrom. A laser beam is focused on an outer surface of the workpiece to realize localized repairing on the back side. The method realizes localized coating repairing on the back side of the workpiece through coordination between the thermal effect of the laser and the electrochemical deposition based on the characteristic of high thermal conductivity of the workpiece. The electrodeposition reaction does not occur in regions that do not need to be repaired. The operating process is simple, the cost of the plating solution is largely reduced, and the problem that the coating on the inner wall of the thin-walled workpiece is difficult to repair due to stripping is solved.Type: GrantFiled: May 31, 2022Date of Patent: March 4, 2025Assignee: JIANGSU UNIVERSITYInventors: Kun Xu, Zhihao Leng, Yangfan Tang, Sheng Guo, Zhaoyang Zhang, Hao Zhu, Yang Liu, Yucheng Wu, Wenhui Liang, Panzhou Li
