4results about How to "Reduce incompleteness" patented technology

The invention discloses an agricultural multi-source knowledge migration method based on a graph model, and belongs to the technical field of agricultural information, and the method comprises the steps: carrying out the reduction, feature selection and feature fusion of agricultural literature data; the data processing efficiency and accuracy are improved by utilizing agricultural data reduction based on self-organizing mapping and feature selection and fusion based on spatial mapping; constructing a knowledge migration network based on a graph model, and performing knowledge semantic extraction and knowledge migration relationship mining; agricultural multi-carrier meta-knowledge acquisition and information feedback are adjusted, and meta-knowledge acquisition and network weight adjustment are optimized. According to the method, large-scale and heterogeneous agricultural data can be effectively processed, effective migration of knowledge is realized, the performance of agricultural learning tasks is greatly improved, and the method is of great significance to improvement of agricultural production efficiency.

The utility model relates to the technical field of molds, in particular to an integrated steel casting mold. The integrated steel casting mold comprises a bottom plate, the top of the bottom plate is provided with a connecting assembly, the connecting assembly comprises a containing plate and supporting frames, the containing plate is arranged above the bottom plate, the two sides of the bottom of the containing plate are each provided with a supporting plate, and the bottom of the containing plate is slidably connected with the top of the bottom plate; the two supporting frames are symmetrically distributed on the two sides of the containing bottom. According to the integrated steel casting mold, due to the arrangement of the connecting assembly, the top mold can move in a reciprocating mode in the pouring process, vibration generated in the pouring process can vibrate molten steel poured in the upper bottom frame and the top mold, driving force is applied to the molten steel so that flowing and filling of the molten steel can be more sufficient and even, and the casting quality is improved. Therefore, the phenomenon that in the pouring process, bubbles at the corners in the top mold are not completely eliminated, and consequently pouring products are incomplete can be reduced.

The application belongs to the technical field of mobile power sources, and particularly relates to a dustproof and waterproof system and method of a mobile power source with a magnetic interface hidden structure, which comprises a shell, an energy storage assembly arranged in the shell, an output charging connector connected with the energy storage assembly, a charging assembly connected with the energy storage assembly, a magnet, and a protection assembly arranged outside the shell. When the charging assembly is closed in a magnetic mode, the charging assembly is used to separate the output charging connector from the external environment. When the charging assembly is opened, the output charging connector is exposed to the external environment. The protection assembly is used to separate the magnet from the external environment. The charging assembly comprises an output wire used to connect the energy storage assembly and the output charging connector, and a wire box used to accommodate the output charging connector. The output wire and the wire box are inserted into each other in a magnetic mode. The two output wires and the corresponding output charging connectors are inserted into the same wire box, and the holes on the two sides of the wire box are sealed by sealing members, so that dust and water are blocked outside the shell.

The present disclosure provides a log collection method and device for GPU virtualization driver, and a medium, relating to the technical field of GPU virtualization. The method comprises: constructing an isolated and efficient log transmission channel by allocating an independent shared memory area for each guest virtual machine on the host side and completing address mapping; at the same time, starting an independent log reading thread and reading the log in the shared memory on demand based on a configurable log collection mode, while recording the log generated on the host side, realizing the synchronous collection of double-end logs, keeping the system at low overhead during normal operation, and obtaining complete context information when an exception occurs; by comprehensively analyzing the first driving operation log from the shared memory and the second driving operation log on the host side, the running behavior link across the host and the virtual machine can be associated and restored, the accuracy and efficiency of abnormal diagnosis are improved, and the resource occupation and maintenance complexity caused by additional components are reduced.
