The application discloses a user cold start recommendation system and method based on similarity matching, constructs a knowledge graph database according to users, products and the interaction relationship between the users and the products, and carries out standardization processing. The processed data is extracted to score information and mapped to a user like-dislike type space, so that the like-dislike product type of each user is determined, and a similarity matching algorithm is designed to find the old user with the highest similarity to the new user. The old user product type score vector and the new user product type vector score are processed by an association function and used as the recommendation basis of the system, the reasonable expansion of the new user data is completed, and the cold start problem of the recommendation system is effectively alleviated. The application solves the user cold start problem caused by the introduction of a new user into an industrial recommendation system. The application can be used for the scene of effectively recommending the product types that meet the preferences of new users in the industrial recommendation system.

The utility model provides a LAN data centralized monitoring and calculating system relates to LAN dispatching monitoring and management field. Including data acquisition module selects node from LAN and gathers electric power instantaneous quantity data, data processing module carries out screening, analysis and operation to the instantaneous quantity of gathering, including: through the calculation of total output of self -generation of reverse method, according to the total output of self -generation with the main force self -generation plant output data that has gathered, calculates the secondary self -generation plant output, to chain type line structure, through two end substation data calculation line inner power generation and load balance value as approximate power output, to tree shape line structure, through main line data subtracts public power plant and public load data and obtains self -generation output, centralized display module shows instantaneous quantity data after data processing module processing in same monitoring interface, has promoted data acquisition efficiency, has strengthened data timeliness and accuracy, has optimized dispatching decision, has improved power grid operation reliability.

The present application provides a kind of training method, device, electronic equipment and storage medium of pedestrian search model based on twin network, wherein the method comprises: determining training image;According to the lower branch of twin network, the feature of training image is extracted, and the feature vector of each pedestrian in training image is obtained;The training image is processed to obtain multi-scale pedestrian image, and the feature of multi-scale pedestrian image is extracted according to the upper branch of twin network, and the multi-scale feature vector of each pedestrian in training image is obtained;According to the feature vector and multi-scale feature vector, training is carried out, and the trained pedestrian search model is obtained when training is completed. When pedestrian search is carried out, the pedestrian at different scales is accurately searched.
