Target detection model training method and device, storage medium and computer equipment

The invention relates to a target detection model training method and device, a computer readable storage medium and computer equipment, and the method comprises the steps: obtaining a feature map ofa sample image during training, and determining an initial detection box in the feature map according to a preset rotation angle, a preset scale and a preset target aspect ratio; adjusting the position of each initial detection frame to obtain the position information of the prediction detection frame, and adjusting the network parameters of the regression network according to the position information and the real position information in the annotation information of the sample image; predicting the prediction probability of the target corresponding to each preset category according to the target detection area determined by the position information of the prediction detection frame; and adjusting the network parameters of the classification network according to the real category information in the annotation information of the sample image and the prediction probability, and then obtaining a target detection model used for performing target detection on the image. According to the scheme provided by the invention, the target detection model can identify the rotation angle of the target in the image, and the positioned target detection frame is more accurate.

An integration method of multiple prediction results of power load probability density

The invention relates to an integration method of multiple prediction results of power load probability density, and belongs to the technical field of power system analysis. According to the method, aplurality of probability density or quantile probability prediction models are obtained through training of a plurality of three-class regression models set by different hyper-parameters, and the output of the quantile prediction models is converted into a probability density model conforming to Gaussian distribution through Gaussian distribution assumption of loads and a least square method. A probability density prediction integration method is adopted, a probability density prediction optimal integration model is constructed based on the trained probability density prediction model and result, the weights of different probability density prediction methods are determined, and therefore the probability loss of the continuous grade of the final integration prediction model is minimum. The method is finally converted into a quadratic programming problem, the global optimal integrated weight is quickly searched by utilizing mature commercial software, the probability density short-termload prediction precision is improved, and the dispatching operation cost of the power system is further reduced.

Mobile banking security authentication method

The invention discloses a mobile banking security authentication method. The mobile banking security authentication method comprises the following steps: A, a client uses a client terminal to request for access to an application server; B, the application server requests an authentication server to authenticate the client identity; C, the authentication server requires authentication information from the client terminal; D, a dynamic two-dimension code password token generates a dynamic two-dimension code containing own account and password information; E, the dynamic two-dimension code on a token screen is scanned and transmitted to the authentication server through the network; F, the authentication server invokes corresponding client information, generates a random sequence relevant to client information and events, analyzes the two-dimension code password for comparison in order to distinguish the legitimacy and authenticity of the client identity, and reports the authentication result to the application server; G, the application server feeds back the authentication result to the client terminal, and determines provision of service or denial of service. The mobile banking security authentication method combines the dynamic password token and the two-dimension code, provides double-factor strong identity authentication, and provides guarantee for mobile banking security.

An integrated method for multiple prediction results of electric load probability density

The invention relates to an integration method of multiple prediction results of electric load probability density, belonging to the technical field of power system analysis. The present invention obtains a plurality of probability densities or quantile probability prediction models through the training of three types of regression models set by multiple sets of different hyperparameters, and converts the output of the quantile prediction models into obedience A probability density model for a Gaussian distribution. Using the integrated method of probability density prediction, the optimal integrated model of probability density prediction is constructed based on the trained probability density prediction model and results, and the weights of different probability density prediction methods are determined, so that the continuous level probability loss of the final integrated prediction model is minimized. This method is finally transformed into a quadratic programming problem, and then the global optimal integration weight is quickly searched by mature commercial software, which improves the accuracy of short-term load forecasting based on probability density and reduces the operating cost of power system dispatching.
