2 results about "Logistic regression" patented technology

The invention discloses a security federated learning logistic regression algorithm. The algorithm comprises the following steps that a host calculates E (WBXB) and sends the E (WBXB) to a gain; a gain calculation calculation calculation calculation E (delta y) = E (yy ') is sent to a host, and then a local model parameter W' A is updated by calculating a gradient value LA; if isstop is not equal to 0, a gradient value LB is calculated, a model parameter E (W 'B) is updated and then the step 1 is repeated: if isstop is equal to 0, the next step enters; guest returns to WA, the host selects a random vector and the W 'B is sent to which disturbance is added to the guest; the guest helps decrypt the W 'B and sends the W' B to the host; and 6, the host returns the model parameter WB. The system architecture provided by the invention can also be easily expanded to support multi-party model training, a joint model can be trained on a large corpus of dispersed data owned by different parties, meanwhile, the privacy of the data is kept, and the precision of the model is ensured.

The invention provides an employee incentive management method, system and device and a storage medium, and the method comprises the steps: screening out brokers meeting a preset condition from a database; obtaining broker features according to brokers; obtaining first broker features, obtaining a total score of the first broker features, and obtaining a plurality of first brokers according to the total score; obtaining multiple second broker features, constructing a recurrent neural network time sequence model according to the logistic regression model and a recurrent neural network algorithm, obtaining the predicted filing trading volume of the brokers, and determining multiple second brokers according to the predicted filing trading volume; obtaining third broker characteristics, sorting brokers according to the third broker characteristics, selecting preset brokers, carrying out sorting according to the filing trading volume of the preset brokers, and obtaining the third brokers according to the sorting result; and respectively exciting the first broker, the second broker and the third broker according to a set rule. The working enthusiasm of employees can be continuously stimulated.
