摘要： User behavior analysis method and device are disclosed. The method comprises: obtaining a behavior record of users regarding commodities; acquiring, by determining a commodity feature vector in a predetermined commodity feature space of each of the commodities, a commodity feature matrix consisting of the commodity feature vectors of the commodities; for each of the users, calculating, based on a sub behavior record of the corresponding user regarding each of the commodities, a preference score of the corresponding user regarding each of the commodities, so as to get a score matrix composed of the preference scores of the users regarding the commodities; and for each of the users, determining, based on a regularized least squares based solution of a difference function of the score matrix and a prediction matrix, a user feature vector of the corresponding user in its related predetermined commodity feature space.

摘要： Disclosed is a control method of controlling an air conditioning system. The control method comprises steps of obtaining plural adjustment parameter groups of each of plural air conditioners contained in the air conditioning system; acquiring at least one desired environmental parameter of each of one or more control targets; selecting, based on the desired environmental parameters, one from the plural adjustment parameter groups of each of the plural air conditioners to serve as a target adjustment parameter group of the corresponding air conditioner; and respectively transmitting the plural target adjustment parameter groups to the plural air conditioners, so that the plural air conditioners respectively set their adjustment functions according to the plural target adjustment parameter groups.

摘要： A method for generating determination indexes for identifying ECG interfering signals includes acquiring ECG signals to obtain a sequence of data values representing original ECG signals; dividing the sequence of data values acquired during a period of time into groups and collecting all the minimum data values in their respective groups on a statistical basis; determining the minimum and the maximum data values in a minimum set made up of all the minimum data values in their respective groups; and using the difference between the minimum and the maximum data values as a first baseline drift determination index to identify at least one of low frequency interference and irregular interference
