32 results about "Multilevel model" patented technology

Multilevel models (also known as hierarchical linear models, linear mixed-effect model, mixed models, nested data models, random coefficient, random-effects models, random parameter models, or split-plot designs) are statistical models of parameters that vary at more than one level. An example could be a model of student performance that contains measures for individual students as well as measures for classrooms within which the students are grouped. These models can be seen as generalizations of linear models (in particular, linear regression), although they can also extend to non-linear models. These models became much more popular after sufficient computing power and software became available.

Consumption experience system with advertisement playing

InactiveCN106033580ALong playing timeImprove input effectMarketingInput/output processes for data processingMultilevel modelMultilevel queue
The invention discloses a consumption experience system with advertisement playing. A menu system comprises a multilevel menu. Parts of the levels of the menu in the multilevel menu are a shopping menu. Each level of menu is provided with a display portion and a first command portion which can enters into the next level of the menu. The display portion calls corresponding data in a database so as to display a content in the level of the menu. A menu system signal is connected to a man-machine interaction module so that a user can select to operate the first command portion. Each level of menu calls a timing module so as to determine whether non-operating time of the man-machine interaction module exceeds predetermined time. If the non-operating time exceeds the predetermined time, advertisement data in the database is called to be played and predetermined time of each level of menu in the multilevel menu is gradually increased from a front portion to a back portion. During an advertisement playing process, whether the user triggers the menu system through the man-machine interaction module is determined. If the user triggers the menu system, a first level of menu is entered into. The system possesses advantages that an advertisement investment effect is good; a design is humanized and client privacy leakage can be avoided.
