Problems solved by technology
[0004] In the above-mentioned solution for obtaining the predicted value of advertisements provided in the related art, when querying each prediction model, it is necessary to separately generate the feature combination required by the prediction model, which reduces the query efficiency of the predicted value, and the generation of the feature combination The process will inevitably occupy system resources, resulting in increased system overhead and reduced system performance

Embodiment Construction
[0060] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0061] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

The embodiment of the present application discloses a method and an apparatus for obtaining an advertisement prediction value and a terminal. The method for obtaining the advertisement prediction value comprises the following steps: determining a combination of primary features of advertisements in an advertisement candidate queue according to a primary selection model; searching for a key value corresponding to a primary feature combination of the advertisement in a feature buffer pool; If found, querying the primary selection model to obtain a primary selection prediction value of the advertisement; selecting a predetermined number of advertisements in the advertisement candidate queue to form a selected candidate queue; Predicted values of candidate advertisements in the selected candidate queue are obtained by a selected model. The invention can cache the key value corresponding to the feature combination of the advertisement at the request level, and is convenient to use quickly.Therefore, when querying each prediction model, the invention does not need to obtain the key value corresponding to the feature combination separately for each prediction model, thus improving the query efficiency of the advertisement prediction value, reducing the system overhead and improving the system performance.
Description
technical field [0001] The present application relates to the technical field of the Internet, and in particular to a method, device and terminal for obtaining an advertisement prediction value. Background technique [0002] For advertising or personalized recommendations, or even general Internet products, the most concerned indicator is the click-through rate. Whether it is manual operation or machine decision-making, it is necessary to predict the possible click-through rate of an advertisement or recommended content to judge Which items should be placed in a more important position. [0003] In the existing related technology, for each advertisement, the steps to evaluate the predicted value include: primary cutoff, click-through rate prediction and conversion prediction. Since each prediction needs to use an independent prediction model, for each advertisement , it is necessary to query the prediction model one by one to obtain the prediction value of the advertisement...
