SPECULATIVE CHECK-INS AND IMPORTANCE REWEIGHTING TO IMPROVE VENUE COVERAGE

摘要

Examples of the present disclosure describe systems and methods for visit detection. More particularly, the described systems and methods relate to improving venue coverage distribution as applied to visit detection models. In aspects, the visit detection system/model of a mobile device may predict that a user is visiting a supervenue based on a set of venue visit probabilities. The visit probability for the supervenue may be redistributed among the subvenues of the supervenue to create a subvenue visit probability distribution. Based on the probability redistribution, the visit detection system/model may predict speculatively that the user is visiting (or has checked into) a particular subvenue. Examples of the present disclosure further described an importance reweighting process may be used to correct the bias in data sets used to train/configure the visit detection system/model.
