Abstract
Techniques for performing unequal sampling are provided. In one technique, multiple scores generated by a prediction model are identified, each score corresponding to a different entity of multiple entities. Multiple buckets are determined, each bucket corresponding to a different range of scores. Each entity is assigned to a bucket based on the score corresponding to the entity. A probability distribution function is generated based on the scores and a number of scores belonging to each bucket. For each entity, a probability of sampling the entity is determined based on the probability distribution function and a score corresponding to the entity. A subset of the entities are sampled based on the probability determined for each entity.
