Patent ID: 7769763

Claim:
A system, comprising: a repository to store a plurality of instances, each of the instances including a set of features and a label; and at least one device to: generate rules of a model based, at least in part, on weights and conditions formed from combinations of one or more of the features or complements of the features in the repository, identify a new instance, extract the set of features from the new instance, identify which of the rules of the model apply to the new instance based, at least in part, on the extracted features, determine a probability of the label for the new instance based, at least in part, on the weights from which the identified rules were generated, and store information regarding the probability of the label for the new instance, where when generating the rules of the model, the at least one device is to: select a candidate condition, determine the weight for the candidate condition, form a rule based, at least in part, on the candidate condition and the weight, and add the rule to the model.
