Adaptive sampling technique for selecting negative examples for artificial intelligence applications
First Claim
1. Processing apparatus adapted to implement an artificial intelligence application, which application requires use of training sets having positive and negative examples, the apparatus comprising:
- at least one memory adapted to store data and/or instructions;
at least one processor adapted to execute the following operations, using the at least one memory;
recognizing and maintaining a set of positive examples for training; and
upon completion of recognition of the set of positive examples, selecting a set of negative examples for training responsive to the set of positive examples.

Abstract
Artificial intelligence applications require use of training sets containing positive and negative examples. Negative examples are chosen using distributions of positive examples with respect to a dominant feature in feature space. Negative examples should share or approximately share, with the positive examples, values of a dominant feature in feature space. This type of training set is illustrated with respect to content recommenders, especially recommenders for television shows.

10. Apparatus adapted to implement an artificial intelligence application, which application requires use of training sets having positive and negative examples, the positive and negative examples being describable in accordance with at least one feature, the feature having a plurality of possible values within a feature space, the apparatus comprising:
-
at least one memory adapted to store data and/or instructions;
at least one processor adapted to execute the following operations, using the at least one memory;
recognizing and maintaining a set of positive examples for training, the set of positive examples including at least one subset, each subset including a respective plurality of members sharing a same respective value of a given feature in the feature space, the given feature being one that has been determined in advance to be a dominant feature in the feature space; and
selecting a set of negative examples for training, the set of negative examples including at least one respective subset corresponding to the at least one subset of the set of positive examples, the members of each respective subset of negative examples being selected to share the same respective value of the given feature with the members of the subset of the set of positive examples that corresponds with the respective subset of negative examples. - View Dependent Claims (11, 12, 13, 14, 15, 17, 18, 19, 20)

16. Apparatus adapted to implement an artificial intelligence application, which application requires use of training sets having positive and negative examples, the positive and negative examples being describable in accordance with at least one feature, the feature having a plurality of possible values within a feature space, the apparatus comprising:
-
at least one memory adapted to store data and/or instructions;
at least one processor adapted to execute the following operations, using the at least one memory;
recognizing and maintaining a set of positive examples for training, the set of positive examples including at least one subset, each subset including a plurality of members sharing a same respective value of a given feature in the feature space, the given feature being one that has been determined in advance to be a dominant feature in the feature space; and
selecting a set of negative examples for training, the set of negative examples includes at least one respective subset of negative examples, the members of the respective subset of negative examples being selected to have a value of the given feature that lies within a predetermined range of the same respective value, but not including the same respective value.
