DETERMINATION OF A BASIS FOR A NEW DOMAIN MODEL BASED ON A PLURALITY OF LEARNED MODELS
First Claim
1. A method, in a machine learning system comprising a plurality of learned models uniquely corresponding to a plurality of domains, for determining which of the plurality of learned models to use as a basis for a new domain model, the method comprising:
- determining, by a processing device, statistical characteristics of features in new domain input to provide new feature statistical characteristics, wherein the new domain input is provided for training the new domain model;
comparing, by the processing device, the new feature statistical characteristics with statistical characteristics of at least some of the plurality of learned models; and
identifying, by the processing device, at least one learned model of the plurality of learned models as the basis for the new domain model when the new feature statistical characteristics compare favorably with the statistical characteristics of the features in the prior input corresponding to the at least one learned model.

Abstract
In a machine learning system in which a plurality of learned models, each corresponding to a unique domain, already exist, new domain input for training a new domain model may be provided. Statistical characteristics of features in the new domain input are first determined. The resulting new domain statistical characteristics are then compared with statistical characteristics of features in prior input previously provided for training at least some of the plurality of learned models. Thereafter, at least one learned model of the plurality of learned models is identified as the basis for the new domain model when the new domain input statistical characteristics compare favorably with the statistical characteristics of the features in the prior input corresponding to the at least one learned model.
