Abstract
Techniques are disclosed for multi-modal identification that utilize a classifier combination framework. One embodiment of the present invention provides a multi-modal identification system that includes a collection of classifiers that classify feature streams derived from audio and/or video sources. A classifier combination scheme is used to combine the classifier outputs having varying degrees of confidence, but in a robust way by using a confidence-based weighting scheme that operates on a “per-class” basis, rather than (or in addition to) the traditional “per-classifier” basis. The system can be distributed across several machines running independent feature classifiers on the subscription basis.
