Methods for performing genetic algorithm-based feature selection are provided herein. In certain embodiments, the methods include steps of applying multiple data splitting patterns to a learning data set to build multiple classifiers to obtain at least one classification result; integrating the at least one classification result from the multiple classifiers to obtain an integrated accuracy result; and outputting the integrated accuracy result to a genetic algorithm as a fitness value for a candidate feature subset, in which genetic algorithm-based feature selection is performed.

摘要:
A system facilitates and enhances review of one or more multimedia input streams that includes some combination of video, audio and text information, generating a multimedia summary, thereby enabling a user to better browse and/or decide on viewing the multimedia input streams in their entirety. The multimedia summary is constructed automatically, based in part on system specifications, user specifications and network and device constraints. In a particular application of the invention, the input multimedia streams represent news broadcasts (e.g., television news program, video vault footage). In such a particular application, the invention can enable the user to automatically receive a summary of the news stream in accordance with previously provided user preferences and in accordance with prevailing network and user device constraints.
