FAST ORTHOGONAL PROJECTION

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for efficiently performing linear projections. In one aspect, a method includes actions for obtaining a plurality of content items from one or more content sources. Additional actions include, extracting a plurality of features from each of the plurality of content items, generating a feature vector for each of the extracted features in order to create a search space, generating a series of element matrices based upon the generated feature vectors, transforming the series of element matrices into a structured matrix such that the transformation preserves one or more relationships associated with each element matrix of the series of element matrices, receiving a search object, searching the enhanced search space based on the received search object, provided one or more links to a content item that are responsive to the search object.

1. A computer-implemented method comprising:
obtaining a plurality of content items; extracting a plurality of features from each of the plurality of content items; generating a feature vector for each of the extracted features in order to create a search space; generating a series of element matrices based upon the generated feature vectors, wherein each element matrix of the series of element matrices is associated with one or more relationships; enhancing the search space at least in part by transforming the series of element matrices into a structured matrix such that the transformation preserves the one or more relationships associated with each element matrix of the series of element matrices; receiving a search object; searching the enhanced search space based on the received search object; and providing one or more links to one or more content items that are responsive to the search object.
