  • Patent number: 8463591
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for polynomial mapping of data for linear SVMs. In one aspect, a method includes training a linear classifier by receiving feature vectors and generating a condensed representation of a mapped vector corresponding to a polynomial mapping of each feature vector, the condensed representation including an index into a weight vector for each non-zero component of the mapped vector. A linear classifier is trained on the condensed representations. In another aspect, a method includes receiving a feature vector, identifying non-zero components resulting from a polynomial mapping of the feature vector, and mapping the combination of one or more elements of each non-zero component to a weight in a weight vector to determine a set of weights. The feature vector is classified according to a classification score derived by summing the set of weights.

  • Patent number: 8276190
    Abstract: A user using a browser having stored authentication information for a web service in a first domain is authenticated to a web service in a second domain. The browser is provided with computer program instructions causing the browser to transparently provide the stored authentication information to the service in the first domain, receive cross-domain authentication credentials from the service in the first domain, and provide the cross-domain authentication credentials to the service in the second domain. The service in the second domain validates the cross-domain authentication credentials. If the credentials validate, the service in the second domain transparently provides the user with authenticated access.
