Latest Patents

Bottou's latest patents include the "Parallel Support Vector Method and Apparatus" and the "Method and Apparatus for Transductive Support Vector Machines." The first patent discloses an improved technique for training a support vector machine using a distributed architecture. In this method, a training data set is divided into subsets, which are optimized in a first level of optimizations, generating a support vector set. These sets are then combined and used as input for a second level of optimizations, continuing this hierarchical processing for multiple levels. This approach ensures a global optimal solution by allowing feedback from the final set of support vectors back into the first level of optimization, iterating until convergence is achieved.

The second patent focuses on training a transductive support vector machine using both labeled training data and unlabeled test data. It involves decomposing a non-convex objective function into a convex function and a concave function. By calculating a local approximation of the concave function at a hyperplane and combining it with the convex function, Bottou's method transforms the problem into a convex one, which is then solved iteratively until convergence.
