In contrast to previous approaches, we use a full Bayesian model without any sparse approximation techniques, which allows for learning in sub-quadratic and classification in constant time. To handle the additional model flexibility induced by parameterized kernels, our approach is able to optimize the parameters with large-scale training data. A key ingredient of this optimization is a new efficient upper bound of the negative Gaussian process log-likelihood. Experiments with image categorization tasks exhibit high performance gains with flexible kernels as well as learning within a few minutes and classification in microseconds for databases, where exact Gaussian process inference was not possible before.}, doi = {10.1007/978-3-642-33765-9_7}, groups = {largescale,gaussianprocesses}, keywords = {gaussian processes, histogram intersection kernels, large-scale classification}, url = {https://doi.org/10.1007/978-3-642-33765-9_7}, }
