Abstract
A computing system classifies distributed data. A first computation request is sent to worker computing devices. A first response is received from each worker computing device. Each first response includes a first matrix computed as a second order derivative of a logarithm of a predefined likelihood function on a subset of training data distributed to each respective worker computing device. A global first matrix is defined by concatenating the first matrix from each worker computing device. A kernel matrix is computed using the training data and a predefined kernel function. A second computation request is sent to the worker computing devices. The second computation request indicates that each worker computing device compute a classification probability for each observation vector distributed to a respective worker computing device using the defined global first matrix and the computed kernel matrix. The determined classification probability is output for each observation vector.
