METHODS 1,028 previously unanalyzed patients were used to externally validate the prognostic criteria for overall survival (OS). The model's(More)
We discuss several strategies to implement Dykstra’s projection algorithm on NVIDIA’s compute unified device architecture (CUDA). Dykstra’s algorithm is the central step in and the computationally most expensive part of statistical multi-resolution methods. It projects a given vector onto the intersection of convex sets. Compared with a CPU implementation(More)
