The Gaussian Q-function is the integral of the tail of the Gaussian distribution; as such, it is important across a vast range of fields requiring stochastic analysis. No elementary closed form is possible, so a number of approximations have been proposed. We use a Genetic Programming (GP) system, Tree Adjoining Grammar Guided GP (TAG3P) with local search(More)
How can we find all connected components in an enormous graph with billions of nodes and edges?Finding connected components is a fundamental operation for various graph computation tasks such as pattern recognition, reachability, graph compression, etc. Many algorithms have been proposed for decades, but most of them are not scalable enough to process(More)
Many real-world data are naturally represented as tensors, or multi-dimensional arrays. Tensor decomposition is an important tool to analyze tensors for various applications such as latent concept discovery, trend analysis, clustering, and anomaly detection. However, existing tools for tensor analysis do not scale well for billion-scale tensors or offer(More)
