Abstract: A computer-implemented technology for planning routes is described herein. In accordance with one aspect, travel data of commuters of a transportation network are provided. Continuous distributions of travel time and waiting time are generated from the travel data. The continuous distributions of travel time and waiting time are associated to a transportation graph of the transportation network. The transportation graph includes nodes corresponding to stops of the transportation network and edges interconnecting the nodes. Travel time and waiting time are associated as costs of the edges in the transportation graph. In response to receiving input parameters, expected costs of candidate routes in the transportation graph are determined in accordance with a modified multi criteria shortest path technique. The modified multi criteria shortest path technique invokes a subroutine to retrieve accurate costs of routes based at least on the costs of the edges in the transportation graph. Route recommendations are provided based on the expected costs of the candidate routes.

Abstract: Described is a system, a method, and a computer-implemented apparatus for increasing computational efficiency and capacity of data stream processing systems. In one embodiment, executor grouping reduces cross-socket communication in a Non-Uniform Memory Access (NUMA) system. In another embodiment, input batching reduces thread context switches which improves instruction cache performance.

Abstract: Described herein is a machine learning framework for facilitating engagements. In accordance with one aspect of the framework, a machine learning model is trained based on the training data. A recommendation associated with an opportunity record may then be generated using the trained machine learning model. Results of one or more actions performed in response to the recommendation may be collected and fed back to the machine learning model to be used as the training data.

Abstract: Jumbo query plans are generated by applying at least one sharing technique and combining at least two of the pattern queries. Costs of the jumbo query plans may then be estimated and used to search for an optimal query plan. The optimal query plan may then be executed on an input data stream to generate an output data stream.
