Abstract: A method, a system, and a computer program product for analyzing data collected during a randomized controlled experiment to determine an effect of variations of digital content. Determination of the effect includes execution of first and second testing sequences that prompt responses to first and second digital contents, respectively, from users. The testing sequences execute during a predetermined duration of time. Responses to the first and second testing sequences generate first and second test data, respectively. One or more confidence intervals for each first and second test data are generated at a randomly selected time during the predetermined duration of time. A testing metric indicating the effect of the second digital content over the first digital content is determined at the randomly selected time. The testing metric is determined at any time before expiration of the predetermined duration of time.

Abstract: Certain aspects and features of this disclosure relate to providing anytime-valid confidence sequences for multiple messaging treatments in an experiment. A process controls and/or corrects statistical error when multiple messaging treatments are being evaluated together. Messages can be stored, formatted, and transmitted from a communication server or other computing system. In one example, each test message from among multiple test messages is sent to an independent group of recipients over some period of time. An analytics application programmatically evaluates a metric related to message responses over time and determines a difference in the metric for each of several unique messages as compared to a baseline message. The analytics application also determines a confidence value and can display the changing confidence value in sequence over time along with the current difference, or lift, while maintaining the accuracy of the values.

Abstract: A computer-implemented method includes instantiating a framework configured to optimize a metric of interest for a website based on interactions by participants with instances of a website in a controlled experiment. The instances of the website include one of two variants of digital content. Test data including an estimate of an effect on the metric of interest is generated based on the interactions. A sequence of confidence intervals is dynamically generated while the controlled experiment is ongoing. The true effect and the estimate effect on the metric of interest are both bounded by the sequence of confidence intervals throughout the controlled experiment. As such, an anytime analysis with anytime-valid test data is enabled while the controlled experiment is ongoing.

Abstract: A system is disclosed for identifying and counting typed graphlets in a heterogeneous network. A methodology implementing techniques for the disclosed system according to an embodiment includes identifying typed k-node graphlets occurring between any two selected nodes of a heterogeneous network, wherein the nodes are connected by one or more edges. The identification is based on combinatorial relationships between (k?1)-node typed graphlets occurring between the two selected nodes of the heterogeneous network. Identification of 3-node typed graphlets is based on computation of typed triangles, typed 3-node stars, and typed 3-paths associated with each edge connecting the selected nodes. The method further includes maintaining a count of the identified k-node typed graphlets and storing those graphlets with non-zero counts. The identified graphlets are employed for applications including visitor stitching, user profiling, outlier detection, and link prediction.
