Finally, the system outputs a result of the A/B test for use in assessing an effect of a treatment variant in the A/B test on the service-level metrics.

Abstract: Techniques for ensuring differential privacy in top-K selection are provided. In one technique, multiple items and multiple counts are identified in response to a query. For each count, which corresponds to a different item, a noise value is generated and added to the count to generate a noisy value, and the noisy value is added to a set of noisy values that is initially empty. A particular noise value is generated for a particular count and added to the particular count to generate a noisy threshold. The particular noise value is generated using a different technique than the technique used to generate each noise value in the set. Based on the noisy threshold, a subset of the noisy values is identified, where each noisy value in the subset is less than the noisy threshold. A response to the query is generated that excludes items that correspond to the subset.

Abstract: During operation, a system obtains a graph that includes a set of nodes representing users in an online network and a set of edges representing relationships or interactions between pairs of the nodes. Next, the system selects egos containing a subset of the users that are representative of a distribution of an attribute across the users. The system then generates clusters of users, such that each cluster contains an ego and alters selected from the ego's connections in the graph. The system further divides the clusters between a treatment group and a control group, exposes alters in the treatment group to a treatment variant of an A/B test, and exposes alters in the control group to a control variant of the A/B test. Finally, the system outputs a result of the A/B test.

Abstract: This disclosure describes techniques for verifying compatibility of NOS image versions during startup of one or more hardware modules of a distributed router system. A client-server transaction protocol is executed between a communication server and a communication client configured according to the protocol to run on hardware modules of a distributed router system. A communication client discovers a communication server through a handshake transaction and sends a software image signature of an NOS image version. The communication server forwards the software image signature to an NOS verification server to determine whether the software image signature is compatible.

Abstract: Computer-implemented techniques for ex post facto accounting for interference from network effects in a one-to-one messaging experiment in an online service. With the techniques, is not necessary to identify isolated, non-interacting communities of users pre-experiment. Instead, unconventionally, a total lift for the treatment feature may be computed post-experiment based on the observed actual messages sent during the experiment by users in the treatment and control groups. Techniques for post-experiment computation of an experiment-specific message response rate, based on observed messages sent, and post-experiment computation of an instant lift, based on overserved message sent, are also disclosed.
