Abstract: Implementations identify anomalous events from indexed events. An example system receives s dimension(s) for events, a test start time and a test duration defining a test interval. The system may identify a set of events matching the dimension(s). The set includes events occurring within a test interval or within one of at least two reference intervals. The system generates, for the test interval and the reference intervals, an aggregate value for each unique combination of dimension values in the set of events. The system selects at least one of the unique combination of dimension values for anomaly detection based on a comparison of the aggregate values for the reference intervals and the test interval, and performs anomaly detection on a historical time series for the selected unique combination of dimension values. The system may report any of the selected unique combination of dimension values identified as an anomaly.

One of the methods includes receiving a query prefix from a user. A reference parameter for the user is obtained. One or more likely queries that are likely to co-occur with the reference parameter in user activity sessions are identified, wherein each likely query has an associated prediction score. A ranking of the one or more likely queries is provided in response to receiving the query prefix.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for implementing low-latency differential access controls in a distributed prediction system. One of the methods includes obtaining, by a root server from an authorization server, one or more permitted action types for a requester. A plurality of predicted actions that each co-occur in at least one document with a search parameter are obtained. Any actions having an action type that is not one of the one or more permitted action types for the requester is filtered from the plurality of predicted actions. One or more predicted actions having one of the permitted action types is provided to the requester.
