Temporal anomaly detection system and method

A system, comprising:

• one or more computer processors programmed to perform operations comprising:
• obtaining data comprising a history of content presentations by a plurality of publishers on a plurality of client devices;
• calculating a plurality of performance indicators for each publisher based on the data, the performance indicators comprising a measure of user interactions with the content presented by the publisher;
• generating a time history of each performance indicator for each of a plurality of time periods;
• selecting, for each time history, at least one anomaly detector from a plurality of anomaly detectors;
• detecting an anomaly in at least one time history using the selected at least one anomaly detector;
• and
• based on the detected anomaly, facilitating an adjustment of content presentations by the plurality of publishers.

An article, comprising:

• a non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more computer processors, cause the computer processors to perform operations comprising:
• obtaining data comprising a history of content presentations by a plurality of publishers on a plurality of client devices;
• calculating a plurality of performance indicators for each publisher based on the data, the performance indicators comprising a measure of user interactions with the content presented by the publisher;
• generating a time history of each performance indicator for each of a plurality of time periods;
• selecting, for each time history, at least one anomaly detector from a plurality of anomaly detectors;
• detecting an anomaly in at least one time history using the selected at least one anomaly detector;
• and
• based on the detected anomaly, facilitating an adjustment of content presentations by the plurality of publishers.
