Systems, methods and/or computer program products for controlling and visualizing topic modeling results using a topic modeling interface. The interface allows user directed exploration, understanding and control of topic modeling algorithms, while offering both semantic summaries and/or structure attribute explanations about results. Explanations and differentiations between results are presented using metrics such as cohesiveness and visual displays depicting hierarchical organization. Through user-manipulation of features of the interface, iterative changes are implemented through user-feedback, adjusting parameters, broadening or narrowing topic results, and/or reorganizing topics by splitting or merging topics. As users trigger visual changes to results being displayed, users can compare and contrast output from the topic modeling algorithm. With each change to parameters, users view different explanations informing the user why the changes being displayed occurred, providing users deeper understanding of the topic modeling process, how to manipulate parameters to achieve accurate topic results and adjust granularity of information presented.

Transparent and controllable topic modeling

A device, system, and a computer-implemented method a for identifying an anomaly in an operation of a device includes comparing, by an electrical power analyzer, a current power draw signature of the device with a known power draw signature of the device. There is a determining as to whether at least one anomaly is present in the current power draw signature. A warning is generated in response to determining the at least one anomaly is present in the current power draw signature.
