A method and system are provided for retraining an analytic model. The method includes building, by a processor, a Markov chain for the analytic model. The Markov chain has only two states that consist of an alarm state and a no alarm state. The method further includes updating, by the processor, the Markov chain with observed states, for each of a plurality of timestamps evaluated during a burn-in period. The method also includes updating, by the processor, state transition probabilities within the Markov chain, for each of a plurality of timestamps evaluated after the burn-in period. The method additionally includes generating, by the processor, a signal for causing the model to be retrained, responsive to any of the state transition probabilities representing a probability of greater than 0.5 of seeing the alarm state in a previous interval and again in a current interval.

Optimized re-training for analytic models

In a method for visualizing cyclical patterns in metric data, receiving, by one or more processors, data relating to a computer environment. The method further includes creating, by one or more processors, a visualization, wherein the visualization presents the data in a first format. The method further includes causing, by one or more processors, the visualization to be displayed in a user interface. The method further includes receiving, by one or more processors, an indication of a user interaction in the user interface, wherein the user interaction indicates an alternative visualization of the data, wherein the alternative visualization presents the data in a second format that includes a fragment of the received data. The method further includes creating, by one or more processors, the alternative visualization.

Visualization of cyclical patterns in metric data

A method and system for improving virtual keyboard input is provided. The method includes presenting a GUI comprising a character display portion and a virtual touch screen activated keyboard. The virtual touch screen activated keyboard internally includes currently viewable alphabetical character keys and a free sketch area for entering specialized characters not currently viewable via the virtual keyboard. A selection for an alphabetical character is received via the virtual touch screen activated keyboard and presented via the display portion. A user defined motion sketching a character associated with the specialized characters is detected from a user via the free sketch area. The character is converted into one of the specialized characters and presented to the user.

Virtual keyboard improvement

A computer-implemented method of down-sampling time series data for display is described. The method comprises a step of determining an absolute distance between a previous data point in the series and the present data point, and discarding the present data point if the determined absolute distance is less than a threshold value. The threshold value is dependent on a data value range for the time series data, and a size of a display area within which the time series data is to be displayed.

Data processing

A computer-implemented method for prioritizing an incoming communication directed to a recipient by an originator includes creating a privacy/trust relationship between a recipient and an originator in response to user input, and determining a disposition of an incoming communication by reference to the privacy/trust relationship.
