Patent number: 11860971Abstract: According to an embodiment of the present invention, an approach accurately detects anomalies or outliers of a time-series dataset. A method for identifying whether a particular data element of the time-series dataset is an outlier comprises predicting a value for that particular data element and obtaining a threshold value that defines, relative to the predicted value, whether an actual value of the data element is an outlier. In an aspect of a present invention embodiment, the threshold value is generated based on historic error values associated with data elements temporally preceding the particular data element of the time-series dataset.Type: GrantFiled: May 24, 2018Date of Patent: January 2, 2024Assignee: International Business Machines CorporationInventors: Teodora Buda, Hitham Ahmed Assem Aly Salama, Bora Caglayan, Faisal Ghaffar

Patent number: 10776886Abstract: A method, computer system, and a computer program product for improving social media network actions is provided. The present invention may include determining a proposed action by a user and predicting a predicted influence score for the proposed action. The present invention may include identifying a prior related action in the user's social media network. The present invention may include retrieving a previously calculated average influence score for the type and user of the prior related action and applying a decay profile to the average influence score from the time of the action to a current time. The present invention may include comparing the predicted influence score with the decayed average influence score at the current time. The present invention may include posting the proposed action on the social media network at a time when the predicted influence score is greater than the decayed average influence score.Type: GrantFiled: November 8, 2018Date of Patent: September 15, 2020Assignee: International Business Machines CorporationInventors: Faisal Ghaffar, Teodora S.
