Patent number: 11928634Abstract: Detecting fraudulent activity can be a complex, manual process. In this paper, we adapt statistical properties of count data in a novel algorithm to uncover records exhibiting high risk for fraud. Our method identifies shelves, partitioning data under the counts using a Student's t-distribution. We apply this methodology on a univariate dataset including cumulative results from phone calls to a customer service center. Additionally, we extend this technique to multivariate data, illustrating that the same method is applicable to both univariate and multivariate data.Type: GrantFiled: September 7, 2022Date of Patent: March 12, 2024Assignee: Verint Americas Inc.Inventors: Joseph Wayne Dumoulin, Cynthia Freeman, James DelloStritto

Publication number: 20240020589Abstract: Methods and systems for selecting a forecasting algorithm to use for a forecast for a time interval are provided. A class is a series of time intervals that is selected by an entity from time series data that relates to external data or is a series of time intervals from the time series data that corresponds to a motif. The time series data is processed by a computer to identify motifs, and classes are generated based on each identified motif. A user may further identify one or more classes in the time series data. For each class, the forecasting algorithm that best predicts the historical demand data for time intervals associated with the class is determined. Later, when the entity desires to receive a forecast for a future time interval, the class associated with the future time interval is determined. The forecasting algorithm determined to best predict demand for the determined class is then used.Type: ApplicationFiled: July 13, 2022Publication date: January 18, 2024Inventors: Jonathan Silverman, Nicholas Mortimer, Cynthia Freeman

Publication number: 20240020545Abstract: The present disclosure describes methods and systems for selecting the forecasting algorithm to use for a prediction based on motifs. A motif is a pattern of interval values that is found to repeat in time series data. Time series data that includes historical demand data (e.g., average communication volume) for an entity at various time intervals in the past is received. The time series data is processed to identify motifs. For each identified motif, the forecasting algorithm that best predicts the historical demand data for time intervals associated with the motif is determined. Later, when the entity desires to receive a forecast for a future time interval, the motif associated with the future time interval is determined. The forecasting algorithm determined to best predict demand for the determined motif is then used to predict the demand for the future time interval.Type: ApplicationFiled: July 13, 2022Publication date: January 18, 2024Inventors: Jonathan Silverman, Nicholas Mortimer, Cynthia Freeman

Patent number: 11868732Abstract: This disclosure describes techniques and architectures for evaluating conversations. In some instances, conversations with users, virtual assistants, and others may be analyzed to identify potential risks within a language model that is employed by the virtual assistants and other entities. The potential risks may be evaluated by administrators, users, systems, and others to identify potential issues with the language model that need to be addressed. This may allow the language model to be improved and enhance user experience with the virtual assistants and others that employ the language model.Type: GrantFiled: August 8, 2022Date of Patent: January 9, 2024Assignee: Verint Americas Inc.Inventors: Cynthia Freeman, Ian Beaver

Patent number: 11704477Abstract: Attention weights in a hierarchical attention network indicate the relative importance of portions of a conversation between an individual at one terminal and a computer or a human agent at another terminal. Weighting the portions of the conversation after converting the conversation to a standard text format allows for a computer to graphically highlight, by color, font, or other indicator visible on a graphical user interface, which portions of a conversation led to an escalation of the interaction from an intelligent virtual assistant to a human customer service agent.Type: GrantFiled: June 28, 2021Date of Patent: July 18, 2023Assignee: Verint Americas Inc.Inventors: Ian Roy Beaver, Cynthia Freeman, Jonathan Patrick Merriman, Abhinav Aggarwal

Publication number: 20230177030Abstract: Disclosed are a framework and method for selecting an anomaly detection method for each of a plurality of class of time series based on characteristics a time series example that represents an expected form of data. The method provides classification of a given time series into one of known classes based on expected properties of the time series, filtering the set of possible detection methods based on the time series class, evaluating the remaining detection methods on the given time series using the specific evaluation metric and selecting and returning a recommended anomaly detection method based on the specific evaluation metric.Type: ApplicationFiled: January 30, 2023Publication date: June 8, 2023Inventors: Ian Roy Beaver, Cynthia Freeman, Jonathan Merriman

System and method for determining reasons for anomalies using cross entropy ranking of textual items
Patent number: 11610580Abstract: A framework for reducing the number of textual items reviewed to determine the source of or reason for an anomaly in a time series that is used to track metrics in textual data is provided. According the framework, textual items in a time window corresponding to the anomaly are ranked according to the cross-entropy as determined by applying a language model to the relevant textual items and ranking textual items that most likely triggered an anomaly in time series data based on the cross-entropy value. In an aspect, a predetermined number of textual items having the highest cross-entropy are provided or all textual items having cross-entropy value higher than predetermine threshold are provided.Type: GrantFiled: March 5, 2020Date of Patent: March 21, 2023Assignee: Verint Americas Inc.Inventor: Cynthia Freeman -
Patent number: 11593713Abstract: Systems and methods are provided framework for automatically choosing the appropriate generalized linear model (GLM) given a time series of count data, and for anomaly detection on time series data. A dispersion parameter is determined and used to determine whether the count data is overdispersed data or underdispersed data. The overdispersed data or the underdispersed data is used to determine a GLM to apply on the dataset. Using the determined GLM on the data, anomalies can be determined.Type: GrantFiled: June 10, 2020Date of Patent: February 28, 2023Assignee: Verint Americas, Inc.Inventor: Cynthia Freeman
