  • Patent number: 11886230
    Abstract: A computer-implemented system and method for predicting and flagging an anomaly entered in a digital form. A server computing device classifies a plurality of data fields of the digital form to identify a set of non-zero value data fields; and obtains an anomaly detection model comprising a statistical tree structure associated with the data field of the digital form. The server computing device receives datasets including a target value of a data field and values of a set of cohorting data features; traverses a statistical tree structure of the anomaly detection model with the target dataset to form a set of target cohorts to determine a target statistic value for the data field; flags the data field value of the target dataset as an anomaly item; and generates one or more confidence scores for a runtime prediction based on one or more variance changes for the data field.

  • Publication number: 20230113607
    Abstract: A method including transcribing, into digital tokens, utterances from a conversation between an agent and a person. The method also includes embedding the digital tokens into an utterances tensor including sequences of the digital tokens. The method also includes obtaining a metadata tensor by encoding metadata related to the utterances into the metadata tensor. The method also includes executing a machine learning model which takes, as input, the utterances tensor and the metadata tensor, and which outputs a predicted source article predicted to be related to the utterances. The method also includes generating an interactive link to the predicted source article.

  • Publication number: 20230030405
    Abstract: A processor may receive a call transcript including text and form a text string including at least a portion of the text. The processor may generate a situation description of the call transcript, which may comprise processing the text string using a transformer-based machine learning model. The processor may generate a trouble description of the call transcript, which may comprise creating a sentence embedding of the situation description, creating sentence embeddings for a plurality of utterances within the portion of the text, determining respective similarities between the sentence embedding of the situation description and each of the sentence embeddings for each respective one of the plurality of utterances, and selecting at least one of the plurality of utterances having at least one highest determined respective similarity as the trouble description. The processor may store a call summary comprising the situation description and the trouble description in a non-transitory memory.

  • Publication number: 20230036688
    Abstract: A method implements calibrated risk scoring and sampling. Features are extracted from a record. A risk score, associated with the record, is generated from the features using a machine learning model. The record is mapped to a risk bucket using the risk score. The risk bucket may include multiple risk bucket records. The record is selected from the risk bucket records with a sampling threshold corresponding to the risk bucket. A form prepopulated with values from the record is presenting to a client device.

  • Patent number: 11556716
    Abstract: Systems and methods may be used to generate and use intent predictions to enhance user experience. The intent predictions may describe the data required to resolve a user request included in a user input (e.g., question, search query, and the like) submitted by a user. The intent predictions may be generated using a machine learning model that comprises a model framework for extracting features and classifying user inputs into intent classes based on the extracted features. The intent predictions may be integrated into an information service to improve business metrics including contact rate, transfer rate, helpful rate, and net total promoter score.

  • Publication number: 20210406913
    Abstract: A method may include receiving an unstructured question from a user having structured contextual features. The unstructured question may include tokens. The method may further include converting, using a sentence embedding model, the tokens to a question vector, assigning the question vector to a question cluster, assigning, by applying a user clustering model to the question cluster and the structured contextual features, the user to a user cluster, and assigning, using a trained machine learning model, a channel to the user cluster. The channel may be used to communicate with a customer service agent for a management application. The trained machine learning model may assign, using metrics, a channel to each user cluster. The method may further include recommending, based on assigning the channel to the user cluster, the channel to the user for the question.

  • Publication number: 20210049452
    Abstract: An anomaly detection service executed by a processor may receive multivariate time series data and format the multivariate time series data into a final input shape configured for processing by a generative adversarial network (GAN). The anomaly detection service may generate a residual matrix by applying the final input shape to a generator of the GAN, the residual matrix comprising a plurality of tiles. The anomaly detecting service may score the residual matrix by identifying at least one tile of the plurality of tiles having a value beyond a threshold indicating an anomaly. The processor may perform at least one remedial action for the anomaly in response to the scoring.
