  • Patent number: 12236182
    Abstract: A user experience repository may contain base layouts and variant metadata for applications of an enterprise. An application design platform may receive, from a designer, an indication of a selected base layout for a selected application and interact with the designer to create a user experience variant (e.g., a page layout). The designer may then define an assignment rule for the user experience variant, the assignment rule including custom logic and multiple user parameters (e.g., a user role, country, language, etc.), and the system may store information about the user experience variant and assignment rule. An enterprise application service platform may determine that a user is accessing the selected application and evaluate the custom logic of the assignment rule based on user parameters of the user accessing the selected application. In accordance with the evaluation, the system may arrange to provide the appropriate user experience variant to the user.

  • Patent number: 12165671
    Abstract: Techniques for performing conversation recovery of a system/user exchange are described. In response to determining that an action responsive to a user input cannot be performed, a system may determine a topic to recommend to a user. The topic may be unrelated to the original substance of the user input. The system may have access to various data representing a context in which a user provides an input to the system. The system may use these inputs and various data at runtime to make a determination regarding whether a user should be recommended a topic, as well as what that topic should be. The system may cause a question be output to the user, with the question asking the user about the topic, for example whether the user would like a song played, whether the user would like to hear information about a particular individual (e.g., artist), whether the user would like to know about a particular skill (e.g.

  • Publication number: 20240331032
    Abstract: An example system creates a video based on a user's financial profile for a specified time period and displays the video on a virtual reality device to help the user visualize the user's financial decisions resulting in the user's current financial status as well as visualize the user's predicted financial status in the future. The system analyzes the user's historical financial transactional data, profile information and relevant market and peer information to extract and predict one or more data points regarding the user's financial profile from the past, present and the future. The system generates a video about the user's financial profile by creating a storyline based on the one or more data points.

  • Patent number: 12102963
    Abstract: A high salinity feed water such as seawater is treated to produce a reverse osmosis (RO) concentrate and an RO permeate. Optionally, some or all of the RO concentrate may be filtered to produce a nanofiltration (NF) permeate. Optionally, some feed water can also be filtered to produce NF permeate without first being concentrated by RO treatment. The NF permeate, or a blend of the RO permeate and NF permeate, may be used to produce a product water for injection into an oil-bearing reservoir to enhance oil recovery. Optionally, the product water may have salinity greater than the feedwater, or at least 30 g/L. The product water may have hardness of less than 20 mg/L.

  • Patent number: 12080281
    Abstract: Exemplary embodiments relate to a system for recovering a conversation between a user and the system when the system is unable to properly respond to a user's input. The system may process the user input and determine an error condition exists. The system may query one or more storage systems to identify candidate text data based on their semantic similarity to the user input. The storage systems may store data related to past frequently entered inputs and/or user-generated inputs. Alternative text data is selected from the candidate text data, and presented to the user for confirmation.

  • Publication number: 20240264467
    Abstract: An ophthalmic lens for myopia control comprising patterns or masks which block and/or attenuate light (e.g., by amplitude modulation). The amplitude modulation may be binary, for example, where zero amplitude means absorption or blocking of light and a value of one means that light may be transmitted through the lens without change (e.g., without significant change). Alternatively, in some embodiments, the amplitude modulation may not be binary.

  • Publication number: 20240249187
    Abstract: Provided are techniques for correcting a classification model. For each original record of a plurality of original records that are processed by a classification model: the original record is perturbed; for the original record, an original confidence value is obtained for each class of a plurality of classes; for the perturbed record, a perturbed confidence value is obtained for each class of the plurality of classes; a final confidence value is determined using each original confidence value, each perturbed confidence value, and a direction of distance travelled; and a determination is made of whether the original record is biased based on the final confidence value. Then, it is determined whether the classification model is biased based on the original records that are determined to be biased. In response to determining that the classification model is biased, the classification model is corrected, otherwise, the classification model is deployed.

  • Patent number: 12014287
    Abstract: A system and related method score a fairness of an outcome model. The method comprises receiving a set of original transaction records (OTRs), and selecting an OTR subset of the OTRs according to a subset selection criteria in order to reduce a number of OTRs to send to outcome model. For each OTR in the subset a perturbed transaction record (PTR) is created based on the OTR that includes changing at least one attribute in the PTR from the OTR, sending the OTR and the PTR to the outcome model, receiving an OTR outcome and a PTR outcome from the outcome model, and determining a record bias score for the OTR outcome and the PTR outcome respectively that indicates bias in the respective outcome. The OTR and the PTR bias score are stored in a bias determination system (BDS) database.

  • Patent number: 12008366
    Abstract: Early indications of application programming interface (API) usage are identified by correlation to particular issues with the API including singular and mutual consistency, completeness, accuracy, and staleness. Analysis of API input and output along with data type and formatting information facilitates identification of the API issues. Establishing a correlation between API usage and issues supports early detection of potential usage reduction on a case-by-case level. Corrective action to resolve identified issues may be performed in a timely manner to maintain usage levels.

    Abstract: One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to a process to facilitate abnormal document self-discovery. A system can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components can comprise a fairness component, an identification component, a removal component, and an evaluation component. The fairness component can receive a dataset for a tree-based model and calculates a first fairness, and the identification component can identify root to leaf paths in the tree-based model for one or more records of the dataset and one or more corresponding perturbed records. The removal component can remove at least one record of the one or more records having similar root to leaf paths to the other records of the one or more records.
