Abstract: Disclosed embodiments pertain to determining and communicating purchasing power through a visualization. A trained machine learning model can be invoked on a credit card without a preset limit to predict a dynamic spending limit based on credit card data or credit score data. Purchasing power can be computed as the difference between the dynamic spending limit and a current balance, and a purchase power class can be determined based on the purchasing power. Further, a graphic representation of a purchasing power class can be determined. Subsequently, presentation of the graphic representation can be triggered in a manner that overlays the graphic representation on or around the physical card.

Abstract: An apparatus includes a display, a memory, a light sensor array and a light source array. The light source array emits light to display an image on the display. A controller is configured to receive a sensor output from each light sensor in the light sensor array. An ambient-light illuminance difference between a first illuminance of a first ambient light externally directed onto a first region of the displayed image of the display and a second illuminance of a second ambient light externally directed respectively onto a second region of the displayed image of the display is computed. Light source controls of light sources of the light source array are varied to change a luminous emittance of the light source array within the at least one second region of the displayed image so as to reduce a luminance difference between the first region and the second region of the displayed image.

Abstract: The present disclosure involves systems and methods for identity authentication across multiple institutions using a trusted mobile device as a proxy for a user login. In one example, the operations include identifying a request to trust a particular user associated with a first entity in a digital ID network. A set of personally identifiable information (PII) associated with the user is obtained via the first entity and an identity verification (IDV)/fraud risk analysis is performed. In response to satisfying the analysis, instructions are transmitted to the user to verify the identity via a mobile trust application on an associated mobile device. Upon verification, the mobile device is bound to the user within the digital ID network along with a digital ID associated with the particular user. The digital ID can be used by other entities registered within the digital ID network to authenticate the user.

Abstract: A method is disclosed. The method comprises receiving, by a user device from an identity network computer, a query set comprising a plurality of test identity attributes; encrypting, by the user device, the query set to form an obscured query set; computing, by the user device, a zero-knowledge proof using the obscured query set and an encrypted identity attribute associated with a user operating the user device; and transmitting, by the user device to the identity network computer, the obscured query set and the zero-knowledge proof, wherein the identity network computer verifies the zero-knowledge proof, retrieves an encrypted identity attribute associated with the user, evaluates the obscured query set with respect to the encrypted identity attribute, and transmits a result of the evaluation to a relying party computer.

Abstract: A plurality of flow control nodes are spaced along a production conduit for controlling a flow of formation fluids into the production conduit at different locations in the well. Each flow control node defines a flow path for entry of the formation fluids into the production conduit. A closure is operable to adjust the flow of the formation fluids into the production conduit. A generator at each zone generates electrical power in response to a portion of the flow directed through the generator. An electrical power grid interconnects the plurality of flow control nodes to collectively supply electrical power to the power grid. Each closure and other device components are operable with the electrical power from the power grid.

Abstract: In some aspects, a computing system may iterate between adding spurious data to the dataset and training a model on the dataset. If the model's performance has not dropped by more than a threshold amount, then additional spurious data may be added to the dataset until the desired amount of performance decrease has been achieved. the computing system may determine the amount of impact each feature has on a model's output. The computing system may generate a spurious data sample by modifying values of features that are more impactful than other features. The computing system may repeatedly modify the spurious data that is stored in a dataset. If a cybersecurity incident occurs (e.g., the dataset is stolen or leaked), the system may identify when the cybersecurity incident took place based on the spurious data that is stored in the dataset.

In some embodiments, the candidate questions may be simultaneously presented on the chat interface.

Abstract: In some aspects, a computing system may generate uninformative features that may be added to a dataset of real features to use as a baseline for determining the quality of an explanation of model output. The uninformative features may be features that do not correlate with what a model is tasked with predicting (e.g., the uninformative features may be random values), and the real features may be informative and correlate with what the model is tasked with predicting (e.g., variables of a dataset sample). A machine learning model may be trained on a dataset that includes both the real features and the uninformative features. The computing system may generate feature attributions for model output, which may include feature attributions for the uninformative features and the real features in the dataset.
