Publication number: 20240184984Abstract: Enforcing data ownership may include receiving a request to register an application programming interface (API) endpoint. A plurality of elements of the API endpoint and a target API endpoint may be preprocessed. A distance may be computed for each of element of the API endpoint relative to at least one of the elements of the target API endpoint. A distance score for the API endpoint may be computed based on the distance scores. A term frequency-inverse document frequency (TF-IDF) value may be computed for a plurality of metadata terms of the API endpoint and the target API endpoint. A similarity score between the TF-IDF values of the metadata terms may be computed. An adjusted score may be computed for the API endpoint based on the distance score and the similarity scores. The API endpoint may be registered based on the adjusted score being below a permissions threshold.Type: ApplicationFiled: December 13, 2023Publication date: June 6, 2024Applicant: Capital One Services, LLCInventors: Christian CARROLL, Madhav AYYAGARI, Terrence MOWER, Amit PANDEY

Patent number: 11781522Abstract: A rotor blade assembly of a wind turbine includes a rotor blade having an aerodynamic body with an inboard region and an outboard region. The inboard and outboard regions define a pressure side, a suction side, a leading edge, and a trailing edge. The inboard region includes a blade root, whereas the outboard region includes a blade tip. The rotor blade also defines a chord and a span. Further, the inboard region includes a transitional region of the rotor blade that includes a maximum chord. Moreover, a unitless first derivative of the chord with respect to the span of the rotor blade in the transitional region ranges from about ?0.10 to about 0.10 from the maximum chord over about 15% of the span of the rotor blade. In addition, the unitless first derivative of the chord with respect to the span a slope of a change in the chord in is greater than about ?0.03 at an inflection point of the chord in the outboard region.Type: GrantFiled: August 17, 2021Date of Patent: October 10, 2023Assignee: General Electric CompanyInventors: Christian Carroll, Murray Fisher, Benoit Philippe Petitjean, Andreas Herrig, Drew Adam Wetzel, Jonathon Paul Baker

Publication number: 20230031691Abstract: Methods and systems are disclosed herein for weighting training data for training a machine learning model. A computing system may use performance metrics to weight some training data over other training data. Weighting training data may increase the ability of a machine learning model to train faster and/or train to generate improved output. A portion of the training data may be weighted according to how well a machine learning model performs after being trained on the portion of training data. The computing system may train machine learning models using different data to train each machine learning model. The computing system may compare one or more performance metrics of each machine learning model and assign a weight to each corresponding dataset based on the comparison. The computing system may use the weighted dataset to train a machine learning model.Type: ApplicationFiled: July 29, 2021Publication date: February 2, 2023Applicant: Capital One Services, LLCInventors: Christian CARROLL, Rachel ATMADJA, Osinaka DESMOND, Sze WONG
