Patent number: 11921815Abstract: A server system can receive an input identifying a problem to generate a solution using a machine-learning application. The method selects a machine-learning model template from a plurality of templates based at least in part on the input. The method analyzes one or more formats of the customer data to generate a customer data schema based at least in part a data ontology that applies to the identified problem. The method determines whether the customer data schema is misaligned with one or more key features of the selected machine-learning model template. Based on this determination, the method analyzes the metadata for the selected machine-learning model template to determine what additional information is required to re-align the customer data with the data expectations. The method can include gathering the addition information required to re-align the customer data with the data expectations of the selected machine-learning model template.Type: GrantFiled: September 13, 2020Date of Patent: March 5, 2024Assignee: Oracle International CorporationInventors: Alberto Polleri, Sergio Aldea Lopez, Marc Michiel Bron, Dan David Golding, Alexander Ioannides, Maria del Rosario Mestre, Hugo Alexandre Pereira Monteiro, Oleg Gennadievich Shevelev, Larissa Cristina Dos Santos Romualdo Suzuki, Xiaoxue Zhao, Matthew Charles Rowe

Publication number: 20240070494Abstract: The present disclosure relates to systems and methods for an intelligent assistant (e.g., a chatbot) that can be used to enable a user to generate a machine learning system. Techniques can be used to automatically generate a machine learning system to assist a user. In some cases, the user may not be a software developer and may have little or no experience in either machine learning techniques or software programming. In some embodiments, a user can interact with an intelligent assistant. The interaction can be aural, textual, or through a graphical user interface. The chatbot can translate natural language inputs into a structural representation of a machine learning solution using an ontology. In this way, a user can work with artificial intelligence without being a data scientist to develop, train, refine, and compile machine learning models as stand-alone executable code.Type: ApplicationFiled: November 3, 2023Publication date: February 29, 2024Applicant: Oracle International CorporationInventors: Alberto Polleri, Sergio Lopez, Marc Michiel Bron, Dan David Golding, Alexander Ioannides, Maria del Rosario Mestre, Hugo Alexandre Pereira Monteiro, Oleg Gennadievich Shevelev, Larissa Cristina Dos Santos Romualdo Suzuki, Xiaoxue Zhao, Matthew Charles Rowe
