Abstract: Exemplary embodiments pertain to new techniques for classifying or labeling organized data. A major impediment to implementing high-quality machine learning is the lack of readily accessible labeled data. In some cases, data can be classified using a classifier, but these solutions can be inaccurate and slow. Exemplary embodiments address the problem of obtaining accurate labeled data in a timely manner by applying a classifier configured to operate on character-level embeddings. Among other advantages, this can help the classifier to recognize information contained within a data unit, such as a cell of a table. The classifier may operate within the organizational structure of the data, such as by operating across a particular row or column of a table. Because data within a particular row or column is often temporally organized (e.g., transactions that are logged in chronological order), row- or column-based approaches can yield more accurate results.

Abstract: A rotating equipment system with in-line drive-sense circuit (DSC) electric power signal processing includes rotating equipment, in-line drive-sense circuits (DSCs), and one or more processing modules. The in-line DSCs receive input electrical power signals and generate motor drive signals for the rotating equipment.

Abstract: The systems and methods described herein analyze one or more selected data sources in their entirety and determine data relationships, using a single-branch approach. Indexes are created based on the determined data relationships, and data from the one or more data sets is imported into the indexes and stored in a back-end storage system. Once the data is analyzed and stored in the indexes, a user can submit a request for a data visualization. In response to the request, the system automatically generates (e.g., builds) and displays the requested data visualization to the user. In some examples, the user may request a modification of the data visualization such as changing the timeframe shown in the data visualization or adding/removing data associated with a particular parameter, and the system will automatically generate the modified data visualization for the user.
