Abstract: A data classification system obtains a data set including first data associated with a first characteristic and second data associated with a second characteristic. In response to obtaining the data set, the system uses a classification model to generate a classification by classifying the first data into majority data and the second data into minority data. From the classification and using the classification model, the system determines a loss. The system modifies the classification model based on this loss to generate an updated classification model. The system uses the updated classification model to re-classify a subset of the first data into the minority data and a subset of the second data into the majority data.

Abstract: A transaction classification system obtains a data set including first data associated with a first characteristic and second data associated with a second characteristic. In response to obtaining the data set, the system uses a classification model to generate a classification by classifying the first data into majority data and the second data into minority data. From the classification and using the classification model, the system determines a cost. The system modifies the classification model based on this cost to generate an updated classification model. The system uses the updated classification model to re-classify a subset of the first data into the minority data and a subset of the second data into the majority data.

Abstract: A pressure indicator for a respiratory treatment device, the pressure indicator including an instrument for measuring pressures, a conduit configured to transmit a pressure within the respiratory treatment device to the instrument, and a pressure stabilizer orifice positioned within the conduit.

Abstract: An oscillating positive expiratory pressure device comprising a housing enclosing at least one chamber, a chamber inlet configured to receive exhaled air into the at least one chamber, and a chamber outlet configured to permit exhaled air to exit the at least one chamber. A channel is positioned in an exhalation flow path between the chamber inlet and the chamber outlet, with the channel being movably connected to a chamber of the at least one chamber. An air flow regulator is movable with respect to the channel between a first position, where the flow of air through the channel is restricted and a second position, where the flow of air through the channel is less restricted, the air flow regulator being configured to repeatedly move between the first position and the second position in response to a flow of exhaled air.

Abstract: A system for query optimization by a federation engine is provided. When a data source supports a target feature of an expression of a query in the common query language, the system executes a converter for the data source to convert the target feature to the corresponding feature of the data source query language. The system then submits to the data source a query with the expression with the converted target feature so that the expression is evaluated at the data source and receives query results. When a data source does not support the target feature of the expression, the system submits to the data source a query without the expression and evaluates the expression on the query results returned by the data source. The system then combines the query results based on the evaluation of the expression as the query results of the query.
