Abstract: Systems, apparatuses, and methods for training and/or assessing the stability of a machine learning (ML) model. Training and/or assessing the stability may include, for each input sample n of N input samples, for each perturbation q of Q perturbations: determining a perturbed input sample nq by perturbing the input sample n and using the ML model to obtain a perturbed output yqn based on the perturbed input sample nq. Training and/or assessing the stability may include, for each input sample n of the N input samples, aggregating the perturbed outputs yqn to obtain an aggregate perturbed output yn of the Q perturbations for the input sample n. Training the ML model may include updating one or more parameters of the ML model based on at least the aggregate perturbed outputs yn. Assessing the stability may include aggregating the aggregate perturbed outputs yn (or relative output variations ynrel).

Abstract: Systems, apparatuses, and methods for training a machine learning (ML) model. Training the ML model may include using contour lines on a plot of prediction values to expected values to determine loss values indicative of errors between prediction values output by the ML model and corresponding expected values. The contour lines may be associated with loss values. Using the contour lines to determine the loss values may include, for each prediction value-expected value pair: generating a one-dimensional loss function through the prediction value-expected value pair, and using the one-dimensional loss function to determine a loss value for the prediction value-expected value pair. Training the ML model may include using an overall loss function to determine an overall loss of the ML model based on the determined loss values. Training the ML model may include adjusting the ML model to minimize the overall loss of the ML model.

Abstract: Solutions for enforcing both syntactic and semantic correctness of domain-specific data queries include: receiving a data query; constraining an operation of the data query to enforce semantic correctness, wherein enforcing semantic correctness comprises: determining semantic information associated with each of a plurality of data entities; based on at least the semantic information, determining whether combining the two data entities of the plurality of data entities is allowed or is not allowed; based on at least determining that combining the two data entities is allowed, permitting combining the two data entities in the data query; and based on at least determining that combining the two data entities is not allowed, preventing combining the two data entities in the data query; and executing the data query. Some examples further include basing the permission on (at least) an ontology between the semantic information of the two data entities and a set of axioms.

Abstract: An apparatus and method for depositing an aerosol that has an ultrafast pneumatic, shutter. The flow of aerosol through the entire deposition flow path is surrounded by at least one sheath gas, thereby greatly increasing reliability. The distance between the aerosol switching chamber and a reverse gas flow chamber input is minimized to reduce switching time. The distance from the switching chamber to the nozzle exit is also minimized to reduce switching time. The gas flows in the system are configured to maintain a substantially constant pressure in the system, and consequently substantially constant flow rates through the deposition nozzle and exhaust nozzle, to minimize on/off switching times. This enables the system to have a switching time of less than 10 ms.
