Abstract: Techniques are described herein that are capable of detecting an algorithmic attack against a hosted artificial intelligence (AI) system based on inputs (e.g., queries) and outputs of the hosted AI system. In a first example, a feature-based classifier model is used to generate a classification score based on features that are derived from numerical representations of the queries and the outputs, and an algorithmic attack is detected based on the classification score being greater than or equal to a score threshold. In a second example, a transformer-based model is used to generate a vector by providing a multivariate time series, which is based on attribute(s) of the inputs and attribute(s) of the outputs, as an input to the transformer-based model, and an algorithmic attack is detected based on a distance between the vector and a point corresponding to a reference vector being less than or equal to a distance threshold.

Abstract: A method to deposit a multi-layer stack for device applications includes implementing a model driven target selection for deposition. One or more targets may be procured with an initial stoichiometric composition or elemental purity. The targets may be utilized to form the multi-layer stack, and measurements may be made of chemical composition and electrical properties of the multi-layer stack. The measurements may be compared to reference target values and if measurement results are not within tolerance, the composition of the targets can be changed to yield a successive multi-layer stack. The process can be iterated until measurement results are within tolerance of target results. Additional experimentation with post deposition thermal anneal can be performed to optimize multi-layer stack properties.

Abstract: An equipment health model is generated for a piece of hydraulic equipment using operating characteristic(s) of the piece of hydraulic equipment and status of the piece of hydraulic equipment. The equipment health model uses fingerprints (initial signatures of the equipment) and key inputs (pressure, temperature, time durations, gallon counts to actuate, etc.) in the operating characteristic(s) of the piece of hydraulic equipment to determine health of the piece of hydraulic equipment. Specific patterns/trends in the operating characteristic(s) of the piece of hydraulic equipment are used as leading indicator to measure, alert, and alarm on the health of the piece of hydraulic equipment. The alerts are escalated to personnel to ensure the equipment health is proactively addressed.
