Abstract: The present application relates to a method (I) for preparing a brivaracetam intermediate, comprising the steps of dissolving the compound represented by B-P and 1S,2S-diphenylethylenediamine in a solvent for resolution, crystallizing, filtering, and recrystallizing to obtain the compound represented by B-Q, which is then converted to the brivaracetam intermediate represented by B-R. This method can effectively resolve the compound represented by B-P. The present application also provides a method for preparing brivaracetam using the compound represented by B-R. The method can separate the effective components only through simple steps such as extraction, washing, drying, and concentration without requiring use of chiral chromatography column to separate isomers in the preparation process, and thus the separation process is simple, greatly reducing the production cost of brivaracetam.

Abstract: Systems, methods, and computer program products are directed to machine learning techniques that use a separate embedding layer. This can allow for continuous monitoring of a processing system based on events that are continuously generated. Various events may have corresponding feature data associated with at least one action relating to a processing system. Embedding vectors that correspond to the features are retrieved from an embedding layer that is hosted on a separate physical device or a separate computer system from a computer that hosts the machine learning system. The embedding vectors are processed though the machine learning model, which may then make a determination (e.g. whether or not a particular user action should be allowed). Generic embedding vectors additionally enable the use of a single remote embedding layer for multiple different machine learning models, such as event driven data models.

Abstract: This application discusses identifying data processing timeouts in live risk analysis systems. A service provider, such as an electronic transaction processor, may provide a production computing environment that includes a risk analysis system having one or more risk models, which may be machine-learning based. These risk models may be utilized in order to determine whether incoming data processing requests are fraudulent. To test these risk models using production data traffic, an audit computing environment made of a set of machines that do not service production computing environment requests, but that utilize databases and data connections as are used by the production systems. The audit computing environment may thus mirror the risk models and functionality of the production computing environment without the drawbacks of a typical fully separate testing environment.
