Abstract: Conventional approaches are not efficient for the screening of active multi component alloy catalysts. Present disclosure provides systems and method that incorporate elements of materials chemistry, artificial intelligence (AI)/machine learning (ML) and optimization for the screening of such active catalysts for a target chemical reaction. Given a set of elements constituting the alloy and the target reaction, surface atomic structures of several different alloy composition and configurations are constructed. Then, adsorption energy of key reaction intermediates on the surface atomic structures are computed using quantum chemical methods (QCM). Next, an AI/ML model is trained using data obtained from QCM to predict the adsorption energy of the reaction intermediates on the alloy surface. Finally, numerical optimization is used to identify alloy compositions that maximize the activity and selectivity of the catalyst for a target chemical reaction.

Abstract: Embodiments relate to enhancing data labeling for machine learning model training using context data. The context data is provided to data labelers to improve accuracy of labels assigned by the data labelers, such as those assigned for ambiguous or unclear target objects. In an example, a system determines and provides context sets for target objects at user devices. The system generates a first training dataset and a second training dataset with labels obtained in connection with a first subset and a second subset of the context sets, respectively. The system trains a first and second instance of a machine learning model on the first training dataset and the second training dataset, respectively, and determines a respective accuracy score for the model instances. If the first instance is more accurate than the second instance, the system generates subsequent context sets based on characteristics of the first subset of context sets.
