The method includes representing the feature vectors and relations as a first graphical representation. The method also includes mapping said first graphical representation into a second graphical representation wherein the mapping comprises using an attention mechanism, said attention mechanism establishes the importance of specific feature vectors dependent on their neighbourhood and the relations between the feature vectors, said mapping transforming the feature vectors of the first graphical representation to transformed feature vectors in the second graphical representation. The method also includes combining the transformed feature vectors to obtain a third combined representation said third combined representation being an indication of the classification of the graphical structure.

Abstract: Embodiments described herein allow predictions to be made for any continuous position by making use of a continuous position embedding based on previous observations. An encoder-decoder structure is described herein that allows effective predictions for any position without requiring predictions for intervening positions to be determined. This provides improvements in computational efficiency. Specific embodiments can be applied to predicting the number of events that are expected to occur at or by a given time. Embodiments can be adapted to make predict based on electronic health records, for instance, determining the likelihood of a particular health event occurring by a particular time.

Abstract: A computer-implemented method includes a computing system having a database that stores multiple datasets and that accesses the database to perform operations on a first dataset to produce multiple second datasets. The system determines a relationship between the first dataset and each second dataset of the multiple second datasets. The system also determines a relationship between respective groups of the first dataset and determines a relationship between respective groups of each second dataset. The system generates summary objects based, in part, on the determined relationships between respective groups of the first and second datasets. The system includes a machine learning system that uses the respective summary objects to analyze the performed operations that produced the multiple second datasets. Based on the analyzed performed operations, the machine learning system generates a data analysis model that indicates sequences of operations for achieving particular desired data analysis outcomes.
