WebHashing keys in Data Vault allows integration keys to be loaded in a deterministic way from multiple sources in parallel. This also removes the need for key lookups between related entities. Hashing row checksums for identifying changes allows the load process to compare a single generated hash to identify if an attribute has changed for a key. WebAbstract. This paper proposes a fast and scalable method for uncertainty quantification of machine learning models' predictions. First, we show the principled way to measure the uncertainty of predictions for a classifier based on Nadaraya-Watson's nonparametric estimate of the conditional label distribution.
