In machine learning, cross-validation is a technique used to evaluate how well a model would generalise to an unknown dataset. To do this, the data must be divided into several subsets, or "folds." A subset of these subsets is used to train the model, and the remaining portion is used...

atomistic simulations of phosphorus have remained an outstanding challenge. Here, we show that a universally applicable force field for phosphorus can be created by machine learning (ML) from a suitably chosen ensemble of quantum-mechanical results. Our model is fitted to density-...
Below are the four types of integrity constraints in DBMS, each playing a unique role in ensuring your database remains well-structured and reliable. 1. Domain Constraint Domain constraints define the permissible set of values for a column, ensuring that data entered into the database is valid....

The system derives a decision tree from a set of learning data ( tags of which the purposes are known) and classifies tags in webpages under evaluation. Classification accuracy was evaluated by cross validation with 200 test data collected from the Web. Result of the evaluation revealed that 1...
