It effectively detects and fixes inconsistencies in real-life data based on conditional dependencies, an extension of database dependencies by enforcing bindings of semantically related data values. It accurately identifies records fro...

Taguchi methods provide a comprehensive methodology for quality improvement. The objective is based on a robust design and involves conducting experiments using orthogonal arrays and the estimation factor levels combination that optimizes a given performance measure, typically a Signal-to-Noise ratio. The problem is more complex in the case of multiple responses since the combinations of factor...
