Evaluating Reasoning Systems
ISBN: 9781494253462 / Angielski / Miękka / 102 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A review of the literature on evaluating reasoning systems reveals that it is a very broad area with wide variation in depth and breadth of research on metrics and tests. Consolidation is hampered by nonstandard terminology, differing methodologies, scattered application domains, unpublished algorithmic details, and the effects of domain content and context on the choice of metric and tests. The field of information metrology, which applies to reasoning as a kind of information processing, is still emerging from ad hoc experience in evaluating narrow kinds of information systems. This report...

ISBN: 9781494482893 / Angielski / Miękka / 198 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Abstract This supplement to the CFAST Technical Reference Guide provides details of the software development process for CFAST and accompanying validation for the model. It is based in part on the Standard Guide for Evaluating the Predictive Capability of Deterministic Fire Models, ASTM E 1355. The model evaluation process consists of two main components: verification and validation. Verification is a process to check the correctness of the solution of the governing equations. Verification does not imply that the governing equations are appropriate; only that the equations are being solved...
