Aortic regurgitation can eventually lead to heart failure. Mitral regurgitation may also require a valve replacement. In this condition, the mitral valve allows oxygenated blood to flow backwards into the lungs instead of continuing through the heart as it should. People with this condition may experience shortness of breath, irregular heartbeats and chest pain.
A training program is composed of a schedule of activi-. ties with training goals, learning objectives, subject areas, methods, trainers, trainees, methods of assessment, and. locations. A good training program is designed to address. performance problems, such as long delays in getting medi-. cines from suppliers to the main stores, delays in distribut-. ing medicines from midlevel stores to end-user units, or. Performance.
Validation Set. Once a model is built using the Training Set, the performance of the model must be validated using new data. If the Training Set itself was utilized to compute the accuracy of the model fit, the result would be an overly optimistic estimate of the accuracy of the model. This is because the training or model fitting process ensures that the accuracy of the model for the training data is as high as possible, and the model is specifically suited to the training data.
