讲座内容
Prediction models and their efficient evaluation arise as an important and timely direction of fundamental and applied research. However, there are no ideal models. It is impossible to envision a situation where any model can deliver an ideal fit to experimental data and needless to say that the quality of any model is of paramount importance to any application. To offer a sound and realistic evaluation of the quality of constructed models, it is legitimate and intuitively appealing to admit that the prediction results come in a certain non-numeric way.
The talk focus on the concepts of predictive models with prediction results being realized in the form of information granules. It introduces a comprehensive algorithmic setting as well as a detailed quantification of quality of information granules. Besides, some well-known constructs of statistically-guided prediction in linear regression are briefly reviewed. The generic idea of prediction intervals is generalized to embrace information granules of prediction including constructs. The talk also introduces a concept of a granular parameter space and a granular output space yielding a granular nature of prediction.
