WebJun 30, 1994 · The aim of this paper is to carry out a comparative analysis on the descriptive and forecasting accuracy of the Box-Jenkins and diffusion models, on the basis of many different time series. The numerical procedures used in parameter calibration and the performance indexes employed in comparing the models' performance are explicitated. WebThis chapter presents the methodology used to develop the decision-making model. Also, the fuzzy dynamic TOPSIS method is summarized. A fuzzy multi-criteria decision-making problem is usually represented in the following matrix form: (1) where is the set of alternatives and is the set of criteria.
WebTools. In machine learning, diffusion models, also known as diffusion probabilistic models, are a class of latent variable models. They are Markov chains trained using variational inference. [1] The goal of diffusion models is to learn the latent structure of a dataset by modeling the way in which data points diffuse through the latent space.
