The design of an embodied conversational agent that promotes physical activity to young Chinese adults living in the United States is described, along with specific cultural adaptations performed to tailor the agent to Chinese culture. Results of a pilot study comparing the Chinese exercise coach agent to another adapted to American culture demonstrated that participants found the Chinese agent more...
Dempster-Shafer evidence theory (DST) is a theoretical framework for uncertainty modeling and reasoning. The determination of basic belief assignment (BBA) is crucial in DST, however, there is no general theoretical method for BBA determination. In this paper, a method of generating BBA using fuzzy numbers is proposed. First, the training data are modeled as fuzzy numbers. Then, the dissimilarities...
Image segmentation is a classical problem in computer vision and has been widely used in many fields. Due to the uncertainty in images, it is difficult to obtain a precise segmentation result. To deal with the problem of uncertainty encountered in the image segmentation, an evidential Markov random field (EMRF) model is designed, based on which a novel image segmentation algorithm is proposed in this...
The aim of this paper is to solve resource-constrained projects scheduling problems (RCPSP) with complex hierarchical organization structure. A bi-level MODM model with fuzzy random coefficients is developed for RCPSP under hybrid uncertainty environment. In this model, construction contractor is considered as the upper level decision maker (ULDM) and outsourcing partner is the lower level decision...
In current market competition companies face with short product life cycle, high demand uncertainty and drastic declines of product values. This study analyses the price protection policy in channel coordination and proposes a two-period dynamic model of optimal price protection rate based on the single ordering. The result shows that, through setting reasonable the wholesale price and the price protection...
