多重情緒下虛擬代理人之決策機制

混合情緒，特別是互相衝突的矛盾心情，常常影響人類或是虛擬代理人的決策行為。當矛盾情緒產生時，原本要執行的計畫或是方案常經過妥協以後再執行。此篇論文首先討論何為矛盾情緒再定義，之後延伸並修改心理學的情緒產生結構OCC model讓代理人能對更多種環境反應出擬人的情緒。在代理人的部分，我們提出一個以網路架構為主並仿生的模型來產生情緒，此模型特別強調可同時產生多種情緒，企圖模擬人類複雜的心境。當矛盾發生時，本論文也提出相對應的演算法，讓代理人能夠用一定的決策流程去解決其矛盾，並找出一妥協的方案。此論文並提供了一個情境去模擬代理人的決策思考行為。實驗部分，我們提出一份類似前述情境的問卷，測試解決矛盾的演算法之正確性。最後我們將探討實驗結果以及討論矛盾情緒應用在虛擬代理人上的結論。

Mixed emotions, especially those in conflict, sway agent decisions and result in dramatic changes in social scenarios. However, the emotion models and architectures for virtual agents are not yet advanced enough to be imbedded with coexisting emotions. In this thesis, an improved emotion model from OCC integrated with decision making algorithms is proposed to deal with two topics: the generation of coexisting emotions, and the resolution to ambivalence, in which two emotions conflict. A scenario of ambivalence is provided to illustrate the process of agent’s decision-making.
