With the continuous development of big data and IoT (Internet of Things), dynamic online computation has become a common computing pattern; however the field of dynamic online computation faces challenges in deducing and solving uncertainty problems. A three-way decision theory with probabilistic rough set method is an efficient tool for mining uncertain knowledge; thus a dynamic online computing approach of three-way decision theory with probabilistic rough set is proposed in this paper, in accordance with the features of data dynamic synchronization. First, a data model is established to describe the inherent features of dynamic online computation via memory sliding window mode. In terms of the variational features of dynamic online computation of the above model, a three-way decision conditional probability and the change rule of three-way area are deduced as diverse variational patterns of data. Finally, a novel algorithm of online rapid computation is proposed. The obtained three-way decision rule is identical with the three-way decision algorithm of classic probability. By comparison with the classic three-way decision algorithm through multiple experiments, the proposed online rapid computation algorithm is confirmed to have high efficiency and stability.
