It is interesting to find the clustering with potential value in financial time series. In this paper, we focus on this topic. The owned features of the clusters with potential value are provided firstly. Then, the agglomerative hierarchical clustering (AHC) is used to find those clusters automatically. There are two innovations in this paper. The first one is that the features of the clusters with...
Traditional viral marketing problems aim at selecting a subset of seed users for one single product to maximize its awareness in social networks. However, in real scenarios, multiple products can be promoted in social networks at the same time.
