Learning the Consistent Behavior of Common Users for Target Node Prediction across Social Networks: Supplementary Materials

چکیده
The objective function of CICF, with the non-negative constraints on V and E, is a special case of Non-negative Matrix Factorization (NMF) (Lee & Seung, 1999; Recht et al., 2012; Seung & Lee, 2001; Yang et al., 2012), and can be solved by a multiplicative update approach (Seung & Lee, 2001; Yang & Oja, 2010). However, this approach suffers from the fluctuation problem in convergence (Yang & Oja, 2011; Zhang et al., 2012), as shown in Fig. 1.

Learning the Consistent Behavior of Common Users for Target Node Prediction across Social Networks
We study the target node prediction problem: given two social networks, identify those nodes/users from one network (called the source network) who are likely to join another (called the target network, with nodes called target nodes). Although this problem can be solved using existing techniques in the field of cross domain classification, we observe that in many realworld situations the cross...
متن کاملUsing an Evaluator Fixed Structure Learning Automata in Sampling of Social Networks
Social networks are streaming, diverse and include a wide range of edges so that continuously evolves over time and formed by the activities among users (such as tweets, emails, etc.), where each activity among its users, adds an edge to the network graph. Despite their popularities, the dynamicity and large size of most social networks make it difficult or impossible to study the entire networ...

متن کاملA Link Prediction Method Based on Learning Automata in Social Networks
Nowadays, online social networks are considered as one of the most important emerging phenomena of human societies. In these networks, prediction of link by relying on the knowledge existing of the interaction between network actors provides an estimation of the probability of creation of a new relationship in future. A wide range of applications can be found for link prediction such as electro...
متن کاملLink Prediction across Heterogeneous Social Networks: A Survey
Online social networks have gained great success in recent years. Some online social networks only involving users and social links among users can be represented as homogeneous networks. Meanwhile, some other social networks containing abundant information, which include multiple kinds of nodes and complex relationships, can be denoted as heterogeneous networks. Predicting the missing links or...
