Data analysis and call prediction on dyadic data from an understudied population

Text and phone calls: user behaviour and dual-channel communication prediction

“…This section discusses the proposed algorithm for the dual-channel prediction that is a generalized version of an algorithm for single-channel prediction by Nasim et. al [11]. The previous study showed that calls between an ego-alter pair contain patterns induced by sociological constraints called socio-temporal patterns.…”

“…In contrast, small data is often structured, easy to access, and easy to manage. Hence, small data has been successfully used to solve problems surrounding individuals like impact of communication technologies on relationships [24,25], communication behaviour of smartphone users [10,[13][14][15], user-centric context aware models for prediction [26], and call prediction [2,11].…”

“…Studies investigated the existence of temporal patterns in human communication behaviour [11] and showed that each individual has a unique and persistent communication pattern that follows daily rhythms [27][28][29]. Furthermore, these social signatures are present in both calls [9,11] and text messages [10]. It also seems that these signatures persist over time, despite the major changes in the ego's social network due to relocation, etc.…”

“…One of the more established algorithms is proposed by Stefanis et al [2,17] which uses recency and frequency of communication as contextual information and achieved a prediction accuracy of 80%. In another recent study, Nasim et al [11] proposed a machine learning-based algorithm for predicting the next call at a particular time. They achieved an accuracy of 78% for a list of size 5 on the Reality Mining dataset [39].…”

“…Motivated by these findings, it was conjectured that similar socio-temporal patterns can also be found in the dual-channel communication environment. However, it was noted that there can be other alternatives to the planar models besides the one proposed in [11]. The three planar modelling techniques for dual-channel communication are described below.…”
