Randomized reference models for temporal networks
Laetitia Gauvin, Mathieu Génois, Márton Karsai +4
Many dynamical systems can be successfully analyzed by representing them as networks. Empirically measured networks and dynamic processes that take place in these situations show h…
The structured backbone of temporal social ties
Teruyoshi Kobayashi, Taro Takaguchi, Alain Barrat
In many data sets, crucial information on the structure and temporality of a system coexists with noise and non-essential elements. In networked systems, for instance, some edges m…
A general formulation of long-range degree correlations in complex networks
Yuka Fujiki, Taro Takaguchi, Kousuke Yakubo
We provide a general framework for analyzing degree correlations between nodes separated by more than one step (i.e., beyond nearest neighbors) in complex networks. One probability…
Input-output relationship in social communications characterized by spike train analysis
Takaaki Aoki, Taro Takaguchi, Ryota Kobayashi +1
We study the dynamical properties of human communication through different channels, i.e., short messages, phone calls, and emails, adopting techniques from neuronal spike train an…
Coverage centralities for temporal networks
Taro Takaguchi, Yosuke Yano, Yuichi Yoshida
Structure of real networked systems, such as social relationship, can be modeled as temporal networks in which each edge appears only at the prescribed time. Understanding the stru…
Community detection in directed acyclic graphs
Leo Speidel, Taro Takaguchi, Naoki Masuda
Some temporal networks, most notably citation networks, are naturally represented as directed acyclic graphs (DAGs). To detect communities in DAGs, we propose a modularity for DAGs…
Existence of outsiders as a characteristic of online communication networks
Taro Takaguchi, Takanori Maehara, Masashi Toyoda +1
Online social networking services (SNSs) involve communication activities between large number of individuals over the public Internet and their crawled records are often regarded…
Sufficient conditions of endemic threshold on metapopulation networks
Taro Takaguchi, Renaud Lambiotte
In this paper, we focus on susceptible-infected-susceptible dynamics on metapopulation networks, where nodes represent subpopulations, and where agents diffuse and interact. Recent…
Suppressing epidemics on networks by exploiting observer nodes
Taro Takaguchi, Takehisa Hasegawa, Yuichi Yoshida
To control infection spreading on networks, we investigate the effect of observer nodes that recognize infection in a neighboring node and make the rest of the neighbor nodes immun…
Observability transitions in correlated networks
Takehisa Hasegawa, Taro Takaguchi, Naoki Masuda
Yang, Wang, and Motter [Phys. Rev. Lett. 109, 258701 (2012)] analyzed a model for network observability transitions in which a sensor placed on a node makes the node and the adjace…
Bursty communication patterns facilitate spreading in a threshold-based epidemic dynamics
Taro Takaguchi, Naoki Masuda, Petter Holme
Records of social interactions provide us with new sources of data for understanding how interaction patterns affect collective dynamics. Such human activity patterns are often bur…
Self-exciting point process modeling of conversation event sequences
Naoki Masuda, Taro Takaguchi, Nobuo Sato +1
Self-exciting processes of Hawkes type have been used to model various phenomena including earthquakes, neural activities, and views of online videos. Studies of temporal networks…
Importance of individual events in temporal networks
Taro Takaguchi, Nobuo Sato, Kazuo Yano +1
Records of time-stamped social interactions between pairs of individuals (e.g., face-to-face conversations, e-mail exchanges, and phone calls) constitute a so-called temporal netwo…
Predictability of conversation partners
Taro Takaguchi, Mitsuhiro Nakamura, Nobuo Sato +2
Recent developments in sensing technologies have enabled us to examine the nature of human social behavior in greater detail. By applying an information theoretic method to the spa…
Voter model with non-Poissonian interevent intervals
Taro Takaguchi, Naoki Masuda
Recent analysis of social communications among humans has revealed that the interval between interactions for a pair of individuals and for an individual often follows a long-tail…
