概要
• Multilayer Network 上での 伝搬を考える
• 感染モデルである SIRモデル、およびそれの変化形
を主に扱う
SIRモデル[145,233]
• 感染モデルで最も一般的なもの
• 人が健康な状態から発症し、治癒する
一連の流れを表す
Susceptible Infected Recover
SIR のTWO LAYER での研究
• Wangら[346]
layer内の辺と間での辺とを比較
• Dickisonら[107]
2つのネットワークのつながりの強さを考慮
• Zhaoら[368]
感染を広げている存在の認識
など
SIRのMULTIPLEX NETWORKでの研究
• Minら[229]
SIRモデルを 2層Multiplex graphで研究した
• Shaiら[293]
2層のMultiplex Networksで検証
レイヤー間の相関が正であるほうがしきい値が低い
SIRのMULTIPLEX NETWORKでの研究
• Yaganら[365]
「物理層」がすべてのノードを含みそれ以外は
その部分集合
• Buonoら[70]
2層あるが共通ノードがほぼないネットワークでの実験
SIRのMULTIPLEX NETWORKでの研究
• Joら[174]
感染と情報の2層グラフ上のSIRモデルのvariantを定義
• FunkとJansen[125]
2層グラフ上でSIRモデルを使って
2つの感染症の相互作用を研究
SISモデル[289]
• 複数回感染するモデル
Susceptible – infected – Susceptible
これもまたMultiplexネットワークで研究されている
SISのMULTIPLEX NETWORKでの研究
• 2つの感染症によるシュミレーション
• Sanzら[287]
SISを拡張し 回復からの感染はノードの状態、
ほかの感染症にもよることにした
• Vidaら[342]
Multiplex network上のマルウェアに応用
SISのMULTIPLEX NETWORKでの研究
• Granellら[144]
社会での接触と情報拡散のふたつのlayer
• Sahnehら[283]
“alert”状態を定義 非感染者が情報を
発信している
• Limaら[206]
様々な感染拡大プロセスを研究
• Shaiら[294]
レイヤー間の感染も考える
その他の拡散モデル
• Gomezら[141]
node- alined multiplexネットワークで実験
コンビナトリアル 上ラプラシアン行列を利用する
• DeDomenicoら[102]
ランダムウォークをmultiplexネットワークで実験
この時間はレイヤーのトポロジー、レイヤー間の
つながりの強さに依存
その他
SI モデル ノードが治癒しないモデル[245]
• Javarone[170]
SIモデルのvariantを研究
レイヤーがメディアと社会ネットワーク
• Centolaなど[81]
情報の拡散と振る舞いの採択といった複雑伝染の応用
まとめ
• SIR モデルやSISモデルをMultilayer Networkに
適用した研究がある
• 病気の拡散以外にも応用可能
• その他これらを使っていない研究もある
MULTIPLEX のランダムウォーク
