Description
ここで、上式(15)の目的関数を、時間別エリア人口データから各タイムステップにおけるエリア間の移動人数を推定する枠組みで説明すると、
・nijk:時刻iからi+1にかけて、エリアjからエリアkに移動した人の数(移動人数)
・φijk:時刻iからi+1にかけて、エリアjからエリアkへの移動のしやすさ(移動確率)
・nij:時刻iにおけるエリアjの(観測ノイズののっていない)真の人口
・yij:時刻iにおけるエリアjの観測された人口
となる。したがって、最適化問題(式(11))を解くことで、yij(エリアjの人口)及びφijk(エリアjからエリアkへの移動確率)から、nijk(エリアjからエリアkに移動した人数)及びnij(エリアjの真の人口)を推定することができる。
