To appropriately determine an update necessity of a machine learning model according to a situation change within an area that the machine learning model is responsible for.SOLUTION: A model update necessity determining system that determines an update necessity of a machine learning model which predicts a behavior change of a target vehicle based on target vehicle data obtained from the target vehicle within a predefined area where learning is performed by using data from a vehicle under predetermined learning condition, and comprises: a deviation number calculation unit that calculates the number of deviations by which the target vehicle data deviates from the learning conditions based on the target vehicle data of the target vehicle within the area; and an update necessity determining unit that determines an update necessity for the machine learning model based on the deviation number.SELECTED DRAWING: Figure 4

    【課題】機械学習モデルの担当するエリア内の状況変化に応じて機械学習モデルの更新の要否を適切に判定する。【解決手段】所定の学習条件の車両のデータを用いて学習が行われ、予め設定されたエリア内の対象車両から取得した対象車両データに基づいて対象車両の挙動変化を予測する機械学習モデルの更新の要否を判定するモデル更新要否判定システムであって、エリア内の対象車両の対象車両データに基づいて、対象車両データが学習条件から逸脱した逸脱数を算出する逸脱数算出部と、逸脱数に基づいて、機械学習モデルの更新の要否を判定する更新要否判定部と、を備える。【選択図】図4
