To provide a lost track data estimation system of a marine vessel using machine learning.SOLUTION: A lost track data estimation system of a marine vessel using machine learning is constituted by comprising: an AIS track database which records track data of the marine vessel received via an AIS and includes a specification of the marine vessel; a marine vessel type classification part which segments a type of the marine vessel by length, width and draft of the marine vessel from the specification of the marine vessel; a marine vessel motion characteristic learning part which learns motion characteristics of the marine vessel according to the track data stored in the AIS track database and the type of the marine vessel classified by the marine vessel type classification part; an input part which receives input of information to an estimation object section from an operator; and a marine vessel track data estimation part which determines the optimal track by generating a track candidate set to the estimation object section, and generating time series prediction track data to calculate an error by comparison between the track candidate set and the time series prediction track data when the estimation object section of the marine vessel is selected.SELECTED DRAWING: Figure 1

    【課題】機械学習を用いた船舶の損失航跡データ推定システムを提供する。【解決手段】本発明の機械学習を用いた船舶の損失航跡データ推定システムは、AISを介して受信した当該船舶の航跡データを記録し、船舶の諸元を含むAIS航跡データベースと、船舶の諸元から船舶の長さ、幅および喫水によって船舶の種類を区分する船舶種類分類部と、AIS航跡データベースに格納された航跡データと船舶種類分類部によって分類された船舶の種類に応じて船舶の運動特性を学習する船舶運動特性学習部と、運用者から推定対象区間に対する情報の入力を受ける入力部と、船舶の当該推定対象区間が選択されると、推定対象区間に対する航跡候補集合を生成し、時系列予測航跡データを生成して航跡候補集合と時系列予測航跡データとの比較によって誤差を計算することにより最適航跡を決定する船舶航跡データ推定部とを含んで構成される。【選択図】図1
