Title:
環境因子予測装置、方法、プログラム、学習済モデルおよび記憶媒体
Document Type and Number:
Japanese Patent JP7109123
Kind Code:
B2
Abstract:
Provided is an environmental factor prediction device that includes a predictor and predicting means. The predictor uses, as explanatory variables: water quality data in a plurality of layers in water, the data including a value corresponding to a biochrome level or a bioluminescence level (e.g. chlorophyll concentration), water temperature, salt concentration, dissolved oxygen, turbidity and flow rate; and meteorological data including atmospheric temperature, precipitation and sunshine duration, and outputs an estimated value of each item of the explanatory variables at a unit time later, based on time series data of the explanatory variables. The predicting means predicts the water quality data up to an N unit time later by repeating prediction using the estimated value acquired by the predictor as input of the predictor again. According to the present invention, the environmental factors that cause generation of red tide, blue tide or water bloom, diseases of fish, and the like, can be predicted, on a long term basis and at high accuracy.
