Prediction device, learning device, and learning method

A prediction device is provided with: an input unit; a processing unit that extracts an index score based on the first index and the second index, and an index score to be input to a compatibility prediction model of the food material and the seasoning; and an output unit that outputs, as a predicted value for the compatibility between the food material and the seasoning, a compatibility score output from the compatibility prediction model by inputting the index score extracted by the processing unit. 预测装置具备：输入部；处理部，提取基于第一指标和第二指标的指标得分和用于输入至食材与调料的相容性预测模型的指标得分；以及输出部，将通过输入由处理部提取的指标得分而从相容性预测模型输出的相容性得分作为食材与调料的相容性预测值进行输出。
