DIVISION DEVICE, INFERENCE DEVICE, INFERENCE METHOD, DIVISION PROGRAM, AND INFERENCE PROGRAM

To prevent a risk of leakage of training data without requiring a particular execution environment.SOLUTION: A division device includes: a division unit which divides an inference model to produce a plurality of divided inference models; and a transmission unit which transmits a particular divided inference model including an input layer of the inference model, of the plurality of divided inference models produced by the division unit, to a particular inference device of a plurality of inference devices and transmits the other divided inference model(s) except for the particular divided inference model, of the plurality of divided inference models, to the other inference device(s) except for the particular inference device, of the plurality of inference devices.SELECTED DRAWING: Figure 2 【課題】特定の実行環境を必要とせず、訓練データの漏洩リスクを抑制すること。【解決手段】分割装置は、推論モデルを分割して、複数の分割推論モデルを生成する分割部と、前記分割部によって生成された複数の分割推論モデルのうち前記推論モデルの入力層を含む特定の分割推論モデルを、複数の推論装置のうち特定の推論装置に送信し、前記複数の分割推論モデルのうち前記特定の分割推論モデル以外の他の分割推論モデルを、前記複数の推論装置のうち前記特定の推論装置以外の他の推論装置に送信する送信部と、を有する。【選択図】図２
