Abstract
(EN)
This spectrum analysis device 1 is a device for analyzing an object under analysis including one or more standard substances from among a plurality of standard substances on the basis of a light spectrum produced by the object under analysis. The spectrum analysis device 1 comprises a processing unit 10, input unit 20, learning unit 30, and analysis unit 40. The processing unit 10 has a recurrent neural network (RNN). The input unit 20 inputs data for the light spectrum produced by the standard substance or object under analysis into each cell of the RNN one item of data at a time. As a result, a device and method are achieved that are capable of highly efficient and highly accurate spectrum analysis.

L'invention concerne un dispositif d'analyse de spectre (1) constituant un dispositif permettant d'analyser un objet en cours d'analyse comprenant une ou plusieurs substances standard parmi une pluralité de substances standard en fonction d'un spectre de lumière produit par l'objet en cours d'analyse. Le dispositif d'analyse de spectre (1) comprend une unité de traitement (10), une unité d'entrée (20), une unité d'apprentissage (30) et une unité d'analyse (40). L'unité de traitement (10) comprend un réseau neuronal récurrent (RNN). L'unité d'entrée (20) entre des données pour le spectre lumineux produit par la substance standard ou l'objet en cours d'analyse dans chaque cellule du RNN, élément de données par élément de données. Ainsi, un dispositif et un procédé sont obtenus et permettent de réaliser une analyse de spectre hautement efficace et hautement précise.
