Abstract: Disclosed is a method for processing Raman data of eosinophil based on artificial intelligence, the method being executed by a device, the method including generating Raman data by performing Raman analysis using a specific wavelength on eosinophils isolated from blood of a diagnosed person, pre-processing the generated Raman data, assigning a weight to the pre-processed Raman data for each of components including a nucleus, a cell membrane, a granule, and a background, classifying data for each component based on a result of assigning the weight, extracting data in which the component is the granule based on a classified result; and determining whether a specific disease has occurred in the diagnosed person through eosinophil characteristics of the diagnosed person based on the extracted data.
