| Outline of Final Research Achievements |
We have constructed a technique that judge the differentiation of cells and cell types noninvasively without using fluorescent molecules etc. by using depth learning. The date when differentiation of C2C12 (myoblast) starts is defined as Day 0. The phase contrast microscopy image data of Day 0, Day 3, Day 6 was classified with CNN (Convolutional Neural Network), and the accuracy of 91.8% was achieved. In addition, DNN (Deep Neural Network) succeeded in classifying Raman spectral data derived from three kinds of biological tissues with an accuracy of 86.2%. Furthermore, by using anti-Stokes Raman scattering (CARS), data acquisition time was greatly improved.
