AI generates synthetic spectra to boost glioma classification accuracy

Researchers have developed a conditional variational autoencoder ($eta$-CVAE) to generate synthetic Raman spectra for improving glioma classification in machine learning. While models trained solely on synthetic data underperformed those trained on real spectra, augmenting real data with synthetic spectra consistently enhanced classification accuracy. This suggests that generative models can offer valuable regularization for classifiers, even when dealing with small and imbalanced biomedical datasets. AI
