Fig. 3From: Machine learning application for classification of Alzheimer's disease stages using 18F-flortaucipir positron emission tomographyHyper-parameter optimization for machine learning model framework using Optuna. The Optuna, as a method library for hyper-parameter tuning, can be used to derive the most optimized model performance. The higher density of presented lines refers to a combination of parameters that can create high performanceBack to article page
