Liver steatosis, or fatty liver disease, is an increasingly prevalent global health issue that can lead to severe complications like cirrhosis and carcinoma. While liver biopsy is the diagnostic "gold standard," it is invasive, time-consuming, and carries risks. Standard non-invasive methods like BIA often face limitations in accuracy due to physiological variability, low data variability, and the "curse of dimensionality" when handling high-dimensional spectral data.
