Classification Error
Classification error, the discrepancy between predicted and true class labels, is a central challenge in machine learning, driving research aimed at improving model accuracy and understanding error sources. Current research focuses on developing novel loss functions tailored to specific problem structures (e.g., multi-objective optimization, long-tailed distributions), analyzing error probabilities using large deviations theory and other statistical methods, and exploring techniques like metric learning and label correction to mitigate errors. These advancements are crucial for improving the reliability and trustworthiness of machine learning systems across diverse applications, from medical diagnosis to autonomous driving, where accurate classification is paramount.
