【Abstract】 The Tri-training algorithm is a type of semi-supervised learning algorithm in machine learning algorithms. Since its proposal,improvements and variants based on Tri-training have become increasingly diverse. This paper introduces the principles and procedural steps of the Tri-training algorithm,and based on this,analyzes its application status in the field of medical auxiliary diagnosis. An outlook on the future development directions of the improved Tri-training algorithm in the medical field is presented.更多还原
