Abstract

This paper evaluates the performance of various supervised machine learning algorithms such as Logistic Regression, K-Nearest Neighbors (KNN), Extra Trees, LightGBM as well as a Multilayer Perceptron (MLP) neural network in the detection and diagnosis of liver disease. Existing methods for diagnosis tend to be highly invasive and time-consuming. A lack of qualified experts exacerbates these issues. Since blood tests, known as liver function tests, are a standard method to assess liver health, these models utilize blood enzyme levels like Bilirubin, Albumin, Alanine transaminase (SGPT), and Aspartate Aminotransferase (SGOT) to diagnose liver disease in patients. A total of 11 attributes are used to train the models. The algorithms are compared using metrics including, but not limited to, F1 score, accuracy, and precision. The Extra Trees classifier is shown to provide the highest accuracy of 0.89 as well as an F1 score of 0.88. Thus, it appears to be the best method for the timely and accurate diagnosis of liver disease using blood enzyme levels. In addition, the usage of machine learning algorithms alongside human medical expertise may help drastically reduce errors in clinical diagnosis. This paper establishes the feasibility of applying machine learning in various medical fields including the diagnosis of other diseases.
使用机器学习进行肝脏疾病诊断
本文评估了各种监督机器学习算法的性能,如Logistic回归、k -近邻(KNN)、Extra Trees、LightGBM以及多层感知器(MLP)神经网络在肝病检测和诊断中的应用。现有的诊断方法往往是高度侵入性和耗时的。缺乏合格的专家加剧了这些问题。由于血液检查,即肝功能检查,是评估肝脏健康的标准方法,这些模型利用胆红素、白蛋白、丙氨酸转氨酶(SGPT)和天冬氨酸转氨酶(SGOT)等血液酶水平来诊断患者的肝脏疾病。总共使用了11个属性来训练模型。使用指标对算法进行比较,包括但不限于F1分数、准确性和精度。Extra Trees分类器的最高准确率为0.89,F1分数为0.88。因此,利用血酶水平是及时准确诊断肝病的最佳方法。此外,机器学习算法与人类医学专业知识的使用可能有助于大大减少临床诊断中的错误。本文建立了将机器学习应用于各种医学领域的可行性,包括其他疾病的诊断。
