Breast cancer, if diagnosed and treated early, has a better chance of surviving. Many studies have shown that a larger number of ultrasound images are generated every day, and the number of radiologists able to analyze this medical data is very limited. This often results in misclassification of breast lesions, resulting in a high false-positive rate. In this article, we propose a computer-aided diagnosis (CAD) system that can automatically generate an optimized algorithm. To train machine learning, we employ 13 features out of 185 available. Five machine learning classifiers were used to classify malignant versus benign tumors. The experimental results revealed Bayesian optimization with a tree-structured Parzen estimator based on a machine learning classifier for 10-fold cross-validation. The LightGBM classifier performs better than the other four classifiers, achieving 99.86% accuracy, 100.0% precision, 99.60% recall, and 99.80% for the FI score.
乳腺癌如果早期诊断和治疗,存活的机会就会更大。许多研究表明,每天都会生成更多的超声图像,而能够分析这些医疗数据的放射科医生的数量非常有限。这往往会导致乳腺病变的分类错误,导致高假阳性率。在本文中,我们提出了一种计算机辅助诊断 (CAD) 系统,可以自动生成优化算法。为了训练机器学习,我们从 185 个可用特征中选择了 13 个。使用五种机器学习分类器来对恶性肿瘤与良性肿瘤进行分类。实验结果表明,基于机器学习分类器的树状 Parzen 估计贝叶斯优化在 10 倍交叉验证中表现更好。LightGBM 分类器的性能优于其他四个分类器,准确率达到 99.86%,精度达到 100.0%,召回率达到 99.60%,F1 得分为 99.80%。
