Detection of Breast Cancer Through Clinical Data Using Supervised and Unsupervised Feature Selection Techniques

Abstract

Breast cancer is one the most critical disease and suffered many people around the world. The efficient and correct detection of breast cancer is still needed to ensure this medical issue although the researchers around the world are proposed different diagnostic methods for detection of this disease, however these existing methods still needed further improvement to correct and efficient detection of this disease. In this study, we proposed a new breast cancer identification method by using machine learning algorithms and clinical data. In the proposed method supervised (Relief algorithm) and unsupervised (Autoencoder, PCA algorithms) techniques have been used for related features selection from data set and then these selected features have been used for training and testing of classifier support vector machine for accurate and on time detection of breast cancer. Additionally, in the proposed approach k fold cross validation method has been used for model validation and best hyperparameters selection. The model performance evaluation metrics have been used for model performance evaluation. The BC data sets have been used for testing of the proposed method. The analysis of experimental results has been demonstrated that the features selected by Relief algorithm are more related for accurate detection of Breast cancer instead of features selected by Auotencoder and PCA algorithms. The proposed method has been attained high results in terms of accuracy on selected feature selected by Relief algorithm and achieved 99.91% accuracy. We have been employed McNemar's statistical test for performance comparison of our different models. Further, the proposed method performance has been compared with baseline methods in the literature and the proposed method performance is high as compared to base line methods. Due to the high performance of the proposed method (Relief-Support vector machine) we highly recommended it for the diagnosis of breast cancer. In addition, the proposed method can be easily incorporated into the healthcare system for reliable diagnosis of Breast cancer.

Diagnostic Approach for Accurate Diagnosis of COVID-19 Employing Deep Learning and Transfer Learning Techniques through Chest X-ray Images Clinical Data in E-Healthcare

“…The holdout cross-validation mechanism is used for model training and validation [5,8]. In this study chest X-ray images data sets were divided into 70% and 30% for training and teasing of the model for all experiments.…”

“…Due to AI these diseases are effectively diagnosis at early stages and ensuring the proper treatment and recovery of patients. The AIbased computer-aided diagnosis (CAD) systems accurately diagnose diseases than medical professionals because the medical experts do not correctly interpret the images of chest X-ray and CT Scan to diagnosis the disease at an early stage [3][4][5][6][7][8].…”

“…Several performance measures were calculated to verify the applicability and the efficiency of our CAD system [49]. Performance evaluation measures include accuracy (ACC), sensitivity (SEN), specificity (SPE), the area under the curve (AUC), and the Dice similarity coefficient (DSC).…”

Using Embedded Feature Selection and CNN for Classification on CCD-INID-V1—A New IoT Dataset

“…The embedded feature selection scheme has been preferred over the filter and wrapper methods [ 56 , 57 , 58 ], and has seen success in fields such as bioinformatics [ 59 , 60 ], and medical research [ 61 , 62 , 63 , 64 ], but remains relatively new in the field of IoT security.…”
