Machine learning has shown promising results in predictive analysis for lung cancer prediction. However, class imbalance in clinical datasets negatively impacts the performance of Machine Learning classifiers, leading to biased predictions and reduced accuracy. In an attempt to address this issue, various data augmentation techniques were applied alongside classification models to enhance predictive performance. This study evaluates data augmentation techniques paired with machine learning classifiers to address class imbalance in a small lung cancer dataset. A comparative analysis was conducted to assess the impact of different augmentation techniques with classification models. Experimental findings demonstrate that K-Means SMOTE, combined with a Multi-Layer Perceptron classifier, achieves the highest accuracy of 93. 55% and an AUC-ROC score of 96.76%, surpassing other augmentation-classifier combinations. These results underscore the importance of selecting optimal augmentation methods to improve classification performance. Furthermore, to ensure model interpretability and transparency in medical decision-making, LIME is utilized to provide insights into model predictions. The study highlights the significance of advanced augmentation techniques in addressing data imbalance, ultimately enhancing lung cancer risk prediction through machine learning. The findings contribute to the growing field of AI-driven healthcare by emphasizing the necessity of selecting effective augmentation-classifier pairs to develop more accurate and reliable diagnostic models. Due to the dataset’s high cancer prevalence (87.45%) and limited size, this work is a preliminary methodological comparison, not a clinical tool. Findings emphasize the importance of augmentation for imbalanced data and lay the groundwork for future validation with larger, representative datasets.  \nKEYWORDS  \nlung cancer prediction, class imbalance, explainable AI, LIME, SMOTE  \n1 Introduction  \nLung cancer is one of the most prevalent causes of cancer deaths worldwide, accounting for approximately 1.8 million deaths annually. Irrespective of the advances in medicine and treatment procedures, early detection is a significant concern. The five-year survival rate of lung cancer is significantly high in the initial stage of detection, but most of the cases are diagnosed in late stages due to the reason that the disease does not sho","cbCaihsYCYwwviCs","https://ap.wps.com/l/cbCaihsYCYwwviCs","pdf",4545139,1,23,"English","en",105,"# Introduction\n## Related challenges and motivation\n## Machine learning for lung cancer risk prediction\n## Class imbalance and data augmentation\n## Study approach and evaluation criteria","[{\"question\":\"What problem does the study focus on in lung cancer prediction?\",\"answer\":\"The study focuses on class imbalance in small lung cancer datasets, which can bias classifiers toward the majority class and reduce sensitivity and recall.\"},{\"question\":\"Which augmentation-classifier combination performs best?\",\"answer\":\"K-Means SMOTE combined with a Multi-Layer Perceptron classifier achieves the highest reported accuracy (93.55%) and AUC-ROC (96.76%).\"},{\"question\":\"How does the study support explainable and transparent predictions?\",\"answer\":\"LIME is used to provide insights into model predictions, aiming to improve interpretability in medical decision-making.\"}]","Lung cancer risk prediction using augmented machine learning pipelines with explainable AI -
