Abstract:Missing values and class imbalance are issues frequently found in databases from real-world scenarios, including cancer classification. Impacts on the performance of Machine Learning (ML) models can be observed if these issues are not properly addressed prior to the analysis. In this paper, a combined solution with missing data imputation using kNN and cluster-based undersampling using k-means is proposed, focusing on pancreatic cancer classification. Different data subsets were generated by combining differen… Show more
