Artificial Neural Network learners induced from complex and highlyimbalanced data sets tend to yield classification models that are biasedtowards the overrepresented (majority) class. Although someapproaches in the literature address this issue, they

Dealing with missingness in time series data is a very important, but oftentimes overlooked, step in data analysis. In this paper, the nature of time series data and missingness mechanisms are described to help identify which imputation method should
