Dealing with missing data It is not uncommon in real-world applications for our samples to be missing one or more values for various reasons. There could have been an error in the data collection process, certai

Abstract Incomplete data is a common drawback in many pattern classification applications. A classical way to deal with unknown values is missing data estimation. Most machine learning techniques work well with missing values, but they do not focus the missing data estimation to solve the classificat...
High false negative rates (i.e., mineralized locations incorrectly classified as non-mineralized) in MPM will result in a missed opportunity for discovery of a new mineral deposit. Reported solutions for handling the learning difficulties of ML algorithms when trained with imbalanced data regarding ...
(DMUs). Therefore, in such situations, it becomes necessary to set up a strategy to deal with the missing data. In this context, the present work proposes the application of a recent matrix approximation approach, known as low-rank matrix completion, for preprocessing missing data in DEA. ...

Then we have to verify that clean_data was called once, with the return value of load_data. And, finally, we would need to make sure that the return value of clean_data is what is returned by the get_clean_data function as well. In order to do this, we need to set up the ...
missing data, the performance of the multiple imputation method with the performance achieved when considering only the most probable haplotypic configurations or the true phase. When only the phase is unknown, all methods perform approximately the same to identify disease susceptibility sites. In the...
