Title: Approaches to learning strictly-stable weights for data with missing values
Authors: G. Beliakov, D. Gómez, S. James, J. Montero, J.T. Rodríguez
The problem of missing data is common in real-world applications of supervised machine learning such as classification and regression. Such data often gives rise to the need for functions defined for varying dimension. Here we propose optimization methods for learning the weights of quasi-arithmetic means in the context of data with missing values. We investigate some alternative approaches depending on the number of variables that have missing values and show results for several numerical experiments.
