In the current scientific age, the measurement technology has considerably improved and diversified producing data in different representations. Traditional machine learning and data mining algorithms can handle data only in a single representation in their standard form. In this contribution, we address an important challenge encountered in data analysis: what to do when the data to be analyzed are represented differently with regards to the resolution? Specifically, in classification, how to train a classifier when class labels are available only in one resolution and missing in the other resolutions? The proposed methodology learns a classifier in one data resolution and transfers it to learn the class labels in a different resolution. Furthermore, the methodology intuitively works as a dimensionality reduction method. The methodology is evaluated on a simulated dataset and finally used to classify cancers in a real–world multiresolution chromosomal aberration dataset producing plausible results.
