Query: REFINED (REpresentation of Features as Images with NEighborhood
  Dependencies): A novel feature representation for Convolutional Neural
  Networks   Deep learning with Convolutional Neural Networks has shown great promise in
various areas of image-based classification and enhancement but is often
unsuitable for predictive modeling involving non-image based features or
features without spatial correlations. We present a novel approach for
representation of high dimensional feature vector in a compact image form,
termed REFINED (REpresentation of Features as Images with NEighborhood
Dependencies), that is conducible for convolutional neural network based deep
learning. We consider the correlations between features to generate a compact
representation of the features in the form of a two-dimensional image using
minimization of pairwise distances similar to multi-dimensional scaling. We
hypothesize that this approach enables embedded feature selection and
integrated with Convolutional Neural Network based Deep Learning can produce
more accurate predictions as compared to Artificial Neural Networks, Random
Forests and Support Vector Regression. We illustrate the superior predictive
performance of the proposed representation, as compared to existing approaches,
using synthetic datasets, cell line efficacy prediction based on drug chemical
descriptors for NCI60 dataset and drug sensitivity prediction based on
transcriptomic data and chemical descriptors using GDSC dataset. Results
illustrated on both synthetic and biological datasets shows the higher
prediction accuracy of the proposed framework as compared to existing
methodologies while maintaining desirable properties in terms of bias and
feature extraction.
