A knowledge representation framework for integration, classification of multi-scale imaging and non-imaging data: Preliminary results in predicting prostate cancer recurrence by fusing mass spectrometry and histology

Abstract: The demand for personalized health care requires a wide range of diagnostic tools for determining patient prognosis and theragnosis (response to treatment). These tools present us with data that is both multi-modal (imaging and non-imaging) and multi-scale (proteomics, histology). By utilizing the information in these sources concurrently, we expect significant improvement in predicting patient prognosis and theragnosis. However, a prerequisite to realizing this improvement is the ability to effectively and qu… Show more

“…A COI approach has typically been shown to be sub-optimal as inter-protocol dependencies are not accounted for. 1 Thus, a number of COD strategies with the express purpose of building integrated quantitative meta-classifiers have recently been presented, including DR-based, 1 kernel-based 11 and feature-based 12 approaches.…”

“…Lee et al 1 proposed data representation and subsequent fusion of the different modalities in a “meta-space” constructed using DR methods such as Graph Embedding 7 (GE). However, DR analysis of a high-dimensional feature space may not necessarily yield optimal results for multi-parametric representation and fusion due to (a) noise in the original N -D space which may adversely affect the embedding projection, or (b) sensitivity to choice of parameters being specified during DR. For example, GE is known to suffer from issues relating to the scale of analysis as well as to the choice of parameters used in the method.…”

“…On the other hand, Jesneck et al [4], on a COI path, optimized a decision-fusion technique to combine heterogeneous breast cancer data. Lee et al [5], proposed a Generalized Fusion Framework (GFF) for homogenous data representation and subsequent fusion in the meta-space using dimensionality reduction techniques. The meta-space is created by projecting the heterogeneous data streams into a space where these scale and dimensionality differences are alleviated.…”
