Posted in: Final year projects
CT RECONSTRUCTION FROM PARALLEL AND FAN-BEAM PROJECTIONS BY A 2-D DISCRETE RADON TRANSFORM The discrete Radon transform (DRT) was defined by Abervuch et al. as an analog of the continuous Radon transform for discrete data. Both the DRT and its inverse are computable in operations for images of size. In this project, we demonstrate the […]

Comments Off on IDENTIFYING GENE PATHWAYS ASSOCIATED WITH CANCER CHARACTERISTICS VIA SPARSE STATISTICAL METHODS
Posted in: Final year projects
IDENTIFYING GENE PATHWAYS ASSOCIATED WITH CANCER CHARACTERISTICS VIA SPARSE STATISTICAL METHODS We propose a statistical method for uncovering gene pathways that characterize cancer heterogeneity. To incorporate knowledge of the pathways into the model, we define a set of activities of pathways from microarray gene expression data based on the Sparse Probabilistic Principal Component Analysis (SPPCA).
