Two- and Three-dimensional Face Recognition under Expression Variation
… they are not directly applicable when only a single sample image per subject is available. This problem is addressed in this thesis by introducing expression subspaces which can be used for synthesizing new expression images from subjects with only one sample image. It is proposed that by …

Developing Bottom-Up, Integrated Omics Methodologies for Big Data Biomarker Discovery
… transcriptomics, and genomics) view of a single sample or patient. Previously, biologists assumed a strict adherence to the central dogma: replication, transcription and translation. Recent studies in genomics and proteomics emphasize that this is not the case. We must employ big-data …
