Extending procrustes analysis : building multi-view 2-D models from 3-D human shape samples

Pérez Sala, Xavier (Date of defense: 2015-04-29)

This dissertation formalizes the construction of multi-view 2D shape models from 3D data. We propose several extensions of the well-known Procrustes Analysis (PA) algorithm that allow modeling rigid and non-rigid transformations ...

Size bounds for algebraic and semialgebraic proof systems

Hakoniemi, Tuomas (Date of defense: 2022-03-25)

This thesis concerns the proof complexity of algebraic and semialgebraic proof systems Polynomial Calculus, Sums-of-Squares and Sherali-Adams. The most studied complexity measure for these systems is the degree of ...

Towards a linearly organized embedding space of biological networks

Xenos, Alexandros (Date of defense: 2024-02-02)

(English) The recent technological advances in high-throughput sequencing have yielded vast amounts of large-scale biological omics data that describe different aspects of cellular functioning. These omics data are typically ...
