Achieving Constraints in Neural Networks: A Stochastic Augmented Lagrangian Approach

no code implementations25 Oct 2023 Diogo Lavado, Cláudia Soares, Alessandra Micheletti

Regularizing Deep Neural Networks (DNNs) is essential for improving generalizability and preventing overfitting.

Probabilistic Registration for Gaussian Process 3D shape modelling in the presence of extensive missing data

no code implementations26 Mar 2022 Filipa Valdeira, Ricardo Ferreira, Alessandra Micheletti, Cláudia Soares

We propose a shape fitting/registration method based on a Gaussian Processes formulation, suitable for shapes with extensive regions of missing data.

From noisy point clouds to complete ear shapes: unsupervised pipeline

1 code implementation22 Aug 2020 Filipa Valdeira, Ricardo Ferreira, Alessandra Micheletti, Cláudia Soares

Ears are a particularly difficult region of the human face to model, not only due to the non-rigid deformations existing between shapes but also to the challenges in processing the retrieved data.
