Despite the growing demand for high-quality digital assets, matching a desired target appearance remains a time-consuming and labor-intensive process. This talk presents a series of methods aimed at improving controllability in both procedural and non-procedural asset editing. First, inverse procedural modeling approaches for vector patterns and procedural implicit shapes are introduced, allowing parameter estimation from examples or through in-viewport edits. Finally, a method for structured texture synthesis is presented, expanding a small user-designed sketch into large-scale, high-quality and tileable textures through a diffusion model pipeline. Together, these approaches aim to make asset creation more controllable, efficient, and accessible for both novice and experienced artists. Bio: Marzia Riso is a postdoctoral researcher at the Centre Inria drsquo;Universiteacute; Cocirc;te drsquo;Azur.She received her PhD with honors in Computer Graphics from Sapienza University of Rome, under the supervision of Professor Fabio Pellacini. During her PhD, she also spent six months at Adobe Research in Paris, France. Her research mainly focuses on developing methods to improve controllability in asset editing tasks, including synthesis and inverse procedural modeling techniques for 2D and 3D content. She has also worked on geometry processing applications aimed at extending vector graphics operations to the manifold domain. .

Bos; Provenienza: University of Calgary; Data inizio: 2026-04-20; Ora inizio: 12.30; Note orario: Aula H; Referente interno: Giacomo Albi; Riassunto: Neural Nets generate outputs according to a specific recipe, i.e., they form a certain family of (vector valued) functions, determined by a typically large number of parameters (the weights). Training a Neural Net means to adjust the parameters to produce a desired output, i.e., find a good approximation to a given output function from the family of functions produced by the Net. In this course we will explore, in relation to classical approximation by polynomials and splines, how good an approximation can be so obtained. The course will be completely self contained.

Among the questions that remain especially significant today are how to measure the simplicity of a proof, how to assess its readability, and how to evaluate the interestingness of a theorem. Each of these questions matters in its own right. In this talk, however, I will consider them specifically in relation to automated theorem proving and theorem finding in geometry. I will suggest that these three questions can be viewed as closely connected, and that, when approached from this perspective, they offer a fruitful way of understanding both the process and the products of automated reasoning in geometry. ---.

The main goal is to present Gaussian Process regression as a flexible probabilistic framework for modeling unknown dynamics, quantifying uncertainty, and incorporating data-driven corrections into control design. After introducing the foundations of Gaussian Process regression, kernels, hyperparameter learning, and prediction with uncertainty estimates, the course will focus on applications motivated by geometric mechanics and control. In particular, we will discuss how Gaussian Processes can be used to learn and approximate dynamics in mechanical systems of Lagrangian type, where structure, physical interpretability, and control relevance play a central role. We will then illustrate these ideas in applications to quadrotor systems, emphasizing residual dynamics learning, model improvement, and uncertainty-aware control. Finally, the course will address the learning of nonholonomic systems, highlighting both the opportunities and the challenges that arise when data-driven methods are combined with kinematic and dynamic constraints. The course is intended to build a bridge between machine learning and control theory, showing how Gaussian Processes can serve as a rigorous and practical tool for modeling, prediction, and control of complex dynamical systems.
