Title :  

Metaheuristic optimization in Hyperbolic space. 

Abstract : 

 Hyperbolic spaces have recently achieved acceleration in the context of machine learning of their high capacity and tree-likeliness structures, taxonomies, text, and graphs. With the same dimension, a hyperbolic vector can represent richer information than a Euclidean vector. In this paper, we propose Metaheuristic optimization algorithms in hyperbolic space. Considering that the most popular optimization tools have not been generalized in hyperbolic space, we design optimization algorithms according to the specific property of the hyperbolic manifold.

However, a major bottleneck here is the obscurity of hyperbolic space and a better comprehension of its gyrovector operations. We aim to introduce researchers and practitioners in the metaheuristic community to the hyperbolic equivariant of the Euclidean operations necessary to tackle their application to Metaheuristic optimization.

We conduct experiments on various metaheuristic algorithms in hyperbolic space.

Title :  

Interactive Visualization for Surgery Planning and Medical Training

Abstract : 

 Three-dimensional (3D) imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) are routinely used in medicine. This has led to an increasing flow of high-resolution, high-dimensional image data that needs to be qualitatively and quantitatively analysed. This requires accurate segmentation of the image into relevant structures such as bones, soft tissue, liver, or blood vessels. In this talk, I will present some of the powerful methods for interactive image segmentation and visualization we have developed. We combine volume rendering with 3D texture painting to enable quick identification of the objects of interest. The user can work on the surfaces in 3D as well as on 2D slices. The methods are implemented on the GPU and can achieve real-time update rates for large volumes. Our system is used in clinical research by the clinicians.
