CG Colloquium Thursday April 18th

You are cordially invited to attend our CG Colloquium on Thursday, April 18, 2019,
15:45-17:45h, at Pulse Hall 4 .

The program features the following three speakers:

Title: Enhancing Compression of the Sparse Voxel Directed Acyclic Graph

Abstract: Rendering massive scenes in real time represented as voxels has emerged as an attractive alternative compared to the traditional rendering pipeline. This has been achieved through the development of data structures that can efficiently store the scene data while also being inexpensive to traverse. The Sparse Voxel Directed Acyclic Graph is such a data structure, which losslessly compresses geometry by exploiting the spatial coherence in the scene. We attempt enhance the effectiveness of this compression through modifications to the construction of the graph and investigate possibility of applying lossy compression techniques.

Title: Graph Convolutional Networks for Learning on Point Clouds

Abstract: In the past decade, Convolutional Neural Networks (CNNs) have achieved incredible results. A recent development in the deep learning community is the attempt to generalise the advantages of CNNs from a Euclidean domain to non-Euclidean domains, like graphs and manifolds. Some examples of graph data are social networks, regulatory networks, functional networks, and 3D shapes. We attempt to get an understanding of the methods currently available and aim to improve on the current methodology for learning on point clouds. A tentative conclusion is that the conceptually simple Graph Convolutional Network by Kipf and Welling could be improved for manifolds through the incorporation of the connection Laplacian from vector diffusion maps.

Workshop Visual Analytics and Applications

You are all cordially invited to workshop visual analytics and applications, which will take place on 8th of April, from 14:00-17:00 at Pulse-hall 4. Please find detailed program below.

14:00 Jean Daniel Fekete: “Exploring the Evolution of Relationships with Dynamic Hypergraphs”

14:40 Renata Raidou: “Employing Visual Analytics for the Exploration and Prediction”

15:20 Break

15:30 Cagatay Turkay: “Informed computational modelling through visual analytics”

Abstract: With
the increasing availability of computational data analysis and modelling tools
that can be utilised out-of-the-box, the route from data to results is now much
shorter. However, these advancements also come together their own limitations,
and a data scientists need to be aware of the pitfalls and act carefully to
question every observation and method used within each step of the data
analysis process. Visual analytics approaches where interactive visualisations
are coupled tightly with the algorithms offer effective methodologies in
conducting data science in such inquisitive, rigorous ways. This talk will
discuss how visual analytics can facilitate such practices and will look at
examples of research on how data can be transformed and visualised creatively
in multiple perspectives, on how comparisons can be made within different
models, parameters, and within local and global solutions, and on how
interaction is an enabler for such processes.

16:10 Thomas Hollt: Cytosplore: Visual Analytics for Single-Cell Profiling of the Immune System
Recent advances in single-cell acquisition technology have led to a shift towards single-cell analysis in many fields of biology. In immunology, detailed knowledge of the cellular composition is of interest, as it can be the cause of deregulated immune responses, which cause diseases. Similarly, vaccination is based on triggering proper immune responses; however, many vaccines are ineffective or only work properly in a subset of those who are vaccinated. Identifying differences in the cellular composition of the immune system in such cases can lead to more precise treatment. Cytosplore is an integrated, interactive visual analysis framework for the exploration of large single-cell datasets. We have developed Cytosplore in close collaboration with immunology researchers and several partners use the software in their daily workflow. Cytosplore enables efficient data analysis and has led to several discoveries alongside high-impact publications.
