Beyond TDA – Persistent Topology and its Applications in Data Sciences

Online workshop “Beyond TDA–Persistent topology and its applications in data sciences“, August 28-30, 2021  


Topological data analysis (TDA) and TDA-based machine learning models have achieved great successes in various areas, such as materials, chemistry, biology, sensor networks, shape analysis, scientific visualization, dynamics systems, and image/text/video/audio/graph data analysis. Beyond TDA, various other geometric, topological and combinatorial models have been developed for representation, featurization, and analysis, including:

  • Multidimensional persistence, Zig-zag persistence, persistent local homology, 
  • Reeb graph, discrete Morse theory, Conley index, 
  • Path complex, Neighborhood complex, Dowker complex, hypergraph, and their persistent homology, 
  • Geometric anomaly detection, discrete geometry, discrete exterior calculus, etc, 
  • Spectral graph, spectral simplicial complex, spectral hypergraph, etc, 
  • Graph/Hodge/Tarski Laplacian, p-Laplacian, topological Dirac, 
  • Cellular Sheaves, 
  • Persistent functions, persistent spectral, persistent Ricci curvature, etc. 

The application of these models in data analysis can be generalized into four stages, i.e., data, topology, feature and learning. Essentially, data are transformed into certain topological representations. Intrinsic geometric/topological/combinatorial features are obtained from these representations and then further input into learning models. This workshop is supported by School of Physics and Mathematical Sciences, Nanyang Technological University, Singapore.

Postdoc in Topological and Geometric Machine Learning for Marine Sustainability at University of Bergen

I’m happy to announce a 3-year postdoctorial position in topological and geometric machine learning for marine sustainability at the University of Bergen. The application deadline is on October 31. 

See for the full advertisement and application instructions.

Please contact Nello Blaser ( for any inquiries. 

Postdoc, TDA for NLP, Düsseldorf

I am advertising a postdoc position at the intersection of topological data analysis, natural language processing and machine learning.

duration: 3 years
starting date: 1 October 2021
location: Heinrich Heine University Düsseldorf, Germany

Reflecting its interdisciplinary nature, the position is associated both with my group (Topology and Geometry) and with the research group of Prof. Milica Gasic (Dialogue Systems and Machine Learning). Prior experience in one or more of the named areas would be beneficial, but we are willing to consider outstanding candidates from other areas of mathematics.

The position will be paid at the TV-L E13 scale (see for more information). It comes with moderate teaching duties (2 times 90 minutes per week during teaching periods), which could be arranged to be of direct relevance for the intended research. Working knowledge of German would be beneficial but is not essential.

Applications and enquiries should be directed to by 30 August.

CfP: Applications of Topological Data Analysis to Big Data

***** Call for Papers: Workshop on Applications of Topological Data Analysis to Big Data at IEEE BigData 2021 *****

Topological Data Analysis (TDA) is a growing area of research that focuses on studying the “shape” of data. Tools (such as persistent homology) from TDA have been successful in many application areas, including signal processing, computer vision, dynamical systems, and geospatial systems. This workshop will be a venue for researchers and practitioners of TDA to present innovative, state-of-the-art topological methods and novel applications of topological tools to big data.In this workshop, we invite submissions on recent applications of topological data analysis, with a focus on larger datasets. Topics include but are not limited to:

  • TDA applications to graphs, hypergraphs and networks
  • TDA applications in natural language processing
  • TDA applications to image and video analysis
  • TDA applications in dynamical systems and signal processing
  • Topological approaches to spatial and social systems
  • Topological approaches to machine learning
