Workshop description

Big volumes of data are prevailing these days in both science and industry. However the size is not the only problem since raw data representation is complex, mixing various components. Also data understanding and interpreting is difficult when the data is collected on topological manifolds, on biomedical structures or it is simply non-scalar. Therefore, there is a current need for optimal data representation in the sense of mapping the data in a new format better suited for analysis and processing. The aim of the workshop is to consider efficient representations of data involved in machine learning, bioinformatics and signals theory using novel methods coming from advances in constructive frame-based expansions, computational topology, dictionary learning, data mining, advanced data structures or artificial intelligence. Applications of novel data representation and analysis for bio-signals, tomographic imaging or data clustering, classification, association and compression are of particular interest.

The workshop welcomes submissions of original, high-quality papers reporting on the topics listed below.

Paper submission

We invite submissions in the form of:
√ research papers,
√ extended abstracts

Papers of up to 8 pages (in CPS Conference Style) should be electronically submitted through EasyChair.

Research papers must contain original research results not submitted and not published elsewhere. Authors who want to present work in progress or discuss new aspects or a survey of their older research results at the workshop are welcome to submit an extended abstract (up to 4 pages). Papers will be refereed and accepted on the basis of their scientific merit and relevance to the Workshop topics.


The papers accepted for presentation will be included in locally edited proceedings (electronic version on a memory stick). Accepted research papers should be presented at the conference and the best papers will be selected for publication in the post proceedings published by Conference Publishing Services.

Extended versions of the papers accepted and presented at the workshop will be considering to be published as a special issue in the Mathematics and Computer Science Annals of the West University of Timisoara or in SCPE – Scalable Computing: Practice and Experience (SCOPUS indexed). Other possibilities for publication will be formulated soon after the workshop.
