Elaboration and enhanced usage of data analysis tool DAMIS+

  1. 1. Elaboration and enhanced usage of data analysis tool DAMIS+ Dr. Saulius Maskeliūnas Vilnius University Lithuania Turkey Collaboration Day 4 & 5 December 2017 – Eskişehir / TURKEY
  2. 2. 2 PROJECT IDEA NUMBER: .. (change in 1st slide of master) The Institute of Mathematics and Informatics is a subdivision of Vilnius University. It was a state scientific institute, a budgetary scientific research institution until 30th September 2010; IMI will become Institute of Data Science and Digital Technologies since 2018. IMI was set up to pursue important long-term research for the economy of Lithuania and international cooperation. There are 89 employees at the Institute. 67 researchers are working in the scientific departments, including: 11 doctors habilitatus and 48 doctors (11 doctors have completed habilitation procedure); 19 professors, and 9 docents. There are 52 doctoral students: 9 in Mathematics, 19 in Informatics and 24 in Informatics Engineering; all of them are full-time students. https://www.mii.lt/files/doc/en/imi-reports/research_at_vu_imi_2016.pdf Vilnius University Institute of Mathematics and Informatics (VU IMI)

  6. 6. Project idea description & Key selling points  We have developed and are using [in the environment of National Open Access Research Data Archive (http://midas.lt/), etc.] the data analysis tool DAMIS (http://damis.lt/ ; demo / demo ).  Now DAMIS allows to carry out: (a) data preprocessing (clea- ning, filtering, splitting, trasposing, normalising, feature selection); (b) statistical handling; (c) dimensionality reduction [PCA, SMACOF, DMA, relative DMS, SAMANN, SOM-MDS]; (d) classification, clustering [SOM, MLP, RDF, K-MEANS]; (e) viewing of results [chart and/or matrix view, technical details].  The proposed collaborative project DAMIS+ should develop: (1) methodology, (2) platform, (3) toolbox – possibility to dinamically extend functionality, capabilities of this data analysis tool [with additional methods, etc.] by users themselves, (4) expanded use cases for enhanced usage of data analysis tool.
  7. 7. Partners & expertise  Partners already involved - Vilnius University; - Vilnius University Hospital Santaros Klinikos; Lithuanian Hospitals; - Lithuanian Researchers (mainly from Universities).  Partners looking for - Software and/or research companies/institutions; - Any prospective users of data mining and knowledge discovery, multidimensional data analysis, visualisation, etc. ...

  9. 9. Functionalities and demonstration • DAMIS is a web-based system http://damis.lt (user name/password: demo/demo ); • The web interface does not require any software installation; a web browser is enough for its usage; • There is a possibility to choose high performance computing resources (VU MII cluster – VU MIF supercomputer); • The usage is based on creation of scientific workflows; • The results obtained can be saved in MIDAS and in a user computer.
