Projects

Currently, we work on the following projects:

  • Searching, Mining, and Annotating Human Motion Streams
    Czech Science Foundation, 2019–2021
    Motion capturing devices have become widely available, which resulted in large volumes of 3D human motion data produced in a variety of application domains, ranging from entertainment to medicine. However, automatized processing of such data is a challenging problem because their inherent spatio-temporal nature implies that the same action can be performed in a number of alternatives that vary in speed, timing, or location in space. Moreover, the captured data are imprecise and voluminous, as hundreds of megabytes per hour are obtained during tracking only 3D positions of body joints. Therefore, the employment of basic data-processing paradigms is much more intriguing, when compared to the traditional domains such as text or images. In the proposed project, we aim at developing new theories and technologies for three interconnected open problems of content-based searching, annotating, and mining in motion data streams. Taking into account the fast growth of motion data volumes, a lot of attention will be given to the scalability of proposed solutions.
  • CyberSecurity, CyberCrime and Critical Information Infrastructures Center of Excellence (C4e)
    Ministry of Education, Youth and Sports, 4/2018 – 12/2022
    The project builds on the activities of the Center for Excellence in Cybercrime (C4e) and focuses on creating a new, broader and heavily integrated research strategy divided into three core research programs: Cybersecurity and Cybercrime, Critical Information Infrastructures and Secure/Safe Systems Design, and Law and Jurisprudence. Our lab contributes to the first program that consists of three related areas: (1) Simulation of advanced attacks and efficient defense, (2) Advance analysis of operational data and (3) Similarity management for big-data analytics. The first subprogram investigates methods of modelling of state-of-the-art advanced cyber attacks and their actors. Particularly, we focus on analysis of malicious code in a realistic and controlled environment and active learning of defenders. The second subprogram researches methods for aggregation and correlation of heterogeneous infrastructure events related to operation, security and performance, which enable identification of security anomalies and relational analysis of involved actors. The third subprogram aims at application of metric space paradigm of similarity for analysis of the infrastructure events. Theories, paradigms, and technologies, which make possible knowledge discovery on the large scale will be developed. All three subprograms span several cross-disciplinary topics, namely simulation, education, forensics and knowledge mining.
  • Complex Analysis and Visualization of Large-scale Heterogeneous Data
    Ministry of the Interior, Security Research for the Needs of the State, 2017–2020
    The project aims to develop a distributed system for comprehensive analysis of big heterogeneous data – in particular, digital artifacts acquired during police investigations. Using an integrated uniform solution, the system will enable its users to analyze and visualize complex relationships and contexts of identifiable real-world entities, both by interactive data analyses, and by continuous notifications about monitored activities (based on pre-defined behavior patterns).
