The Chair of Artificial Intelligence conducts research on new methods of data mining, also such as lack sufficient precision of description, which take into account incomplete cases and various causes of incompleteness. We develop methods of multi-strategic modeling of knowledge, its arithmetic and interrelational analysis of dependencies. We create unique solutions in the field of biomedical image processing and analysis algorithms which support effective diagnosis of malignant melanoma.

Research teams
As part of the research topic „Next-generation tools for federated learning effectively supporting decision support systems with uncertainty”, a research group has been established in the Department of Artificial Intelligence with the main goal of developing methods and tools in federated learning systems taking into account imprecision, uncertainty and data gaps. To this end, it is planned to use multiple data sources to teach effective artificial intelligence models without sharing source data (federated learning with data security and anonymity) taking into account imprecision.
Federated learning (FL) is a particular approach to training machine learning (ML) algorithms in a way that means the data remains private. Specifically, federated learning techniques aim to train machine learning algorithms on multiple distributed devices or servers, each with its own local and private data.
This collaborative approach contrasts with traditional machine learning techniques, which are centralized and rely on collecting all data samples in one unique data set before using them. It also differs from parallel computing-based techniques, which were developed to optimize ML on multiple processors, using a centralized data set that is divided into identically distributed subsets for computation.
The goal of the research is to improve the efficiency of systems supporting federated learning using methods that take into account data uncertainty, guaranteeing member privacy while resisting attacks and ensuring fairness between system members.
In many areas of life, such as industry, medicine or economics, a problem arises when an organization does not have a large enough data set to construct a decision/diagnostic system of sufficient quality. In this case, data from different organizations must be used, which is related to the problem of data sharing. To overcome these problems, federated learning is becoming increasingly popular, enabling automatic learning across distributed networks of autonomous partners without sharing raw data.
An important goal of the emerging team is to strengthen the indicated research area, through cooperation with the University of Rzeszow and the internationally leading Maastricht University.

VISUAL – VERSATILE INFRARED LIGHT SOURCE FOR ADVANCED ILLUMINATION
Project manager: Łukasz Piątek , Ph.D lpiatek@wsiz.edu.pl
Medical and consumer electronics markets drive an ever-growing demand for powerful, compact, high quality and cost-effective femtosecond (fs) sources. Ophthalmic surgery and stent manufacturing in the medical field, post-processing of OLED panels defective pixels and smartphones machining in the consumer electronic field are examples of maturing processes where Ultrafast Lasers (UL) are key enablers. In the global scientific instrumentation market, non-linear multimodal optical microscopy (multiphoton absorption fluorescence or coherent Raman microscopy), high energy photon coherent radiation via high harmonic generation processes, high energy particle beam generation, time-resolved dynamic charge transfer studies in materials are in increasing use in research laboratories. Such increasing business perspectives fuel a worldwide competition for UL manufacturers.The VISUAL project aims to strengthen the leadership of the industrial UL manufacturing partners in the scientific, medical and industrial application fields, based upon a novel design-to-cost and innovative UL platform providing an unprecedented technical versatility. This high-average-power platform will deliver ultrashort optical pulses with pulse-on-demand capability at very high repetition rates (60 MHz) and with extremely broad wavelength tuning ability. The numerous benefits of this platform, designed for multi-purpose applications cases, will be assessed, within the framework of VISUAL, in label-free bio-imaging and medical diagnosis, in “on-chip” particle acceleration for electron-beam therapy, and in advanced fiber and glass microstructuration.

Exploration of incomplete data and biomedical imaging
Project manager: Teresa Mroczek, Ph.D tmroczek@wsiz.edu.pl
As part of this research, two separate goals are proposed: 1) creating new methods for analyzing incomplete data sets and moving away from the commonly used approach in incomplete data mining, i.e. imputing missing attribute values before the mining process for the development of incompleteness interpretation methods and set indicators, and 2) development of new methods enabling quantitative assessment of biomedical images, including mainly the development of a method for automatic classification of digital images of melanocytic skin
