Memory-related cognitive challenges are a common problem among elderly people.
The CoachMyLife project aims at developing a system to help people affected by mild cognitive impairment (MCI) in the accomplishment of everyday tasks in their home environment.
The system will combine different kinds of sensors (cameras, wearables) placed in the user’s apartment, and various detection techniques , with the goal of identifying what the user is currently doing out of a number of specific activities, for which users would want the system to provide assistance/reminders. These targeted activities have been selected based on the feedback provided by potential users, and are mainly related to eating/drinking, medication assumption and personal care and hygiene.
The data collected from sensors will be transferred to a remote server and analyzed, and the results of activity recognition will be uploaded to an online database, to provide integration between the various system components. The results of the activity detection algorithms, combined with a knowledge of the user’s activities schedule, will finally allow the system to provide context-based reminders to users, which will be shown through a tablet (HomeTab) in their apartment.

Multiobjective optimization for transparent tunnel design

The goal of the TOPP (Transparent design of optimal underground connections for smart cities using artificial intelligence technologies) project is to develop an advanced service for designing tunnels in urban environments. The service will facilitate the collaboration of all stakeholders by digitizing the tunnel design process and ensure transparency of final solution selection by providing a common user interface. Within TOPP, our role as subcontractors is to provide support for solving the tunnel design optimization problem given a number of constraints. We are responsible for implementing optimization algorithms that offer a set of best trade-off solutions according to various objectives, such as costs, technical characteristics and environmental impacts. The TOPP project is funded by the Republic of Slovenia and the European Union from the European Regional Development Fund and the XLAB and Elea iC companies.


STRAW: Disentangling the sources and context of day-to-day STRess At Work

Over the past decades, substantial attention has been paid to research focusing on chronic exposure to psychosocial stressors in occupational settings and its adverse impact on chronic disease outcomes. The influence on mental and cardiovascular health in particular has been tested and confirmed by frameworks leading in stress research, such as the Job-Demand-Control-Support model and the Effort-Reward-Imbalance model.

Our project adds new approaches to stress research by including several novel aspects; 1) we focus on day-to-day stress and not on chronic stress, 2) we will detect stress in real-word settings i.e. at work and not in lab studies in which participants get exposed to artificially created stress situations, and 3) we measure work environment risk factors (i.e. stressors), and self-perceived stress outcomes (i.e. consequences of stress) repeatedly i.e. more than twice, as compared to traditional longitudinal/follow-up studies. Additionally, physiological responses to stress and smartphone sensor data will be measured continuously.

Our research question can be summarized as follows. How are relationships between 1) work environment risk factors (i.e. stressors), 2) self-perceived stress outcomes (i.e. consequences of stress) experienced in occupational settings, 3) physiological stress parameters, and 4) context as inferred from smartphone sensor data in office-based workers – employed in academic settings – best modeled?

Incorporating real-world problems into the benchmarking of multiobjective optimizers

T. Tušar

COCO (Comparing Continuous Optimizers) is a state-of-the-art open-source platform for benchmarking optimization algorithms on a black-box setting. However, the test functions from COCO, like other available benchmark suites in multiobjective optimization, are at their core still synthetic and do not incorporate some important properties of real-world problems, such as mixed variables, constraints, expensive evaluations and asynchronous evaluations of objectives. Since only a few real-world multiobjective optimization problems are freely available for research purposes, there is an urgent need to collect real-world problems, models of real-world problems and more realistic synthetic benchmark problems into an open benchmark suite that could be used by any researcher in multiobjective optimization.

The idea of this project is to extend the COCO platform by incorporating real-world problems and their properties in order to bridge the gap between research and application in multiobjective optimization. More specifically, the project will:

– extend COCO’s problem formulation and its fixed-target any-time performance assessment methodology to accommodate specificities of real-world problems,

– provide a new multiobjective benchmark suite consisting of real-world problems, models of real-world problems and synthetic problems containing features of real-world problems, and

– design an algorithm capable of solving problems from the new real-world benchmark suite and make its results available for future comparisons.


SYNERGY – Synergy for Smart Multi-Objective Optimization

B. Filipič, T. Tušar, E. Dovgan, J. Zupančič

Demanding real-world optimization problems with multiple objectives can be solved more efficiently if parallelization is used to execute a number of simulations simultaneously and if the the time-consuming simulations are partly replaced by accurate surrogate models. In this twinning project, JSI’s Computer Systems and Intelligent Systems departments aim to strengthen their research and innovation potential in parallelization and surrogate modelling and to explore the potential of combining the two techniques in smart multi-objective optimization in collaboration with the University of Lille and Cologne University of Applied Sciences.

The objectives of the SYNERGY project are to:
– Unleash the research and innovation potential of JSI in the area of multi-objective optimization by supporting training in parallelization and surrogate modelling and aiding organization of workshops that will foster discovery of new ways of combining parallelization within surrogate modelling;
– Raise the research profile of JSI’s staff and broaden its recognition by increased networking (within the consortium as well as externally) that will result in knowledge transfer, joint publications on the topic of efficient multi-objective optimization in renowned conferences and journals with high impact factors as well as joint future research projects;
– Increase the overall research and innovation potential of Slovenia by disseminating the acquired knowledge on parallelization and surrogate modelling to other Slovenian research organizations through dedicated workshops and by applying this knowledge in future applied projects that will enable the Slovenian enterprises to efficiently tackle their time-consuming optimization problems.

XPERIENCE – Robots Bootstrapped through Learning from Experience

R. Piltaver, M. Gams, A. Ude (Department for automation, biocybernetics and robotics)

The goal of Xperience project is to study generative mechanisms which are key in increasing bandwidth and speed of cognitive development. Current artificial cognitive systems are limited in this respect as they do not yet make efficient use of such generative mechanisms for the extension of their cognitive properties. We will address this problem by structural bootstrapping, which is a method of building generative models, leveraging existing experience to predict unexplored action effects and to focus the hypothesis space for learning novel concepts. This developmental approach enables rapid generalization and acquisition of new knowledge and skills from little additional training data.
