| Handling Imperfect 'Big' Data in Decision Support Systems
With ever increasing data volumes, database and information management systems face new challenges. Four important characteristics of `Big' data, commonly known as the four V's, are huge Volume, large Variety in data formats, high Velocity and Veracity. Veracity refers to the trust one has in the data that are being used. In this talk we want to address novel techniques in computational intelligence for the proper handling of veracity problems. Topics being presented include the adequate presentation and handling of data imperfections, data quality assessment and result visualization in (geographic) decision support systems. As case study, aspects from the Belgian Federal project Transnational and Integrated Long-term marine Exploitation Strategies (TILES) will be presented.

|Adaptive mobile robots for environment and agriculture
Robots are more and more present in everyday life to achieve difficult, repetitive and harmful tasks. They are particularly popular in industrial manufacture, such as automotive, and works in assembly line. In such areas, robots are particularly performant and reliable, since the environment is well known and structured. Nevertheless, outdoor robotics is still emergent, even in the field of autonomous cars, since unforeseen situations are ofen encountered, and the structure, such as road signs, may be missing or difficult to sense. This is particularly true in off-road contexts, where a structure is not always available and the conditions of motion are varying deeply and cannot be predicted precisely. In order to be efficient and help people reduce the work hardness in applications such as agriculture, outdoor mobile robots have to adapt their behavior with respect to these conditions and the task to be achieved.
This talk proposes an overview of advanced control technique allowing to take into account the varying and dynamic phenomena disturbing the robot dynamics. In particular, adaptive and robust control techniques allowing to estimate on-line such variations will be presented. They permit to improve the accuracy of mobile robot navigation despite disturbances. Nevertheless, motion control does not address the risk controllability loss (spin around, roll-over) which can quickly occurs in uneven and slippery grounds. Beyond obstacle avoidance, which is deeply studied in mobile robotics, the adaptation of robots behaviour in off-road context must also account for the robot integrity, and possibly depreciated perception (because of light conditions, dust of rain).

In particular, he oversees research into the modeling and control of these robots in order to adapt their behavior to the situations encountered.
|Why Swarm Intelligence seems so appealing for complex problem solving
Nature has been inspiring “computational tool makers” for a long time. This, especially when swarms and colonies can serve well as metaphors for tackling complex problems, as their ability to cope with large dimensional search spaces of highly non-monotonic nature, their flexibility and scalability, and rather low computational cost presents Swarm Intelligence as an appealing set of tools.
In 2008, Bastos Filho and Lima Neto proposed a new metaheuristic in the fast-growing family of swarm intelligence techniques, namely, Fish School Search (FSS). In FSS, the school collectively “swims” (searches) for “food” (candidate solutions) in the “aquarium” (search space). Similarly, to PSO (Particle Swarm Optimization) or GA (Genetic Algorithms), the search guidance in FSS is driven by the merit of individual members of the population and the weight of each fish acts as a factual-memory of its individual success. In contrast with PSO, the weight can obviate the need to keep a log of best positions visited as well as any other topological information. As opposed to GA, the actual location of each fish directly substitutes the need of a chromosome. As for the social reasoning, the barycenter of the whole school can guide expansion and contraction of the school, automatically evoking exploration and exploitation when necessary. In other words, the quality of the search can be inferred from regions where larger ensembles of fish are located (and vice-versa).
In this, some reflections on research avenues of Swarm Intelligence will be offered, focusing on aspects that are sometimes disregarded and might be offered why Swarm Intelligence seems so appealing for complex problem-solving. Along the presentation, FSS and some of its variations will be used to illustrate the key-points that are going to be commented upon.

|A Submodular Approach to Power System Stability
In this talk, I will discuss on-going research in developing scalable control
algorithms that provide verifiable guarantees on power system stability. Power system stability must be enhanced in order to realize large-scale clean energy systems, due to the stability challenges posed by unpredictable renewable energy sources such as wind and solar. Since the power system is inherently complex and nonlinear, current state of the art methods, developed by groups such as the North American Synchrophasor Initiative (NASPI), rely on heuristics informed by domain expertise and “rules of thumb”, which are then verified by simulation studies. Our
insight is that many of the relevant stability problems exhibit inherent submodular structure arising from the physical invariants of the power system. Submodularity is a diminishing returns property that has extensive applications in machine learning but was not explored for power systems prior to our work. The advantage of the submodular approach is that it leads to computationally efficient algorithms with provable optimality guarantees.
We will discuss two problems in this talk, the first being the development of
submodular algorithms for voltage stability, in particular the problem of selecting which buses should inject reactive power in order to ensure that a desired voltage level is achieved at each bus of the system. We will show that widely-used metrics for quantifying the level of voltage stability are in fact submodular functions of the set of buses injecting reactive power. In the second problem, we investigate small-signal stability, which consists of mitigating unstable oscillations between different geographic regions of the power system. Recently, wide-area control schemes, in which a centralized controller receives measurements from different regions, computes control actions, and transmits supplementary damping control signals to distributed generators have been proposed to enhance small-signal stability. These schemes, however, rely on choosing a set of Phasor Measurement Units (PMUs) to send measurements, as well as choosing a set of generators to participate in the control. We formulated the problem of selecting minimum-size sets of generators and measurements in order to guarantee that all unstable modes are stabilized.

| WASTCArD: Wrist and arm sensing technologies for cardiac arrhythmias detection in long term monitoring
Abnormal heart rhythms are a major cause of cardiovascular disease and death in Europe. Sudden cardiac death accounts for 50% of cardiac mortality in developed countries; ventricular tachycardia or ventricular fibrillation is the commonest underlying arrhythmia. In the ambulatory population, atrial fibrillation is the commonest one, and is associated with increased risk of stroke and heart failure, particularly in the aged population. If arrhythmias are detected at an early stage of heart disease, appropriate treatment can be effective, reducing disability and death. However, in the early stages of disease these may be transient, lasting only a few seconds, and thus difficult to detect.
The proposed joint research project through staff exchange activities, will investigate enabling technologies for non-invasive recording heart rhythm during long periods of time (>36h), using a wrist or arm wearable device with novel ECG sensing techniques and embedded real-time cardiac arrhythmia detection processes. The problem of extracting the far-field heart electrogram signal from noise components will be addressed using smart denoising algorithms. The project will impact by establishing a successful international (specifically with Colombia, Venezuela and Brazil) and intersectoral partnership for the development of new technologies addressing a significant cardiovascular healthcare problem. These technologies will be suitable for integration into current e-Health and cardiac information systems, and will impact on healthcare costs reduction by improved efficiency in the diagnosis and early treatment of cardiac disease.

|Big Data Analytics using Deep Learning and Information Theoretical Learning: Applications to Astronomy
Astronomy is facing a paradigm shift caused by the exponential growth of the sample size, data complexity and data generation rates of new sky surveys. To cope with a change of paradigm to data-driven science new computational intelligence, machine learning and statistical approaches are needed. In this talk I will present two main applications. The first is to discriminate periodic versus non-periodic light curves, and then estimate the period of the periodic ones. Light curves are one-dimensional time series of the brightness of a star versus time. We have developed several methods based on the correntropy function (generalized correlation using information theoretical learning concepts), which outperforms conventional approaches. Results using 32.8 million light curves will be presented. Interestingly, some of these techniques can be applied to other problems such as sleep EEG analysis, and I will present preliminary results on this topic too.
The second application is the automated real-time transient detection in astronomical images. The aim is to achieve real-time detection of supernovae and other transients with the Dark Energy Camera. A novel transient detection pipeline was developed. We have been applying convolutional neural nets (deep learning) to discriminate between true transients and bogus transients, among other techniques, e.g non-negative matrix factorization combined with random forests. Results using 1.5 million images will be presented. The new pipeline was successfully tested online in February 2015 finding more than 100 supernovae in a few days of telescope observation.

|Cardiovascular Engineering: challenges in electrical assessment, intervention and assistance of the heart.
Prof. Omar Escalona is a Professor in the School of Engineering and a member if the Engineering Research Institute. He is Director of the Centre for Advanced Cardiovascular Research (CACR) at Ulster University. His ongoing research and impact activities are on: atrial fibrillation solutions with improved QALY outcome difference; highly efficient cordless energy supply systems for artificial hearts and VADs; and Connected-Health enabled cardiovascular healthcare services.
Every heart beat involves electrochemical flow of charged particles which may be sensed on the body surface for assessing the heart’s state of health or any arrhythmic abnormality through multichannel ECG techniques, including challenging body surface cardiac mapping techniques in bipolar far-field body surface locations. Reversely, some heart abnormalities can be terminated by means of electrical intervention in various challenging and effective ways. Finally, overcoming the latter cardiac electrical intervention challenges may provide the long awaited technology solutions for sustainable wireless electrical power supply for the mechanical assistance of the weak and failing heart.
