Talk title: Benchmarking Secondary Schools Using Students’ Results at University

Abstract: In this research, we use data on university students’ first-year scores as a means to compare and benchmark secondary schools on their ability to lead students to university success. Data from two universities in Portugal, Portuguese Catholic University (with seven faculties) and the University of Porto (with 14 faculties) were used to compute a number of metrics, based on which secondary schools were compared. The performance of more than 10.000 students from 65 different degrees was explored for a three year period.

There are mainly two research questions addressed in this paper: (1) what are the determinants of success for first-year university students? and (2) what is the role of the secondary school of origin in determining success for first-year university students? The regression model used to test these hypothesis assumes that university success in the first year is a function of student characteristics (e.g., scores on entry to higher education), secondary school characteristics (e.g., private vs. public) and university/course characteristics (e.g., public vs private university and the main scientific area of the course). University success is measured through two measures: number of ECTS finished by first-year university students and the final grade at the end of the first year (this final grade is normalised per degree attended and cohort to allow comparability between different degrees and years). Conclusions from the preliminary analysis point to the importance of scores on entry (based on standardized national exams), but this importance is relatively small in explaining the success of students at the university (it explains to a certain degree the average scores obtained at the end of the first year but not the number of ECTS completed). The type of school appears as the second most important factor in determining student’s success, with public schools performing better than private.

A DEA model was constructed to compare secondary schools on the extent to which they prepare students to university success. For this purpose, a set of outputs relating to success in the first year of higher education was defined (e.g., percentage of students at the top percentile of the degree attended, average number of ECTS completed by the students, and average score of students at the end of the first year, normalised according to the degree attended). The input of the DEA model is the score on the entry of the students, normalised according to the degree attended by each student. This model attempts to evaluate secondary schools by the value added accomplished by their students when attending higher education. This model is unprecedented in the literature, as it evaluates secondary schools based on the performance of students in higher education, which is undisputedly a key objective of secondary school education.

Talk title: High Performance Computing: Platforms and Techniques

Abstract: It is of utmost importance to overcome the challenges of the High Performance Computing (HPC) to advance in the main topics of the modern computation, such as Internet of things, Data Mining, Artificial Intelligence and so on, since they have tremendous computational requirements. Supercomputers provide great computational resources, which can be harnessed by Cloud technology. Moreover, thanks to technological and architectural advances, current HPC platforms are not only located in Supercomputing Centers, but also standalone computers, smartphones, embedded systems can be considered as HPC platforms if they are appropriately exploited. These architectures are based on heterogeneous multi-core processors and they include additional resources to take advantage of different kinds of parallelism in applications. This tutorial revises the keys of the current HPC platforms from the point of view of the hardware technology and software interfaces, with a special focus on the representative HPC applications.

Talk title: Decisions in Human Centric Multiagent Systems: Rationality and Some Cognitive Biases

Abstract: We are concerned with systems in which there are multiple agents, humans or software agents imitating the human judgments, behavior, perception, evaluations, etc. The agents are faced with a set of options (alternatives or courses of action) and should find an option or a set of options that can be considered as the best acceptable by the entire group. The agents provide their testimonies as to their opinions on the goodness of options which can be given as preference relations, utility (valuation) functions, sets of approved/disapproved options, etc. The best option is then found on the basis of these testimonies and also some other aspects like attitudes of the agents. The process is then assumed to be run with the help of a moderator, a “super-agent” who is guiding the process. First of all, the process is meant to involve a consensus reaching step in which the source, usually highly different testimonies of the agents are made closer, i.e. the agents change their testimonies usually persuaded by the moderator. Then, after reaching a “consensus”, i.e. closer testimonies, some group decision making (or voting) tools are used to obtain solutions which are mainly some cores, i.e. sets of options that are undominated with respect to other options in the opinion of most agents. We assume quite a general approach with fuzzy preferences and a fuzzy majority. It is shown that such an approach exhibit, first, some properties of a greedy, or selfish, approach since the agents are just take into account their testimonies. A new approach is proposed in which some fairness occurs in the sense that testimonies of all agents are accounted for. Moreover, as this fairness oriented approach involves changes of the agents’ testimonies, with a fair suggestion of such changes to all agents, a new model is proposed which takes into account some well known cognitive bias, the status quo bias. The cognitive bias is meant in the sense of Kahneman and Tversky, i.e. that people make judgments or decisions in the ways that are systematically different than obtained from traditional economic models, and the cognitive bias does not necessarily lead to bad decisions. Among the cognitive biases the status quo bias,, i.e. that people tend to avoid larger changes, is shown to be promising in the context considered. A possible use of some other cognitive biases is mentioned.

Talk title: Deep learning for understanding human vision

Abstract: How do we recognize what we see? Despite the deceptive ease of perceiving things, explaining how we see turns out to be a supremely difficult task. Only recently advances in computer vision finally brought a class of models, known as deep neural nets, that are capable of matching human and non-human primate performance in several visual perception tasks. Our present aim is to develop these artificial systems further so that they would simultenously (i) predict primate neural and behavioral responses during visual object recognition tasks, (ii) map well onto brain anatomy, and (iii) generalize to novel stimuli similarly to primates. I will first introduce Brain-Score, our composite benchmark for an extensive comparison of deep nets to primate ventral visual stream. Building on the insights gained by performing such benchmarking, I will describe the CORnet family of models that commits to biological realities of the visual cortex. I will further extend our benchmarking to a much wider image set of images, including cartoons and paintings, to test and compare the limits of generalization in humans and machines. Taken together, our approach brings forward a good baseline deep neural network that could serve as a building block towards developing capable artificial cognitive agents.

Talk title: HPC for Tsunami Danger Prediction

Abstract: It takes only 20 min for tsunami wave to approach dry land after earthquake offshore Japan. HPC resources are needed for Tsunami Warning Service. Several algorithms, covering major aspects of tsunami risks mitigation, were optimized to achieve near real-time performance at the modern PC, using Graphic Processing Units (GPU) and/or Field Programmable Gates Arrays (FPGA). Among the algorithms we describe: (a) optimization of the sensor network (deep water pressure recorders or/and GPS stations), (b) filtering tide wave from the measured data, obtained at deep water buoys signal, (c) estimation of initial sea faces displacement at tsunami source, (d) tsunami wave propagation throw the ocean. Performance of the NOAA tsunami simulation tool, the so-called MOST software package, become nearly 100 times faster after optimization for NVIDIA GPU architecture. As the result, we expect calculated wave amplitudes (covering area compared to 1.000*2.000 km) within 12 minutes after the earthquake.

Talk title: Human-Computer Interaction: A Behavioural Approach

Abstract: Academia and enterprises have been very prolific in researching human-computer interaction and the human behaviour issues through controlled studies, surveys, laboratory prototypes and applied case-studies. The results of this research efforts show that there are several key factors involved in Human-computer Interaction activities. These include physiological and psychological indicators, as well as behavioral and even somatic ones.
Stress is a critical component of the human activity, and it shows through physical, mental, or emotional tension, having a high impact in medical or biological contexts. Thus, stress has a great repercussion in psychological conditions such as depression and anxiety. In a corporate environment, workers are under increasing demand for performance, which leads to being under constant pressure. Therefore, their level of stress is greatly affected, presenting significant variations. To tackle these issues, this research aims to produce a new approach in human–computer interaction by developing a distributed multi-modal framework to monitor and assess the psychological stress of people doing high-end computer-related tasks. This is done in a non-intrusive and non-invasive way, using soft sensors to monitoring activities (e.g., task performance and human behaviour).

Talk title: The Laboratory of an Education Economist. Testing Cures for Disadvantaged Students

Abstract: Kristof De Witte overviews his research agenda on socio-economic segregation. In particular, he discusses various quasi-experimental evaluations of interventions to change the odds for disadvantaged students. On the one hand, he presents the effects of additional resources at school level on cognitive and non-cognitive outcomes and illustrates that that extra resources at municipality level only result in grade inflation. On the other hand, he argues that information shocks provided by making school quality information public changes the socio-economic composition of schools. He shows that in the longer run, these findings are alarming as the inability to break the vicious circle for low SES students leads to more school dropout, and that particularly those students have a lower return to education.
