Evaluating Ensembles on QSAR Classification
- 2009
-
Konferensbidrag (refereegranskat)abstract
- Novel, often quite technical algorithms, for ensembling artificial neural networks are constantly suggested. Naturally, when presenting a novel algorithm, the authors, at least implicitly, claim that their algorithm, in some aspect, represents the state-of-the-art. Obviously, the most important criterion is predictive performance, normally measured using either accuracy or area under the ROC-curve (AUC). This paper presents a study where the predictive performance of two widely acknowledged ensemble techniques; GASEN and NegBagg, is compared to more straightforward alternatives like bagging. The somewhat surprising result of the experimentation using, in total, 32 publicly available data sets from the medical domain, was that both GASEN and NegBagg were clearly outperformed by several of the straightforward techniques. One particularly striking result was that not applying the GASEN technique; i.e., ensembling all available networks instead of using the subset suggested by GASEN, turned out to produce more accurate ensembles.

Generating Comprehensible QSAR Models
- 2009
-
Konferensbidrag (refereegranskat)abstract
- This paper presents work in progress from the INFUSIS project and contains initial experimentation, using publicly available medicinal chemistry datasets, on obtaining comprehensible QSAR models. Three techniques are evaluated on both predictive performance, measured as accuracy, and comprehensibility, measured as model size. The chosen techniques are J48 decision trees and JRip and Chipper decision lists. The results show that J48 obtains superior accuracy and that Chipper performs best of the two decision list algorithms on accuracy. Furthermore, it is seen that, regarding accuracy, all techniques benefit from feature reduction, which almost always results in increased accuracy. Regarding comprehensibility, JRip obtains the smallest models, followed by Chipper, with J48 producing the largest models. For model size, feature reduction is not seen to be universally beneficial; only J48 produces smaller models for the reduced datasets, while both decision list algorithms actually produce larger models on average. The overall conclusion is that, for these datasets, there exists a definite tradeoff between accuracy and comprehensibility that needs to be investigated further.

DAL-21 Det akademiska lärarskapet : Konferensbidrag
- 2021
-
Proceedings (redaktörskap) (refereegranskat)abstract
- Denna skrift innehåller de bidrag som presenterades vid den första DAL-konferensen vid Högskolan i Skövde våren 2021, kallad DAL21. Akronymen DAL står för det akademiska lärarskapet. Bidragen kommer från kollegor vid institutionerna och verksamhetsstödet, pro-rektor och pro-dekan, studentkåren samt två inbjudna talare. Syftet med DAL21 var att främja och stimulera det gemensamma mötet och samtalet om undervisning och undervisningsrelaterade frågor samt sprida de olika former av pedagogiskt och kvalitetsdrivande utvecklingsarbete vilka sker inom ramen för utbildning vid lärosätet.

Proceedings of the 14th SweCog Conference : Linköping 2018, 11-12 October
- 2018
-
Proceedings (redaktörskap) (refereegranskat)abstract
- Welcome to SweCog 2018 in Linköping!This booklet contains the program and short papers for oral and poster presentations at SweCog 2018, this year’s edition of the annual conference of the Swedish Cognitive Science Society. Following the SweCog tradition and its aim to support networking among researchers in cognitive science and related areas, contributions cover a wide spectrum of research.A trend in recent years, also reflected in this year’s conference program, is an increasing number of contributions that deal with different types of autonomous technologies, such as social robots, virtual agents or automated vehicles, and in particular people’s interaction with such systems. This clearly is a growing research area of high societal relevance, where cognitive science - with its interdisciplinary and human-centered approach - can make significant contributions.We look forward to two exciting days in Linköping, and we thank the many people who have contributed to the organization of this year’s SweCog conference, in particular of course all authors and reviewers! The organization of SweCog 2018 has been supported by the Faculty of Arts and Sciences, the Department of Culture Communication (IKK), and the Department of Computer Information Science (IDA) at Linköpping University, as well as Cambio Healthcare Systems and Visual Sweden.Tom Ziemke, Mattias Arvola, Nils Dahlbäc and Erik Billing

Proceedings of the 15th SweCog Conference
- 2019
-
Proceedings (redaktörskap) (refereegranskat)abstract
- In an article published in Nature: Human Behavior, Nunez et al. (2019) asks What happened to cognitive science? The authors review bibliometric and socio-institutional aspects of the field and argues that the transition from a multi-disciplinary program to a mature inter-disciplinary coherent field has failed. Looking at the Swedish environment, we can nothing but agree. Many of us identifying ourselves as researchers in cognitive science are working at departments primarily focused at other disciplines, teaching within other objects and publishing in journals and conferences adjacent to the field. The diversity of cognitive science is also present in the number of directions that has has evolved over the years. The embodied approaches that many of us align with are not evolving towards a coherent view, but is today found under numerous labels such as situated cognition, distributed cognition, extended cognition, and enactive cognition. The so called 4E perspectives on the field have now ventured beyond the four, and is today more often referred to as the multi-E framework.While we agree with Nunez et al. that we remain a multi-disciplinary, multi-perspective, and multi-method group of researchers who may share an interest for the science of the mind, rather than a coherent approach or perspective, we disagree that this entails a failure for the enterprise of cognitive science. We dare to say that the Sweish Cognitive Science Society has embraced the multi-perspectives idea by adopting an inclusive approach in the selection of research and methods presented at our conferences. We hope that SweCog will remain a forum for inclusive discussions, working against discipline conformism and isolation, in a time where both public and scientific debate is increasingly shattered.

Proceedings of the 16th SweCog Conference
- 2021
-
Proceedings (redaktörskap) (refereegranskat)abstract
- We welcome you to the 16’th SweCog conference! After the 2020 meeting had to be cancelled, due to the unusual circumstances of facing a worldwide pandemic, we look forward to finally meet again, although the pandemic makes us meet virtually and not in person. Fittingly, an emerging theme of this year’s meeting is virtual reality. A technology which creates new ways of interacting with each other and with the world. It is not only a subject of active research, but increasingly also a medium for new creative experiments or applications, as evidenced by one of our keynote speakers this year. VR has become now a more widely available tool in different areas of research, and probably has made its full and final impact not yet. SweCog 2021 also features a nod to the word usability day. As technology becomes increasingly present in our daily lives, not the least emphasized through the pandemic, we believe that cognitive science has an important role as a field of research informing the design of usable digital artifacts. As the University of Skövde stands as one example of the close relation between cognitive science and user experience design, we take the opportunity to celebrate the topic of Cognitoon and UX. This meeting has been organized jointly by the Interaction lab and the Cognitive Neuroscience lab of the University of Skövde. We are glad to see this interaction happening between the two labs and the two fields. We hope this is not perceived as an “invasion” of the brain scientists documenting the failure of cognitive science as a field (see Nunez et al., 2019), but rather a collaborative move of finding synergies in our research. In this spirit, we hope our meetings continue to bring people together from different parts of Sweden, from different departments, and maybe also from more different disciplines, to discuss our latest research. And despite our enthusiasm for virtual reality, we sincerely hope the next meeting will allow us to meet again in person.
