Neural Multimodal Belief Tracker with Adaptive Attention for Dialogue Systems
2019
Multimodal dialogue systems are attracting increasing attention with a more natural and informative way for human-computer interaction. As one of its core components, the belief tracker estimates the user's goal at each step of the dialogue and provides a direct way to validate the ability of dialogue understanding. However, existing studies on belief trackers are largely limited to textual modality, which cannot be easily extended to capture the rich semantics in multimodal systems such as those with product images. For example, in fashion domain, the visual appearance of clothes play a crucial role in understanding the user's intention. In this case, the existing belief trackers may fail …
Market Timing with Moving Averages: Anatomy and Performance of Trading Rules
2015
The underlying concept behind the technical trading indicators based on moving averages of prices has remained unaltered for more than half of a century. The development in this field has consisted in proposing new ad-hoc rules and using more elaborate types of moving averages in the existing rules, without any deeper analysis of commonalities and differences between miscellaneous choices for trading rules and moving averages. The first contribution of this paper is to uncover the anatomy of market timing rules with moving averages. Our analysis offers a new and very insightful reinterpretation of the existing rules and demonstrates that the computation of every trading indicator can equiva…
MRI (Magnetic Resonance Imaging) in Psychiatry
2001
In recent years, structural and functional magnetic resonance imaging has opened up new avenues to the study of psychiatric disorders. A number of structural changes characteristic for different psychiatric diseases could be delineated by the use of magnetic resonance imaging (MRI). Functional magnetic resonance imaging (fMRI) enables the in vivo investigation of cerebral neuronal activation under cognitive or behavioral activation paradigms. Magnetic resonance spectroscopy (MRS) allows for the study of defined neurochemical substances or pharmacological agents in the human brain. This article presents an overview of the basic principles of the different MRI techniques and representative re…
The effect of time and place dependence when utilizing video lectures
2009
In many learning institutes, diversification of teaching with the help of various technologies has become an essential part of educational arrangements. With the increase in the use of networks for teaching purposes, the use of streaming videos is now one of the possibilities to be reckoned with in trying to increase flexibility in studies. Specially recorded on-demand videos provide the students with better chances to decide when, where and how to study. Information on how students use on-demand videos can be obtained, apart from student questionnaires, from the log files of a media server. These files offer an information source that, on the one hand, is diverse but, on the other, cumbers…
Diversification of adult education with the help of video lectures
2010
For some years now, adult education and working while studying have had an important role in the modern society. Mature-age study brings with it some special features, such as time use limitations, which must be taken into account when creating educational programmes for the students concerned. Above all, flexibility must become a major feature of participation in education. In relation to the Master Studies in Mathematical Information Technology at Kokkola University Consortium, the aim for some years now has been to increase that flexibility by diversifying traditional lecture teaching with the help of real-time and on-demand video lectures. With the help of the results presented in this …
What Can International Finance Add to International Strategy?
2011
This chapter focuses on the role of corporate financial strategies to improve firms’ market valuations, and thus lower their cost of capital. The identification of successful strategies is accomplished within an overall strategic framework and related to how the firm perceives the degree of international financial integration. Five strategies for how to break out of a segmented, thin domestic capital market are highlighted together with historical success cases. The chapter illustrates the linkages between business strategy, firm motivation, and various financial strategies. JEL: F21, F23, F36, G32, G34.
Neurodegeneration in multiple sclerosis: novel treatment strategies.
2012
In recent years it has become clear that the neuronal compartment already plays an important role early in the pathology of multiple sclerosis (MS). Neuronal injury in the course of chronic neuroinflammation is a key factor in determining long-term disability in patients. Viewing MS as both inflammatory and neurodegenerative has major implications for therapy, with CNS protection and repair needed in addition to controlling inflammation. Here, the authors' review recently elucidated molecular insights into inflammatory neuronal/axonal pathology in MS and discuss the resulting options regarding neuroprotective and regenerative treatment strategies.
Multivariate analysis of defensive phase in football: Identification of successful behavior patterns of 2014 Brazil FIFA World Cup
2021
The aim of this study was to identify variables associated with direct recovery of the ball during defensive transitions in elite soccer and to propose a model with certain guarantees of success based on a multivariate analysis in which binary logistic regression was used to explore interaction between variables. 1,722 defensive transitions were analysed in the final stages of the FIFA World Cup 2014 in Brazil and investigated the following variables: duration of defensive transition; possession loss zone; position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, period of the match, position of defence line, zone in which the…
Effect of Match Location, Team Ranking, Match Status and Tactical Dimensions on the Offensive Performance in Spanish ‘La Liga’ Soccer Matches
2019
The aim of this paper was to study the combined effects of tactical and contextual dimensions on achieving offensive performance in open play possessions from Spanish “La Liga” soccer matches. 1860 team possessions from 20 random matches were evaluated by means of multidimensional observation. Multilevel regression models were constructed to predict the probability to achieve offensive performance according to the tactical and contextual dimensions registered in each possession. Performing penetrative actions after recovering the ball (OR = 1.497; 95% CI: 1.022–2.192; P < 0.05), and progressing by fast attacks (OR = 3.588; 95% CI: 2.045–6.294; p < 0.001) or counterattacks (OR = 7.097;…
Extrathoracic Lengthening (Kimura Technique)
2021
Treatment of congenital long gap esophageal atresia is extremely challenging. Cases are rare, variable, and oftentimes complex. Possible treatment options include delayed primary repair after initial gastrostomy, gastric transposition, intestinal interpositions, traction procedures, myotomy, and gastric tube techniques. Treatment strategies often consist of variations and combinations of different approaches.
