Mašīnmācīšanās uzdevumu risināšanai interaktīvās tekstuālās vidēs

2021

Interaktīvas tekstuālas piedzīvojumu spēles var izmantot, lai pārbaudītu mašīnmācīšanās aģentu spējas tikt galā ar dažādiem izaicinājumiem, kas saistīti ar dabiskās valodas izpratni, problēmu risināšanu un atbilžu meklēšanu, vai tādas darbības izvēles stratēģiju apgūšana, kas vispārinās uz iepriekš nesastaptām vidēm. TextWorld platforma ir šādiem pētījumiem domāts ietvars un palīgrīki, ar kuru palīdzību var darbināt daudzas iepriekšpublicētas teksta piedzīvojumu spēles, vai arī definēt un ģenerēt jaunas spēles, dažādās sarežģītības pakāpēs un gandrīz bezgalīgās variācijās. Šajā darbā aprakstīta tāda algoritmiska orākula (oracle) ieviešana, kas var veiksmīgi atrisināt spēles no 3 dažādām iep…

Defense versus Opulence? An Appraisal of the Malthus-Ricardo 1815 Controversy on the Corn Laws

2015

This article proposes a rational reconstruction of the arguments of Malthus and Ricardo in their 1815 essays, Grounds of an Opinion and An Essay on Profits, whereby a policy of free corn trade was repudiated and endorsed, respectively. Malthus envisaged defense and (trade-induced) opulence as two mutually alternative options and, if required to make a choice, he had no hesitation in choosing the former. By contrast, Ricardo excluded any such trade-off, arguing that even in the case of war or poor domestic harvest, foreign agricultural countries would be seriously damaged if they opted for restrictions on their corn exports to Great Britain.

New TEL Environments for Vocational Education – Teacher’s Instructional Perspective

2015

Modern vocational education is increasingly taking place in new technology-enhanced learning (TEL) settings. On the one hand, vocational education can benefit from the opportunities of technological development. On the other hand, such technologies may create new challenges for teachers. Therefore, there is a particular need to pay more attention to the dialogic pedagogical approaches in which teaching should be seen as a dialogical practice involving teacher-student interactions that create contextual opportunities for teachers to trigger students’ learning in new TEL settings. This article reports on an exploratory study about the different ways in which teachers’ instructional activities…

Del homo ludens a la gamificación

2017

Resumen: Parece que las ultimas tendencias en educacion pasan por introducir la gamificacion en las aulas y en todas las actividades educativas. La idea de que los contenidos deben interesar a nuestros estudiantes combinada con el convencimiento de que “se aprende mejor jugando”, han llevado a pensar que debemos dar a esos contenidos una forma ludica o, mejor todavia, convertirlos en juegos. ?Es la gamificacion una moda o una oportunidad? Y en el caso concreto de la educacion, ?se trata solo de un recurso metodologico para aprender mas eficazmente o es una caracteristica que deberia tener toda actividad que pretenda ser educativa? ?Como gamificar las clases (de filosofia, en nuestro caso)? …

Infinite games and chain conditions

2015

We apply the theory of infinite two-person games to two well-known problems in topology: Suslin's Problem and Arhangel'skii's problem on $G_\delta$ covers of compact spaces. More specifically, we prove results of which the following two are special cases: 1) every linearly ordered topological space satisfying the game-theoretic version of the countable chain condition is separable and 2) in every compact space satisfying the game-theoretic version of the weak Lindel\"of property, every cover by $G_\delta$ sets has a continuum-sized subcollection whose union is $G_\delta$-dense.

On the best Lipschitz extension problem for a discrete distance and the discrete ∞-Laplacian

2012

Abstract This paper concerns the best Lipschitz extension problem for a discrete distance that counts the number of steps. We relate this absolutely minimizing Lipschitz extension with a discrete ∞-Laplacian problem, which arises as the dynamic programming formula for the value function of some e -tug-of-war games. As in the classical case, we obtain the absolutely minimizing Lipschitz extension of a datum f by taking the limit as p → ∞ in a nonlocal p -Laplacian problem.

Internet Gaming Disorder profiles and their associations with social engagement behaviours.

2021

Abstract Internet Gaming Disorder (IGD), describes the abuse of Internet games with detrimental impact to the real-life social engagement of some gamers. Indeed, evidence suggests that gamers differ on the severity and way in which they express IGD symptoms, as well as their social engagement behaviours. The present study aimed to: a) profile gamers regarding their experience of IGD symptoms and; b) examine how different IGD profiles varied on social engagement behaviours. Methods: A sample consisting of 1032 gamers (18–72 years, Mage = 24) was assessed with the Internet Gaming Disorder Scale 9 Items Short Form (IGDS9-SF) and social engagement questions regarding their participation in empl…

Normanowie, wikingowie a ich przedstawienia w świecie gier komputerowych (na wybranych przykładach)

2018

Pomimo ogromnego postępu w badaniach skandynawskich i normańskich, istnieje jeszcze pole we współczesnej popkulturze, które powiela pewne stare stereotypy. To rynek gier komputero-wych, który kwitnie od ponad czterdziestu lat. Dlatego w artykule przedstawiono to zjawisko chronologicznie – na wybranych przykładach od lat 80. do chwili obecnej. Uczyniono to na pod-stawie tytułów na komputery C, najczęściej strategii i gier R G (Role laying Games), ponieważ ta platforma jest jedną z najstarszych i pomimo szybkiego rozwoju konsol, wciąż im nie uległa. Niestety, nie istnieje literatury naukowa poświęcona wikingom i Normanom w grach wideo, więc do pewnego stopnia badania są pionierskie. Podczas g…

Multiproduct trading with a common agent under complete information: Existence and characterization of Nash equilibrium

2014

This paper focuses on oligopolistic markets in which indivisible goods are sold by multiproduct firms to a continuum of homogeneous buyers, with measure normalized to one, who have preferences over bundles of products. Our analysis contributes to the literature on private, delegated agency games with complete information, extending the insights by Chiesa and Denicolò (2009) to multiproduct markets with indivisibilities and where the agent's preferences need not be monotone. By analyzing a kind of extended contract schedules -mixed bundling prices- that discriminate on exclusivity, the paper shows that efficient equilibria always exist in such settings. There may also exist inefficient equil…
