DOBRO : a prediction error correcting robot under drifts
2016
We propose DOBRO, a light online learning module, which is equipped with a smart correction policy helping making decision to correct or not the given prediction depending on how likely the correction will lead to a better prediction performance. DOBRO is a standalone module requiring nothing more than a time series of prediction errors and it is flexible to be integrated into any black-box model to improve its performance under drifts. We performed evaluation in a real-world application with bus arrival time prediction problem. The obtained results show that DOBRO improved prediction performance significantly meanwhile it did not hurt the accuracy when drift does not happen.
Revisiting rainfall to explore exam questions and performance on CS1
2015
The Rainfall problem comprises small tasks that have been used to investigate student performance in introductory programming. We conducted several kinds of analyses to inform our understandings of student performance in CS1 relating to this problem. We analyzed implementation approaches and program errors, as in related studies, and also explored the role of test writing vis-a-vis the most common student error. Finally, using correlation analyses and manual inspection of the exam answers, we studied how well the Rainfall problem served as an exam question. The students' implementation choices reflected their familiarity with particular loop constructs, while the single most common error co…
An intelligent learning support system
2017
Fast-growing technologies are shaping many aspects of societies. Educational systems, in general, are still rather traditional: learner applies for school or university, chooses the subject, takes the courses, and finally graduates. The problem is that labor markets are constantly changing and the needed professional skills might not match with the curriculum of the educational program. It might be that it is not even possible to learn a combination of desired skills within one educational organization. For example, there are only a few universities that can provide high-quality teaching in several different areas. Therefore, learners may have to study specific modules and units somewhere e…
Performance of an asymmetric and asynchronous decode-and-forward FBMC relay system
2014
End-to-end link performance of an asymmetric and asynchronous dual-hop decode-and-forward (DF) relay system built up using a causal multirate filter bank multicarrier (FBMC) technique operated under Rayleigh fading is presented. Three main performance measures namely bit error rate (BER), outage probability and channel capacity are used for this evaluation and approximate closed-form expressions for them are also made available. FBMC setup is modeled in exact form without any approximations while customizing to one of the most efficient subcarrier filter. Simulations are carried out in quasi-static multipath fading channels under symmetric, asymmetric, synchronous and asynchronous condition…
Itsemurhan taide : itsemurhan roolit modernissa ja jälkimodernissa taiteessa
2011
Tutkielma kartoittaa itsemurhan esiintyvyyttä modernissa ja jälkimodernissa taiteessa ja pyrkii luomaan typologian niistä erinäisistä rooleista, joissa itsemurhan representaatio tällä reilun sadan vuoden aikajanalla esiintyy. Itsemurhan näkyvyydestä taiteessa tehty aiempi tutkimus on vähäistä ja painottuu modernismia edeltäneeseen taiteeseen, joten tutkielma pyrkii muodostamaan kokonaiskuvaa niukasti tutkitusta aihepiiristä. Tutkimuksen taustalla on ajatus siitä, että taide mahdollistaa itsemurhan kaltaisen tabun käsittelyn tavalla, jota arkikieli ei tue. Siten "itsemurhan taidetta" tarkastelemalla olisi mahdollista nähdä myös itsemurhaan liitettyjä merkityssisältöjä laajemmassakin, kulttuu…
Pariterapian sopivuus parisuhdeväkivallan hoidossa : tilannesidonnainen väkivalta ja intiimi terrorismi
2012
Pariterapian sopivuudesta parisuhdeväkivallan hoitoon on käyty paljon kriittistä keskustelua. Tämän tutkimuksen perusteella pariterapiaan kohdistettu kritiikki liittyy kuitenkin nimenomaan intiimiin terrorismiin, kun taas pariterapian edut tulevat parhaiten esiin tilannesidonnaisen väkivallan hoidossa. Tässä pro gradu -tutkielmassa pyrittiin selvittämään pariterapialle parisuhdeväkivallan hoidossa määriteltyjen kriteerien pohjalta, miten pariterapia soveltuu pariskunnille, joissa esiintyy Johnsonin (2008) määrittelemää tilannesidonnaista väkivaltaa tai intiimiä terrorismia. Pyrkimyksenä oli myös selvittää, miten ACBI- lomake (Abusive and Controlling Behaviour Inventory) ennustaa parin sopiv…
Sprachfehler in Übersetzungen von Witzen aus dem Polnischen ins Deutsche
2017
Ze względu na fakt, iż są to teksty krótkie, mogące przekazywać informacje o danej kulturze, a ponadto rozluźnić atmosferę lekcji, dowcipy stosunkowo dobrze nadają się do zastosowania w nauczaniu języka obcego. W publikacji Jana Ciechanowicza i Katarzyny Jakubowicz-Turbacz Spaßvogel. Witze und Schwanke aus Gegenwart und Vergangenheit (Tarnobrzeg 2005) zaprezentowano dowcipy, których strona językowa wyraźnie wskazuje, iż są to teksty polskie przetłumaczone na język niemiecki. Z uwagi na zawarte w nich liczne interferencje na płaszczyźnie pisowni, leksyki czy gramatyki uczącym się języka niemieckiego posłużyć mogą jako materiał do analizy błędów językowych i wykazania różnic systemowych międz…
Aussprachetraining im DaF-Unterricht in der Lehr- und Lernwelt 3.0.
2018
Everyone who acquires a new language at school or elsewhere has the right to learn good pronunciation. As phonetic errors are foreseeable, this paper begins by delineating deviations in (co)articulation and prosody which are typical of Italian learners of German, with the aim of examining how far these specific, predictable phonetic problems are treated in German textbooks used in Italy. The study shows that even modern textbooks do not consider phonetics in a satisfactory way. Today’s learning world 3.0 – not only interactive, but also shaped for the individual learner – is characterized by a growing number of Computer Assisted Language Learning (CALL) and special Computer Assisted Pronunc…
