On the use of a metric-space search algorithm (AESA) for fast DTW-based recognition of isolated words
1988
The approximating and eliminating search algorithm (AESA) presented was recently introduced for finding nearest neighbors in metric spaces. Although the AESA was originally developed for reducing the time complexity of dynamic time-warping isolated word recognition (DTW-IWR), only rather limited experiments had been previously carried out to check its performance in this task. A set of experiments aimed at filling this gap is reported. The main results show that the important features reflected in previous simulation experiments are also true for real speech samples. With single-speaker dictionaries of up to 200 words, and for most of the different speech parameterizations, local metrics, a…
Behavioral and Neural Arguments of Motivational Influence on Decision Making During Uncertainty
2020
The scientific world is increasingly interested in motivation, primarily due to the suspected impact on decision-making abilities, particularly in uncertain conditions. To explore this plausible relationship, 28 healthy participants were included in the study and performed decision-making and motivational tasks while their neural activity was recorded. All participants performed the Iowa Gambling Task (IGT) and were split into two groups based on their score, one favorable group with 14 participants who performed advantageously and one undecided group with 14 participants who failed to develop the correct strategy on the IGT. In addition, all participants performed the Effort Expenditure fo…
Writing tasks in EFL teaching : analysis of the writing tasks in Finnish schoolbooks
2015
Perusopetuksen opetussuunnitelman perusteet (2004) englannin kielen kirjoitustaidon osalta jättävät vastuun kirjoitustehtävien suunnittelusta opettajille ja kirjantekijöille. Oppimateriaaleja tutkimalla voidaan saavuttaa tietoa englannin kielen opetuksesta Suomessa. Tutkielma pyrkii selvittämään, minkä tyyppistä kirjoitustaitoa opetetaan suomalaisissa englannin kielen oppimateriaaleissa ja tutkimus keskittyy kirjoitustehtävien painopisteiden tutkimiseen kahden kysymyksen kautta. Ensiksi tutkittiin kirjoitustehtävien sijoittumista muotoa painottavien ja sisältöä painottavien tehtävien väliselle akselille, ja toiseksi selvitettiin, minkälaisia kirjoittamisen taitoja tehtävät harjoittavat. Ain…
Employees' work patterns-office type fit and the dynamic relationship between flow and performance
2021
Organizations must improve their employees’ performance in order to compete effectively. Evidence shows that flow experiences enhance performance. However, a dynamic approach to this phenomenon is needed. Furthermore, different work patterns (based on task profiles) can have specific environmental requirements (office types). This research aims to analyze the dynamic relationship between office workers’ flow and in‐role and extra‐role performance, considering work pattern–office type fit as a predictor of the initial level of each of these three variables. A total of 83 workers participated in this diary study. Results of the latent growth model showed a positive association between: (1) th…
EUROASPIRE IV: A European Society of Cardiology survey on the lifestyle, risk factor and therapeutic management of coronary patients from 24 European…
2016
AIMS: To determine whether the Joint European Societies guidelines on cardiovascular prevention are being followed in everyday clinical practice of secondary prevention and to describe the lifestyle, risk factor and therapeutic management of coronary patients across Europe. METHODS AND RESULTS: EUROASPIRE IV was a cross-sectional study undertaken at 78 centres from 24 European countries. Patients <80 years with coronary disease who had coronary artery bypass graft, percutaneous coronary intervention or an acute coronary syndrome were identified from hospital records and interviewed and examined ≥ 6 months later. A total of 16,426 medical records were reviewed and 7998 patients (24.4% female…
Relación entre complejidad y dificultad en tareas con patrones lineales reiterativos en estudiantes de 5 años
2018
Una de las finalidades de la enseñanza de las matemáticas en Educación Infantil es fomentar el pensamiento lógico, la creatividad y la capacidad para resolver problemas de los estudiantes. Entre las actividades escolares propias de estas edades es habitual encontrar tareas de identificación y continuación de patrones lineales de repetición. Esta actividad puede ser estudiada desde un contexto de resolución de problemas en el que el estudiante debe discriminar la información superflua de aquella que le permite obtener la regla de generación de la serie y resolver la tarea. Diferentes variables como la longitud del núcleo de repetición, el número de descriptores, su naturaleza o la aparición …
Early handling effect on female rat spatial and non-spatial learning and memory
2014
This study aims at providing an insight into early handling procedures on learning and memory performance in adult female rats. Early handling procedures were started on post-natal day 2 until 21, and consisted in 15 min, daily separations of the dams from their litters. Assessment of declarative memory was carried out in the novel-object recognition task; spatial learning, reference- and working memory were evaluated in the Morris water maze (MWM). Our results indicate that early handling induced an enhancement in: (1) declarative memory, in the object recognition task, both at 1h and 24h intervals; (2) reference memory in the probe test and working memory and behavioral flexibility in the…
Colour reverse learning and animal personalities: the advantage of behavioural diversity assessed with agent-based simulations
2012
Foraging bees use colour cues to help identify rewarding from unrewarding flowers, but as conditions change, bees may require behavioural flexibility to reverse their learnt preferences. Perceptually similar colours are learnt slowly by honeybees and thus potentially pose a difficult task to reverse-learn. Free-flying honeybees (N = 32) were trained to learn a fine colour discrimination task that could be resolved at ca. 70% accuracy following extended differential conditioning, and were then tested for their ability to reverse-learn this visual problem multiple times. Subsequent analyses identified three different strategies: ‘Deliberative-decisive’ bees that could, after sev…

Learning competitive pricing strategies by multi-agent reinforcement learning
2003
Abstract In electronic marketplaces automated and dynamic pricing is becoming increasingly popular. Agents that perform this task can improve themselves by learning from past observations, possibly using reinforcement learning techniques. Co-learning of several adaptive agents against each other may lead to unforeseen results and increasingly dynamic behavior of the market. In this article we shed some light on price developments arising from a simple price adaptation strategy. Furthermore, we examine several adaptive pricing strategies and their learning behavior in a co-learning scenario with different levels of competition. Q-learning manages to learn best-reply strategies well, but is e…
