Practices and Infrastructures for Machine Learning Systems : An Interview Study in Finnish Organizations
2022
Using interviews, we investigated the practices and toolchains for machine learning (ML)-enabled systems from 16 organizations across various domains in Finland. We observed some well-established artificial intelligence engineering approaches, but practices and tools are still needed for the testing and monitoring of ML-enabled systems. Peer reviewed
Limiting Carleman weights and conformally transversally anisotropic manifolds
2020
We analyze the structure of the set of limiting Carleman weights in all conformally flat manifolds, 3 3 -manifolds, and 4 4 -manifolds. In particular we give a new proof of the classification of Euclidean limiting Carleman weights, and show that there are only three basic such weights up to the action of the conformal group. In dimension three we show that if the manifold is not conformally flat, there could be one or two limiting Carleman weights. We also characterize the metrics that have more than one limiting Carleman weight. In dimension four we obtain a complete spectrum of examples according to the structure of the Weyl tensor. In particular, we construct unimodular Lie groups whose …
Emotions and Activity Recognition System Using Wearable Device Sensors
2021
Nowadays machines have become extremely smart, there are a lot of existing services that seemed to be unexpectable and futuristic decades or even a few years ago. However, artificial intelligence is still far from human intelligence, machines do not have feelings, consciousness, and intuition. How can we help machines to learn about human feelings and understand their needs better? People take their devices wherever they go, what can devices tell us about their owners? Personal preferences and needs are dependent on emotional and situational contexts. Therefore, emotional and activity aware gadgets would be more intuitive and provide more appropriate information to users. Contemporary weara…
How do parents help? : Parental involvement in children s learning of German as an A2-language
2010
Tämän tutkielman tarkoituksena oli saada selville kuinka kuudesluokkalaisten saksanopiskelijoiden vanhemmat auttavat lapsiaan saksan kotitehtävien teossa ja kokeisiin lukemisessa. Tutkimuksessa pohdittiin, kenen aloitteesta lapsia autetaan, mitä mieltä lapset ovat vanhempiensa avusta ja mistä syistä vanhemmat mahdollisesti eivät auta lapsiaan. Vanhempien lastensa koulunkäyntiin osallistumisen positiiviset vaikutukset on jo todistettu monessa tieteellisessä tutkimuksessa, mutta vanhempien osallistumista A-saksan lukijoiden opiskeluun ei juuri ole tutkittu. Tutkimuksessa pyrittiin myös selvittämään voisiko vanhempien aktiivisuus/epäaktiivisuus vaikuttaa siihen, että saksaa opiskelevien koulu…
Iterative Learning Applied to Hydraulic Pressure Control
2018
This paper addresses a performance limiting phenomenon that may occur in the pressure control of hydraulic actuators subjected to external velocity disturbances. It is demonstrated that under certain conditions a severe peaking of the control error may be observed that significantly degrades the performance of the system due to the presence of nonlinearities. The phenomenon is investigated numerically and experimentally using a system that requires pressure control of two hydraulic cylinders. It is demonstrated that the common solution of feed forwarding the velocity disturbance is not effective in reducing the peaking that occurs as a result of this phenomenon. To improve the system perfor…
Adapting to Teaching in the 21st Century: Helping Teachers to Understand the Pedagogical Content in using Tablets as Learning Tools
2015
The world of knowledge and communication has changed after smart phones and tablets became tools available for everybody. Children are already online on their free time, but at school devices such as smart phones and tablets are not in everyday learning use. In today’s visions of the future school are strongly concentrated on the learning environments and learning methods that emphasizes the role of ICT. The visions are already here and it is possible to bring the future way of learning in to everyday schooling but the focus is on teachers ICT skills and knowledge. Teachers are in a key role in changing the way pupils learn. It is crucial to educate teachers to become experts in ICT-skills …
Compromiso Estudiantil en el Contexto Universitario Colombiano y Desempeño Académico
2014
20 páginas A pesar de la ampliación de la cobertura en la educación superior latinoamericana, persisten graves problemas de deserción que llevan a cuestionar el papel de las experiencias educativas en el fomento del compromiso académico de los estudiantes. Esta investigación se realizó en Colombia y buscó determinar la relación que existe entre el compromiso estudiantil y el desempeño académico de un grupo de universitarios colombianos. El estudio transversal y correlacional empleó la versión en español de la encuesta National Survey of Student Engagement (NSSE) que mide el nivel de participación de los estudiantes en cinco dimensiones: reto académico, aprendizaje activo y colaborativo, int…
Learning English from digital games : Finnish upper secondary school students' perspective on game-enhanced language learning
2017
Tietokoneilla, konsoleilla ja muilla laitteilla pelattavat digitaaliset pelit ovat nousseet niin Suomessa kuin maailmallakin yhdeksi suosituimmista lasten, nuorten ja aikuisten vapaa-ajanviettotavoista. Suurin osa suomalaisista nuorista pelaa tai on joskus pelannut tietokone- tai videopelejä englanniksi (esim. tämä tutkimus), ja on samalla saanut mahdollisuuden kehittää englannin kielen taitoaan motivoivalla, merkityskeskeisellä tavalla. Vaikka aiempien tutkimusten valossa näyttää selvältä, että videopeleillä on kiistaton positiivinen vaikutus kielen oppimiseen (esim. Chik 2012, Mayer 2014), se, millaisena pelaajat itse kokevat pelien parissa tapahtuvan kielenoppimisen, on toistaiseksi jään…

El tratamiento personalizado de la insuficiencia velofaríngea mediante injerto adiposo autólogo de la faringe
2022
La incompetencia velofaríngea (IVP), definida por Lermoyez como un “desajuste anatómico y funcional entre el paladar blando y la faringe durante el habla”, es un problema funcional que requiere una gestión multidisciplinar con un estudio dinámico de las dos estructuras implicadas en el emisión de las palabras mediante la visión directa de los movimientos musculares durante la producción de fonemas. Varios estudios radiológicos han trabajado en la visualización dinámica del cierre velofaríngeo. Pigott fue el primero en introducir la nasofibroscopia en el estudio de la IVP. Ahora, el uso de la resonancia magnética funcional para el estudio del habla está en pleno desarrollo. Éste es un trabaj…
