Toward Self-Aware Robots

2018

Despite major progress in Robotics and AI, robots are still basically “zombies” repeatedly achieving actions and tasks without understanding what they are doing. Deep-Learning AI programs classify tremendous amounts of data without grasping the meaning of their inputs or outputs. We still lack a genuine theory of the underlying principles and methods that would enable robots to understand their environment, to be cognizant of what they do, to take appropriate and timely initiatives, to learn from their own experience and to show that they know that they have learned and how. The rationale of this paper is that the understanding of its environment by an agent (the agent itself and its effect…

Hybrid Learning Situation as a Challenge for Design

2016

In the paper, we address the physical learning space and focus on designing enabling settings for learning. New practices emerge from an accelerating context change and a rapid adoption of novel ICT solutions. Educational institutions and professionals strive to implement effective settings and instructional methods in order to facilitate an acquisition of the 21st century skills. Little attention is paid to changes that take place at the level of interpersonal communication, let alone their possible impacts in the long run. As the methods and the settings diversify, and the whole learning landscape turns hybrid, a good fit between the setting and the instructional method is a daily design …

Farm-Scale Crop Yield Prediction from Multi-Temporal Data Using Deep Hybrid Neural Networks

2021

Farm-scale crop yield prediction is a natural development of sustainable agriculture, producing a rich amount of food without depleting and polluting environmental resources. Recent studies on crop yield production are limited to regional-scale predictions. The regional-scale crop yield predictions usually face challenges in capturing local yield variations based on farm management decisions and the condition of the field. For this research, we identified the need to create a large and reusable farm-scale crop yield production dataset, which could provide precise farm-scale ground-truth prediction targets. Therefore, we utilise multi-temporal data, such as Sentinel-2 satellite images, weath…

A method for anomaly detection in hyperspectral images, using deep convolutional autoencoders

2017

Menetelmä poikkeavuuksien havaitsemiseen hyperspektrikuvista käyttäen syviä konvolutiivisia autoenkoodereita. Poikkeavuuksien havaitseminen kuvista, erityisesti hyperspektraalisista kuvista, on hankalaa. Kun ongelmaan yhdistetään ennalta tuntematon data ja poikkeavuudet, muodostuu ongelma vielä laajemmaksi. Spektraalisten poikkeavuuksien havaitsemiseen on kehitetty useita eri menetelmiä, mutta spatiaalisten poikkeavuuksien havaitseminen on huomattavasti hankalempaa. Tässä työssä esitellään uudenkaltainen menetelmä sekä spatiaalisten että spektraalisten poikkeavuuksien samanaikaiseen havaitsemiseen. Menetelmä on suunniteltu erityisesti spektraaliselle datalle, mutta soveltuu myös perinteisil…

Project Based Teacher Education to Develop Materials, Instruction and Culture for Phenomenon-Based Steam Projects with Pupils in Schools

2018

In Finland, the most radical ongoing school reform is fading out the borders around school subjects to better prepare young people for future challenges. The new National curricular guidelines include phenomenon - based learning (PhBL) at all school levels. In teacher education, we have adopted a project - based approach for accustoming teachers to this change. Communities of learners with diverse areas of expertize are called together to accomplish projects, along with student teachers. The driving questions are directing the development of materials and guidance to realize cross - subject educational projects with pupils in schools. We are applying Ajzen’s Theory of Planned Behaviour to e…

The role of ICT in primary education : pupils' views about iPad-oriented oral communication tasks in English lessons (5th grade)

2014

Tämä tutkimus käsittelee tietotekniikan roolia alakoulun opetuksessa oppilaan näkökulmasta. Tällä hetkellä alakoulua käyvät oppilaat kuuluvat uuteen, teknologiaorientoituneeseen sukupolveen, ja tämän vuoksi tutkimuksen yhtenä oletuksena oli, että oppilailla olisi näkemyksiä aiheesta. Tutkimuksen tarkoituksena on kartoittaa, kuinka tietotekniikkaa on hyödynnetty ja kuinka sitä voi käyttää luokkahuoneessa sekä lisäksi selvittää oppilaiden ajatuksia ja toiveita siihen liittyen. Esimerkkitapauksena tutkimuksessa käsitellään alakoulun viidennen luokan englannin tunteja ja niillä opetuksessa käytettävää iPad-tablettitietokonetta. Tutkimuksen keskeiset teemat ovat alakoulun opetus, opetusteknologi…

Apprendimento del tedesco: nuovi approcci nel training della pronuncia sotto il profilo della learner identity

2019

Utilizzare la propria voce fa parte dell’espressione dell’identità personale. Colui che intraprende lo studio di una lingua straniera si trova talora difronte alla difficoltà di articolare suoni e strutture prosodiche differenti dalla sua lingua nativa e altresì lontani dal proprio vissuto: strani ed estranei. Inoltre pregiudizi ricorrenti possono inibire l’attitudine dell’apprendente nei confronti della lingua che sta imparando. Questo contributo propone nuovi approcci alla lingua tedesca orale, diversi da quelli offerti dai libri di testo in uso nelle scuole italiane. Essi partono dal suono della lingua nella sua interezza e tengono conto di ritmo, struttura sillabica e sforzo articolator…

A hot-headed grandma : the use of idiomatic expressions in the compositions of Finnish upper secondary school students

2011

Metaforisuus on tärkeä osa kieltä. Vähitellen myös kielen oppimisessa ja opettamisessa on alettu ymmärtää idiomaattisen kielen merkitys. Uusia tutkimuksia idiomeista ja niiden oppimisesta tehdään jatkuvasti ympäri maailmaa, myös Suomessa. Tämän tutkielman tarkoituksena oli selvittää, paljonko suomalaiset lukio-opiskelijat käyttävät idiomaattisia ilmauksia tuotoksissaan. Lisäksi tutkielmassa etsittiin eroja idiomaattisten ilmausten käytössä eritasoisten opiskelijoiden välillä, tarkasteltiin sitä, millaisia ilmauksia käytetään sekä sitä, millaisia ongelmia kyseisten ilmausten käyttö aiheuttaa. Aineisto kerättiin kahdesta koulusta 3. vuosikurssin kursseilta. Abiturientit eli kolmannen vuoden o…

A Cognitive Architecture for Robotic Hand Posture Learning

2005

This paper deals with the design and implementation of a visual control of a robotic system composed of a dexterous hand and video camera. The aim of the proposed system is to reproduce the movements of a human hand in order to learn complex manipulation tasks or to interact with the user. A novel algorithm for robust and fast fingertips localization and tracking is presented. A suitable kinematic hand model is adopted to achieve a fast and acceptable solution to an inverse kinematics problem. The system is part of a cognitive architecture for posture learning that integrates the perceptions by a high-level representation of the scene and of the observed actions. The anthropomorphic robotic…
