Towards digital cognitive clones for the decision-makers: adversarial training experiments
2021
Abstract There can be many reasons for anyone to make a digital copy (clone) of own decision-making behavior. This enables virtual presence of a professional decision-maker simultaneously in many places and processes of Industry 4.0. Such clone can be used as one’s responsible representative when the human is not available. Pi-Mind (“Patented Intelligence”) is a technology, which enables “cloning” cognitive skills of humans using adversarial machine learning. In this paper, we present a cyber-physical environment as an adversarial learning ecosystem for cloning image classification skills. The physical component of the environment is provided by the logistic laboratory with camera-surveilla…
The Role of Perceived Social Support as a Contributor to the Successful Transition from Primary to Lower Secondary School
2019
Following approximately 1,800 Finnish children, this longitudinal study examined the associations between students’ perceived social support (teacher-student relationships, family support, and peer support), behavioral engagement, cynicism towards school, and academic achievement during the transition from primary to lower secondary school. After controlling for parental educational level and cynicism before the school transition, the results showed that the more students experienced pre-transition peer support, the less they reported post-transition cynicism. Furthermore, pre-transition peer support contributed to students’ increased academic achievement and behavioral engagement after the…
Data-driven Interactive Multiobjective Optimization : Challenges and a Generic Multi-agent Architecture
2020
In many decision making problems, a decision maker needs computer support in finding a good compromise between multiple conflicting objectives that need to be optimized simultaneously. Interactive multiobjective optimization methods have a lot of potential for solving such problems. However, the growth of complexity in problem formulations and the abundance of data bring new challenges to be addressed by decision makers and method developers. On the other hand, advances in the field of artificial intelligence provide opportunities in this respect. We identify challenges and propose directions of addressing them in interactive multiobjective optimization methods with the help of multiple int…
Interactive evolutionary multiobjective optimization with modular physical user interface
2022
© 2022 Copyright held by the owner/author(s). Incorporating the preferences of a domain expert, a decision-maker (DM), in solving multiobjective optimization problems increased in popularity in recent years. The DM can choose to use different types of preferences depending on his/her comfort, requirements, or the problem being solved. Most papers, where preference-based and interactive algorithms have been proposed, do not pay attention to the user interfaces and input devices. If they do, they use character or graphics-based preference input methods. We propose the option of using a physical or tactile input device that gives the DM a better sense of control over providing his/her preferen…
Dialogue as a Response to the Psychiatrization of Society? Potentials of the Open Dialogue Approach
2021
In recent decades, the use of psychosocial and psychiatric care systems has increased worldwide. A recent article proposed the concept of psychiatrization as an explanatory framework, describing multiple processes responsible for the spread of psychiatric concepts and forms of treatment. This article aims to explore the potentials of the Open Dialogue (OD) approach for engaging in less psychiatrizing forms of psychosocial support. While OD may not be an all-encompassing solution to de-psychiatrization, this paper refers to previous research showing that OD has the potential to 1) limit the use of neuroleptics, 2), reduce the incidences of mental health problems and 3) decrease the use of ps…
Poikkeavuuksien havaitseminen WWW-palvelinlokidatasta
2011
Nykyajan web-palvelut ovat dynaamisia ja avoimia. Tämä antaa suurelle joukolle käyttäjiä mahdollisuuden päästä käsiksi palveluun ja sen sisältämään tietoon. Samalla avautuu uusia mahdollisuuksia toteuttaa hyökkäys. Tietoturvan pitäminen riittävällä tasolla on kilpailua aikaa vastaan. Poikkeavuuksien havaitsemisjärjestelmillä pystytään kuitenkin havaitsemaan ennestään tuntemattomat hyökkäykset ja muu epänormaali toiminta ja siten pitämään tietoturva hyvällä tasolla. Tutkimuksessa sovellettiin n-grammianalyysia, tukivektorikonetta ja diffuusiokarttoja esikäsitellyn verkkodatan analysointiin. Kaikilla menetelmillä saatiin lupaavia tuloksia, mutta reaaliaikainen järjestelmä vaatii vielä jatkoke…
Oppimisen teknologiat osana oppimisen esteitä kohtaavien peruskoululaisten elämää
2017
Tieto- ja viestintäteknologia on merkittävä osa jokapäiväistä elämäämme. Nämä teknologiat ovat löytäneet tiensä kouluihin myös Suomessa, ja erilaisia oppimisen teknologioita onkin otettu ahkerasti käyttöön ympäri maata. Teknologian integroiminen osaksi opetusta ei kuitenkaan aina suju täysin ongelmitta. Laitteiden käytössä saattaa ilmetä ongelmia, ja vaikka infrastruktuuri teknologian käytölle olisikin olemassa, ovat verkkoyhteydet paikoitellen epävakaita. Näiden ongelmien kanssa painivat sekä opettajat että oppilaat. Tämän tutkielman tarkoituksena on tutkia oppimisen teknologioiden vaikutuksia erityisesti oppimisen esteitä kohtaavien oppilaiden oppimiseen. Oppimisen esteitä, kuten erilaisi…

The 21st Century Reforms (Re)Shaping the Education Policy of Inclusive and Special Education in Finland
2021
In recent decades, an essential global aim of the reforms of special education has been the promotion of inclusive education. This article discusses the implementation of reforms with a focus on tiered support systems in the context of Finnish comprehensive school education. Based on earlier literature, legislation, and administrative documents, we provide a background for Finnish education policy and special education reforms. The focus of this article is on the description of parallel reforms targeting the re-structuring of the systems around support for students and funding of education in the 2010s. We discuss the processes leading to these reforms and the reforms themselves. In additio…
