Robustness, Stability, and Fidelity of Explanations for a Deep Skin Cancer Classification Model
2022
Skin cancer is one of the most prevalent of all cancers. Because of its being widespread and externally observable, there is a potential that machine learning models integrated into artificial intelligence systems will allow self-screening and automatic analysis in the future. Especially, the recent success of various deep machine learning models shows promise that, in the future, patients could self-analyse their external signs of skin cancer by uploading pictures of these signs to an artificial intelligence system, which runs such a deep learning model and returns the classification results. However, both patients and dermatologists, who might use such a system to aid their work, need to …
DNA Computing: Concepts for Medical Applications
2022
The branch of informatics that deals with construction and operation of computers built of DNA, is one of the research directions which investigates issues related to the use of DNA as hardware and software. This concept assumes the use of DNA computers due to their biological origin mainly for intelligent, personalized and targeted diagnostics frequently related to therapy. Important elements of this concept are (1) the retrieval of unique DNA sequences using machine learning methods and, based on the results of this process, (2) the construction/design of smart diagnostic biochip projects. The authors of this paper propose a new concept of designing diagnostic biochips, the key elements o…
Context-Aware Visual Exploration of Molecular Datab
2006
Facilitating the visual exploration of scientific data has received increasing attention in the past decade or so. Especially in life science related application areas the amount of available data has grown at a breath taking pace. In this paper we describe an approach that allows for visual inspection of large collections of molecular compounds. In contrast to classical visualizations of such spaces we incorporate a specific focus of analysis, for example the outcome of a biological experiment such as high throughout screening results. The presented method uses this experimental data to select molecular fragments of the underlying molecules that have interesting properties and uses the res…
Computer-supported collaboration in a scripted 3-D game environment
2005
The particular focus of this paper is on scripting collaboration in a 3-D virtual game environment intended to make learning more effective, but also take into account the risk of over-scripting learning. The empirical experiment eScape, which encourages learners to solve problems collaboratively, is also presented. This study attempts to find out whether the features of 3-D games can be used to create meaningful scripted collaborative learning environments. The results indicated that scripting persuaded student teams to enter into collaboration, but the actual processes varied.
Prediction of defects using machine learning techniques in order to improve quality management system – A case study
2021
According to ISO 9000, a quality management system is part of a set of related or interacting elements of an organization that sets policies and objectives, as well as the processes necessary to achieve the quality objectives. Quality is the extent to which a set of intrinsic characteristics of an object meets the requirements. Based on these definitions, the factory, considered in this paper, S.C. APULUM S.A.,decided to implement a quality management system since 1998. Subsequently, the organization’s attention is focus on the continuous improvement of the implemented quality management system. The purpose of this paper is to study the percent of specified defects specific to ceramic produ…
Woven folklore: computers promoting cross-cultural understanding
2004
Multicultural cooperation requires participants to understand the cultural background and identity of all the partners. In this respect, computers provide the cooperation with a new and interesting instrument. A team of students from two schools, one in Tanzania, another in Finland, implemented a multimedia version of an African folklore story. A computer served as a platform for genuine cooperation: the whole team worked on one electronic artefact, despite the geographical distance between the members. The collaborative process helped each participant to clarify his/her own cultural background whilst also becoming acquainted with that of his/her distant partner.
"Välillä mua on melkein itkettäny mennä luennolle" : advanced language learners' experiences with foreign language anxiety
2014
Tutkielman tarkoituksena oli selvittää vieraiden kielten yliopisto-opiskelijoiden kokemuksia kielijännityksestä. Tavoitteena oli tarkastella missä tilanteissa opiskelijat kokevat kielijännitystä, mistä se heiden mielestään johtuu, millaisia vaikutuksia jännityksellä on ja millaisia keinoja opiskelijoilla on pärjätä oman jännityksen kanssa. Tutkimuksessa keskeisessä roolissa ovat opiskelijoiden omat käsitykset ja kokemukset. Kielijännitystä on tutkittu paljon mutta aiempi tutkimus on keskittynyt aloitteleviin kielten opiskelijoihin erityisesti Pohjois-Amerikkalaisessa yliopisto kontekstissa. Aiempi tutkimus on myös ollut pitkälti määrällistä tutkimusta. Tästä syystä tämä laadullinen tutkielm…
At the Crossroads: Challenges of Foreign Language Learning
2017
This book offers a valuable contribution to the discussion on the complexities of L2 learning processes that pose a challenge to learners. Focusing on the cognitive, affective and socio-cultural perspectives, the papers included provide important insights into the individual’s experiences in second language acquisition. This work also addresses social interactions and cultural background, shedding new light on their role in the context in L2 learning processes. It is a valuable resource for anyone interested in understanding the challenges of foreign-language (FL) learning and teaching.
Informe Preliminar Sobre la Encuesta de Prácticas Docentes en Países en Vía de Desarrollo
2013
This paper illustrates a research method appropriate for researchers examining teaching practices and teacher training in poor countries. The method of research described here does not compare with large scale studies in terms of sample size, scientific rigor, and sophisticated statistical analysis. We believe, however, that it can, provide valid information sufficient in accuracy for policy making. Most importantly, we believe, this method offers a feasible way for national researchers to explore why teachers teach as they do in their country. A fundamental assumption is that once in the classroom most teachers learn little more about teaching. In the absence of any systematic feedback or …
