Comparison of feature importance measures as explanations for classification models
2021
AbstractExplainable artificial intelligence is an emerging research direction helping the user or developer of machine learning models understand why models behave the way they do. The most popular explanation technique is feature importance. However, there are several different approaches how feature importances are being measured, most notably global and local. In this study we compare different feature importance measures using both linear (logistic regression with L1 penalization) and non-linear (random forest) methods and local interpretable model-agnostic explanations on top of them. These methods are applied to two datasets from the medical domain, the openly available breast cancer …
Paroles de chef : modèles communicationnels d’une organisation professionnelle
2016
Dans un restaurant, communiquer correspond à informer la clientèle, dialoguer avec elle, collaborer avec les équipes, et diffuser une image du restaurant, des mets et du chef. La communication apparente du chef de cuisine précise le lien qui existe entre lui et son personnel, lui et les clients, lui et les fournisseurs, et plus rarement entre lui et les médias ou supports de communication. Apportant la communication organisationnelle, formelle et normative, auprès de ses subalternes comme de ses fournisseurs, le chef cuisinier tente de diffuser une communication mi-naturelle afin de parfaire une certaine convivialité, et mi-formelle afin de transmettre ou confirmer son savoir-faire. Il s’ag…
Map-based assessment of older adults’ life space: validity and reliability
2020
Background Map-based tools have recently found their way into health-related research. They can potentially be used to quantify older adults’ life-space. This study aimed to evaluate the validity (vs. GPS) and the test-retest reliability of a map-based life-space assessment (MBA). Methods Life-space of one full week was assessed by GPS and by MBA. MBA was repeated after approximately 3 weeks. Distance-related (mean and maximum distance from home) and area-related (convex hull, standard deviational ellipse) life-space indicators were calculated. Intraclass correlations (MBA vs. GPS and test-retest) were calculated in addition to Bland-Altman analyses (MBA vs. GPS). Results Fifty-eight older …
Psychometric properties of the MOBITEC-GP mobile application for real-life mobility assessment in older adults
2022
Aim of this study was to test the reliability and validity of the life-space measures and walking speed delivered by the MOBITEC-GP app. Participants underwent several supervised walking speed assessments as well as a 1-week life-space assessment during two assessment sessions 9 days apart. Fifty-seven older adults (47.4% male, mean age= 75.3 (±5.9) years) were included in the study. The MOBITEC-GP app showed moderate to excellent test-retest reliability (ICCs between 0.584 and 0.920) and validity (ICCs between 0.468 and 0.950) of walking speed measurements of 50 meters and above and of most 1-week life-space parameters, including life-space area, time spent out-of-home, and action range. T…
Lipas data 10/2021
2021
Tämä aineisto sisältää kaikki Lipas-tietokannan liikuntapaikat ja aineistotiedot 20.10.2021. Data on luokiteltu ja jokaiselle liikuntapaikalle on oma Lipas-ID. Data on tarjolla Esri Shapefile -muodossa (pisteet, reitit ja alueet). This data includes all sport facilities in Lipas database in 20.10.2021 and basic attribute information of the places. The data is classified and each sport facility has its own Lipas id. The data is provided as Esri Shapefiles (points, routes and areas) in Finnish, Swedish and English.
Mapping Digital Discourses of the Capital Region of Finland : Combining Onomastics, CADS, and GIS
2022
This article discusses the three Finnish city names Helsinki, Espoo, and Vantaa, and the urban discourses that surround them. The study reveals patterns of socio-spatial differentiation by examining what meanings people attach to these capital region cities and investigating how these meanings are expressed in online discourses. Using the methodological approach of corpus-assisted onomastics (CAO), this study incorporates onomastics, geographical information systems (GIS), and corpus linguistics. This interdisciplinary research also examines how corpus-assisted discourse studies (CADS) and GIS can be combined to reveal and visualize the contextual information and discursive patterns of topo…

Lipas-aineistot
2021
Lipas on valtakunnallinen paikkatietokanta liikuntapaikoista, ulkoilureiteistä ja virkistysalueista. Lipas-tietokantaan kerätään tiedot Suomen julkisista, erityisesti kuntien omistamista liikuntapaikoista. Myös yksityisten yritysten ja yhdistysten hallinnoimia paikkoja löytyy tietokannasta. Tiedon tuottajina toimivat kuntien liikuntatoimen asiantuntijat yhteistyössä kunnan muiden toimialojen kanssa sekä virkistysalueyhdistykset ja lajiliitot. Lisäksi Lipas-projektissa tehdään aineiston kattavuuden ja laadun seurantaa ja tietojen täydennystä. Hankkeesta löytyy lisätietoa lipas.fi ja lipasinfo.fi. Hankkeesta julkaistaan säännöllisin väliajoin otoksia. Aineisto on ladattavissa myös hankkeen om…

A fuzzy-based tool for modelization and analysis of the vulnerability of aquifers: a case study
2005
Abstract A fuzzy-based tool, called FUZZY-SRA (Fuzzy Spatial Reliability Analysis), is used for realizing a more “reliable” study of the values of the final parameters concerning the vulnerability of aquifers located in the territory of Cava de' Tirreni, city in the district of Salerno (Italy). The SINTACS method is adopted for evaluating the involved parameters and these evaluations are modelled from attributes represented from triangular fuzzy numbers which supply the overall final information if combined with suitable algebraic operations. The tool FUZZY-SRA is implemented inside a GIS (Geographical Information Systems) software.
