Probabilistic cross-validation estimators for Gaussian process regression

2018

Gaussian Processes (GPs) are state-of-the-art tools for regression. Inference of GP hyperparameters is typically done by maximizing the marginal log-likelihood (ML). If the data truly follows the GP model, using the ML approach is optimal and computationally efficient. Unfortunately very often this is not case and suboptimal results are obtained in terms of prediction error. Alternative procedures such as cross-validation (CV) schemes are often employed instead, but they usually incur in high computational costs. We propose a probabilistic version of CV (PCV) based on two different model pieces in order to reduce the dependence on a specific model choice. PCV presents the benefits from both…

Innovations and Challenges: Conceptualizing CLIL Practice

2018

The continued emergence of content and language integrated learning (CLIL) is linked to how it creates, adopts, and leads to the design of innovative didactic processes. In systems, theory emergenc...

“Sealfie”, “Phoque you” and “Animism”: The Canadian Inuit Answer to the United-States Anti-sealing Activism

2018

A corpus made by online Canadian newspaper articles, coming from the archives of CBC News, Vice Canada and Huffington Post Canada, and related multimedia contents such us audio interviews, videos and especially links to images and comments shared on Twitter, allows us to reconstruct the debate on the seal hunt that involved Canadian media in 2014. In specific, we propose an interpretation of the pro-sealing discourse by Canadian Inuit and Newfoundlanders as an ironic and incisive answer to the serious United States animal rights activists discourse, explaining how these two different points of view on animals come from a different experience of the environment and a different conception of …

Effetto del trattamento con 1-meticiclopropene su frutti di mango (Mangifera indica L.) della cul ti var Kei tt, conservati a temperatura ambiente

2016

Il Mango (Mangifera indica L.) è un frutto climaterico sensibile alle basse temperature e con una vita post-raccolta relativemente breve. L’obiettivo della ricerca è stato quello di valutare l’effetto dell’ 1-metilciclopropene (1-MCP), applicato a temperature ambiente, sulla conservazione di frutti di mango della cv Keitt. I frutti di Keitt, cultivar a maturazione tardiva, sono stati raccolti, presso un’azienda commerciale, sita a Furiano, in provincia di Messina (38°3' N, 14°33' E; 5 m s.l.m.). Immediatamente dopo la raccolta, sui frutti sono state effettuate le analisi chimico-fisiche: peso, consistenza, contenuto in solidi solubili, acidità titola- bile, colore, ecc. I frutti sono sta…

A posteriori error majorants of the modeling errors for elliptic homogenization problems

2013

In this paper, we derive new two-sided a posteriori estimates of the modeling errors for linear elliptic boundary value problems with periodic coefficients solved by homogenization. Our approach is based on the concept of functional a posteriori error estimation. The estimates are obtained for the energy norm and use solely the global flux of the non-oscillatory solution of the homogenized model and solution of a boundary value problem on the cell of periodicity.

A posteriori modelling-discretization error estimate for elliptic problems with L ∞-Coefficients

2017

We consider elliptic problems with complicated, discontinuous diffusion tensor A0. One of the standard approaches to numerically treat such problems is to simplify the coefficient by some approximation, say Aϵ, and to use standard finite elements. In [19] a combined modelling-discretization strategy has been proposed which estimates the discretization and modelling errors by a posteriori estimates of functional type. This strategy allows to balance these two errors in a problem adapted way. However, the estimate of the modelling error was derived under the assumption that the difference A0 - Aϵ becomes small with respect to the L∞-norm. This implies in particular that interfaces/discontinui…

Estudio ex post-facto del estrés a largo plazo en una muestra de personas adoptadas

2016

In this work we study the impact of relinquishment and the adoption process in posttraumatic symptoms in a group of 55 adults that were adopted as children before 1970. The effects of institutionalization, maltreatment, traumatic revelation of the adopted status and stressful life events have also been studied. No significant differences were found between institutionalized and non-institutionalized adoptees in posttraumatic symptomatology. However, adoptees who suffered maltreatment, traumatic revelation and high level of stressful life events scored significantly higher in intrusion and arousal than those adoptees non-maltreated, without traumatic revelation and with low level of stressfu…

Atlantin ylityksiä : amerikkalaisen kirjallisuuden- ja kulttuurintutkimuksen navigointia 1965-1995

2011

Teoriat muuttuvat paitsi aikaa myös paikkaa myöten. Kirjassa tutkitaan eurooppalaisen, varsinkin ranskalaisen teorian Atlantin ylityksiä. Millaisiksi eräät keskeiset teoriaotteet muotoutuivat yhdysvaltalaisessa yliopistomaailmassa ja kohdatessaan uudet poliittiset ja kulttuuriset haasteet? Tämän muotoutumisen vaikutukset näkyvät vuorostaan muualla. Ajanjakso on 1965–1995. "Korkean teorian" nousu liittyi kielelliseen käänteeseen ja perustojen horjumiseen, ja sen erilaisten muotojen ja myös vastustamisen tarkastelu ulottuu kielen merkityksiä hajottavasta retorisuudesta valtarakenteiden marxilaiseen analyysiin, afrikkalaisamerikkalaiseen feminismiin ja "orientalismin" symboliseen tuottamiseen …

Valmistalon evoluutio suomalaisen puutaloteollisuuden mainoskuvastoissa 1980-2000-luvuilla

2013

Tutkielman aiheena on suomalaisten puurakenteisten valmistalojen arkkitehtuuri ja kehitys 1980-luvulta 2000-luvulle. Koska aihetta ei ole tutkittu, tutkielman tavoitteena on saada ilmiöstä kokonaiskuva. Valmistalot ovat näkyvä osa suomalaista rakennettua ympäristöä, sillä teollisesti tuotetuista omakotitaloista tuli tutkittavana ajanjaksona suosituin omakotirakentamisen muoto. Tutkimusaineistoon kuuluu 45 talokuvastoa puutaloteollisuuden eri toimijoilta sekä kolme toimitettua talo-opasta. Tutkielma edustaa laadullista tutkimusta ja pyrkii ilmiön kokonaisvaltaiseen ymmärtämiseen. Analyysi tähtää valmistalojen julkisivuarkkitehtuurin piirteiden tunnistavaan ja nimeävään tarkasteluun sekä vaik…
