Diversity in Ensemble Feature Selection
2003
Ensembles of learnt models constitute one of the main current directions in machine learning and data mining. Ensembles allow us to achieve higher accuracy, which is often not achievable with single models. It was shown theoretically and experimentally that in order for an ensemble to be effective, it should consist of high-accuracy base classifiers that should have high diversity in their predictions. One technique, which proved to be effective for constructing an ensemble of accurate and diverse base classifiers, is to use different feature subsets, or so-called ensemble feature selection. Many ensemble feature selection strategies incorporate diversity as a component of the fitness funct…
2030 for the EU: Real steps of change? A short commentary on Biodiversity Strategy and Farm to Fork
2020
A short commentary on the EU 2030 Biodiversity Strategy and the Farm to Fork Strategy. The Covid-19 pandemic adds other similarly contradictory stances: it is an occasion to change the world for the better, but it also forces us to focus on the here and now to save lives and jobs. The Strategy, whose subtitle is Bringing nature back into our lives, seems to speak to people in lock-down, building on their sense of suffocation from strict indoor living and on the beautiful and nourishing memories of moments spent in nature. However, the Strategy also, and mostly, speaks to industries and entrepreneurs who are projected to the post-Covid time to bring business back into their lives. Regardless…
Social Dimension and Inequality Problems in the European Union
2017
The purpose of this paper is to introduce evaluation of social development convergence between EU-28 member states in the context of the EU cohesion policy. The main tasks of this study is to assess social dimension and inequalities problems in the European states by applying theory of convergence for real estimations social situations in EU countries. Additionally the development challenges are discussed for improvement of the socio-economic well-being of EU states and to avoid social disparities. The research methodology is based on the convergence theory, on the EU strategies, European Commission legitimate documents application, on the calculations and socio-economic forecasts analysis …
Long-term ecology of investors in a financial market
2018
AbstractThe cornerstone of modern finance is the efficient market hypothesis. Under this hypothesis all information available about a financial asset is immediately incorporated into its price dynamics by fully rational investors. In contrast to this hypothesis many studies have pointed out behavioral biases in investors. Recently it has become possible to access databases that track the trading decisions of investors. Studies of such databases have shown that investors acting in a financial market are highly heterogeneous among them, and that heterogeneity is a common characteristic of many financial markets. The article describes an empirical study of the daily trading decisions of all Fi…
Faunal invasions as a source of morphological constraints and innovations? The diversification of the early Cardioceratidae (Ammonoidea; Middle Juras…
2005
Abstract Multivariate analysis of shell characters and quantification of morphological diversity (morphospace occupation and disparity) are used here to investigate the modes of morphological diversification of ammonites. We define five events in early cardioceratid history that connect geographical changes causing emigration or immigration phases with biodiversity dynamics: (1) the initial colonization of the Arctic Basin by the Cardioceratidae at the end of the Bajocian, Middle Jurassic; (2) the first appearance of the Kosmoceratidae clade in the Boreal Realm during the Bathonian; (3) the ensuing expansion phase of this clade in the Boreal Realm; (4) the first phase of migration of the Ca…
Education and Employment: A Survey of French Research
1981
There is little doubt that at the end of the 1 960s, French research into the education-income relationship as a means of analysing also the relationship between training and employment remained unadvanced by comparison with work of this kind undertaken in English-speaking countries. Mainly attributable to a lack of appropriate data, this weakness incited the public authorities to develop, at the beginning of the 1970s, the gathering of such information, first on the cost of education, and then on wage levels. Thenceforth, the education-income relationship was subject to close analysis, while studies were carried out to elucidate the influence of variables other than education itself. Indee…
University Rankings: The Many Sides of the Debate
2014
Abstract Within the context of bourgeoning institutions that rank higher education institutions, this paper examines the merits and demerits of university rankings and diverse ranking methodologies. It explores and presents recent developments and diversification of international rankings and highlights their general trend towards more broadly balanced and multidimensional criteria. The paper concludes that like any other complex endeavour, rankings have their pros and cons but the latter does not justify their abandonment. What is required is public education that builds a discerning user who can optimally gain from the use of rankings while avoiding their pitfalls. The original version of…
Rethinking the Finance of Post-Compulsory Education
2010
Throughout the world, the finance of education is in serious crisis. The crisis of educational finance is not limited to the problem of meeting the obligations of societies to provide some minimum amount of compulsory education for their students. This minimum does not assure the preparation of an appropriately trained labour force in a world that is increasingly technicological and in which a competitive economy requires the remplacement of traditional production processes with others based on sophisticated labour and capital. The rapid growth of post-compulsory systems of education is no longer a luxury, but a necessity for industrialization and economic development.
Regional Tourism Development in Romania – Consistency with Policies and Strategies Developed at EU Level
2013
Abstract The national tourism development master plan for the period 2007-2026 focuses on tourism resources of the regions. The regional tourism development strategy should have the opportunities and threats that are found in every county of the region as guide marks. Their identification leads to facilitate the implementation of tourism development strategy, the opportunity maximum use being the revival and growth ramp of tourist activities, preventing threats ensure the proper functioning of the implementation process. In this paper we analyzed a series of indicators of tourist movement in the eight development regions of Romania.
The Analysis of the Relationship between the Level of the Public Expenditure for Investments and de Degree of Development of the Society in Romania
2013
Abstract Public expenditure for development have a decisive role in Romania in the economic recovery of the country, in a first step, but at the same time taking into account the EU's objectives. Romania during 2000-2010 had the largest public investment expenditures across European countries as a share of GDP, and in 2011 was ranked second after Poland. But while the share of GDP allocated to public investment in Romania is above the average of EU countries, in the economy these expenditures have been seen too little. Looking at Lisbon Index score, which tracks the performance of member countries to achieve the objectives of the current Lisbon strategy, one can notice that Romania is on th…
