Unsupervised Adversarial Depth Estimation using Cycled Generative Networks

While recent deep monocular depth estimation approaches based on supervised regression have achieved remarkable performance, costly ground truth annotations are required during training. To cope with this issue, in this paper we present a novel unsupervised deep learning approach for predicting depth maps and show that the depth estimation task can be effectively tackled within an adversarial learning framework. Specifically, we propose a deep generative network that learns to predict the correspondence field i.e. the disparity map between two image views in a calibrated stereo camera setting. The proposed architecture consists of two generative sub-networks jointly trained with adversarial learning for reconstructing the disparity map and organized in a cycle such as to provide mutual constraints and supervision to each other. Extensive experiments on the publicly available datasets KITTI and Cityscapes demonstrate the effectiveness of the proposed model and competitive results with state of the art methods. The code and trained model are available on https://github.com/andrea-pilzer/unsup-stereo-depthGAN.Comment: To appear in 3DV 2018. Code is available on GitHu

Deliberative Democracy in the EU. Countering Populism with Participation and Debate. CEPS Paperback

Elections are the preferred way to freely transfer power from one term to the next and from one political party or coalition to another. They are an essential element of democracy. But if the process of power transfer is corrupted, democracy risks collapse. Reliance on voters, civil society organisations and neutral observers to fully exercise their freedoms as laid down in international human rights conventions is an integral part of holding democratic elections. Without free, fair and regular elections, liberal democracy is inconceivable. Elections are no guarantee that democracy will take root and hold, however. If the history of political participation in Europe over the past 800 years is anything to go by, successful attempts at gaining voice have been patchy, while leaders’ attempts to silence these voices and consolidate their own power have been almost constant (Blockmans, 2020). Recent developments in certain EU member states have again shown us that democratically elected leaders will try and use majoritarian rule to curb freedoms, overstep the constitutional limits of their powers, protect the interests of their cronies and recycle themselves through seemingly free and fair elections. In their recent book How Democracies Die, two Harvard professors of politics write: “Since the end of the Cold War, most democratic breakdowns have been caused not by generals and soldiers but by elected governments themselves” (Levitsky and Ziblatt, 2018)

Direct Democracy in the EU –The Myth of a Citizens’ Union. CEPS Paperback, November 2018

The European Union has a democracy problem. The polycrisis that has plagued the EU for years has led to a cacophony of voices calling for fundamental change to the integration project. Yet despite the shock of the Brexit referendum and the electoral upsets caused by nativist parties across the continent, few of the plans for EU reform include concrete proposals to address the perennial democratic deficit. This book looks at how the relationship between citizens, the state and EU institutions has changed in a multi-layered Union. As such, it focuses more on polity than on populism, and does not engage deeply with policy or output legitimacy. Building on the notion of increasing social, economic and political interdependence across borders, this book asks whether a sense of solidarity and European identity can be rescued from the bottom up by empowering citizens to ‘take back control’ of their Union. Direct Democracy in the EU: The Myth of a Citizens’ Union is part of the 'Towards a Citizens’ Union' project and is the product of collaboration with 20 renowned think tanks from the European Policy Institutes Network (EPIN). It is the first of three publications that will also cover the state of representative democracy in the EU and the accountability of democratic institutions

BOOK REVIEW: RADU CARP, DUMNEZEU LA BRUXELLES. RELIGIA IN SPATIUL PUBLIC EUROPEAN

The religious phenomenon has always generated intense feelings that have often undermined the scientific analysis and the academic debate. In an European political space dominated by secularism Radu Carp analyses the present and future of religion within the European framework. Religions and churches are now a part of the European public sphere and their actions influence public opinion. Although the reference to God lack from the EU official documents the influence and lobby of religious entities are powerful. Churches must now reinvent themselves in order to become more adapted to the new conditions

La Construction Nationale du Concept Européen dans la Vie Politique et Culturelle de la Roumanie de L’entre-deux-guerres - La Première Moitié des Années 1920. Le Grand Débat. Prémisses Introductives

This paper presents a short synopsis of the development of the European idea in the early 1920. In a time of great transformation the Romanian elites are having themselves a series of debates whether to engage in the construction of a national ideal and of nation-building after the creation of Greater Romania or whether to get involved in the European debate regarding the creation of an European construction. It is a time of great intellectual effervescence that will shape the entire period between the two World Wars
