Testing for public debt sustainability using a time-scale decomposition analysis
2013
In this paper we estimate the response of primary surplus to lagged debt to test for debt sustainability within the 17 EMU countries by using a factor model. The analysis is split into two stages. In the first stage we retrieve the cyclical and long-run components of primary surplus and debt ratios of each EMU country using a wavelet decomposition for each fiscal covariate, based on the Maximal Overlapping Discrete Wavelet Transform. In the second stage, we use Full Information Maximum Likelihood for a factor decomposition of thecross covariance matrix of the wavelet coefficients of primary deficit and debt to GDP ratios in order to measure the short run and the long run reaction of the pri…

There's A Ghost In Every Mirror: The Identity of the Ghost In Hamlet
2009
Tutkielmassani käsittelen William Shakespearean näytelmän Hamlet keskeisen hahmon, Haamun, identiteettiä katolisessa ja protestanttisessa teologiassa eriävän kiirastuliopin kautta avautuvana ristiriitana. Tulkitsen Haamun hahmoa perinteistä skeptisemmästä näkökulmasta, jonka pohjalta pyrin löytämään tekstistä viitteitä siihen, että Haamun identiteetti ei missään vaiheessa ole suoraan johdettavissa siihen perinteiseen tulkintaan, jonka mukaan se olisi Hamletin isä. Pyrin valottamaan jo 1500-luvun lopulla Englannissa vaikuttaneen protestanttisen maailmankuvan valossa teoksen kuvauksia Haamun alkuperästä sekä analysoimaan, millä tavalla sen kanssa tekemisissä olevat henkilöhahmot siihen reago…
Shakespeare in the Extreme: Addiction, Ghosts and (Re)Mediation in Alexander Fodor’s Hamlet
2011
This article is an analysis of Fodor's filmic version of Hamlet as simultaneously reverent and irreverent toward the canonical status of the Bard. It shows how Hamlet is being recycled by being brought into contact with contemporary citational environments, from pop music to drug culture.
A multidimensional hydrodynamic code for structure evolution in cosmology
1996
A cosmological multidimensional hydrodynamic code is described and tested. This code is based on modern high-resolution shock-capturing techniques. It can make use of a linear or a parabolic cell reconstruction as well as an approximate Riemann solver. The code has been specifically designed for cosmological applications. Two tests including shocks have been considered: the first one is a standard shock tube and the second test involves a spherically symmetric shock. Various additional cosmological tests are also presented. In this way, the performance of the code is proved. The usefulness of the code is discussed; in particular, this powerful tool is expected to be useful in order to study…
Inference of Spatio-Temporal Functions over Graphs via Multi-Kernel Kriged Kalman Filtering
2018
Inference of space-time varying signals on graphs emerges naturally in a plethora of network science related applications. A frequently encountered challenge pertains to reconstructing such dynamic processes, given their values over a subset of vertices and time instants. The present paper develops a graph-aware kernel-based kriged Kalman filter that accounts for the spatio-temporal variations, and offers efficient online reconstruction, even for dynamically evolving network topologies. The kernel-based learning framework bypasses the need for statistical information by capitalizing on the smoothness that graph signals exhibit with respect to the underlying graph. To address the challenge o…
Online Topology Identification from Vector Autoregressive Time Series
2019
Causality graphs are routinely estimated in social sciences, natural sciences, and engineering due to their capacity to efficiently represent the spatiotemporal structure of multivariate data sets in a format amenable for human interpretation, forecasting, and anomaly detection. A popular approach to mathematically formalize causality is based on vector autoregressive (VAR) models and constitutes an alternative to the well-known, yet usually intractable, Granger causality. Relying on such a VAR causality notion, this paper develops two algorithms with complementary benefits to track time-varying causality graphs in an online fashion. Their constant complexity per update also renders these a…
From optimization to algorithmic differentiation: a graph detour
2021
This manuscript highlights the work of the author since he was nominated as "Chargé de Recherche" (research scientist) at Centre national de la recherche scientifique (CNRS) in 2015. In particular, the author shows a thematic and chronological evolution of his research interests:- The first part, following his post-doctoral work, is concerned with the development of new algorithms for non-smooth optimization.- The second part is the heart of his research in 2020. It is focused on the analysis of machine learning methods for graph (signal) processing.- Finally, the third and last part, oriented towards the future, is concerned with (automatic or not) differentiation of algorithms for learnin…
