Recent Submissions
-
(Institute of Electrical and Electronics Engineers (IEEE), 2019)We present a modification of conjugate beamforming for the forward link of cell-free massive MIMO networks. This modification eliminates the self-interference and yields a performance that, without forward pilots, closely ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2019)We consider the number of users associating with each base station in a cellular network. Extending and unifying the characterizations for certain settings available in the literature, we derive a result that is asymptotic ...
-
(ACM Association for Computer Machinery, 2018)The ACM RecSys Challenge 2018 focuses on music recommendation in the context of automatic playlist continuation. In this paper, we describe our approach to the problem and the final hybrid system that was submitted to the ...
-
(International Speech Communication Association (ISCA), 2018)In this paper, we tackle the singing voice phoneme segmentation problem in the singing training scenario by using language independent information – onset and prior coarse duration. We propose a two-step method. In the ...
-
(Frontiers, 2016)Expert musicians introduce expression in their performances by manipulating sound properties such as timing, energy, pitch, and timbre. Here, we present a data driven computational approach to induce expressive performance ...
-
(ACM Association for Computer Machinery, 2017)Though musicians tend to agree on the importance of practicing expressivity in performance, not many tools and techniques are available for the task. A machine learning model is proposed for predicting bowing velocity ...
-
(2019)We analyze the impact of reserve requirements on the supply of credit to the real sector. For identification, we exploit a tightening of reserve requirements in Uruguay during a global capital in ows boom, where the change ...
-
(2019)We study negative interest rate policy (NIRP) exploiting ECB’s NIRP introduction and administrative data from Italy, severely hit by the Eurozone crisis. NIRP has expansionary effects on credit supply—and hence the real ...
-
(2019)We show that local central bank policies attenuate global financial cycle (GFC)’s spillovers. For identification, we exploit GFC shocks and Brazilian interventions in FX derivatives using three matched administrative ...
-
(2018)We analyze a small, new credit facility of a Spanish state-owned-bank during the crisis, using its continuous credit scoring system, firm-level scores, and credit register data. Compared to privately-owned banks, the ...
-
(2017)We analyze the impact of balance-sheet strength on credit availability. Bank balance sheets are weak in crisis times, but so are those of firms, and credit demand is then also weak. For identification, we exploit an ...
-
(2018)We analyze how international financial integration is affected by the recent financial and sovereign crises, exploiting euro-area proprietary interbank data, crisis and monetary shocks, and loan terms to the same borrower ...
-
(2019)Banking crises are recurrent phenomena, often induced by excessive bank risk-taking, which may be due to behavioral reasons (over-optimistic banks neglecting risks) and to agency problems between bank shareholders with ...
-
(2018)We investigate the connections between bank capital regulation and the prevalence of lightly regulated nonbanks (shadow banks) in the U.S. corporate loan market. For identification, we exploit a supervisory credit register ...
-
(2019)Do financial crises radicalize voters? We analyze a canonical case – Germany during the Great Depression. After a severe banking crisis in 1931, caused by foreign shocks and political inaction, radical voting increased ...
-
(SCITEPRESS, 2019)Image inpainting is the task of filling-in missing regions of a damaged or incomplete image. In this work we tackle this problem not only by using the available visual data but also by incorporating image semantics through ...
-
(Public Library of Science (PLoS), 2015)Cortical networks, in-vitro as well as in-vivo, can spontaneously generate a variety of collective dynamical events such as network spikes, UP and DOWN states, global oscillations, and avalanches. Though each of them has ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2018)This paper addresses the performance improvement that structured pilot assignment policies can bring about, relative to a random pilot assignment, in cell-free massive MIMO wireless networks. It is shown that structured ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2018)We present a measurement-driven algorithm to map the large-scale channel losses observed between a cellular base station and any point in its coverage area. The algorithm is on-line, meaning that it operates on continuously ...
