Expanding the Active Inference Landscape: More Intrinsic Motivations in the Perception-Action Loop
2018
Active inference is an ambitious theory that treats perception, inference and action selection of autonomous agents under the heading of a single principle. It suggests biologically plausible explanations for many cognitive phenomena, including consciousness. In active inference, action selection is driven by an objective function that evaluates possible future actions with respect to current, inferred beliefs about the world. Active inference at its core is independent from extrinsic rewards, resulting in a high level of robustness across e.g.\ different environments or agent morphologies. In the literature, paradigms that share this independence have been summarised under the notion of in…
Fractional Spectral Moments for Digital Simulation of Multivariate Wind Velocity Fields
2012
In this paper, a method for the digital simulation of wind velocity fields by Fractional Spectral Moment function is proposed. It is shown that by constructing a digital filter whose coefficients are the fractional spectral moments, it is possible to simulate samples of the target process as superposition of Riesz fractional derivatives of a Gaussian white noise processes. The key of this simulation technique is the generalized Taylor expansion proposed by the authors. The method is extended to multivariate processes and practical issues on the implementation of the method are reported.
Audio-video people recognition system for an intelligent environment
2011
In this paper an audio-video system for intelligent environments with the capability to recognize people is presented. Users are tracked inside the environment and their positions and activities can be logged. Users identities are assessed through a multimodal approach by detecting and recognizing voices and faces through the different cameras and microphones installed in the environment. This approach has been chosen in order to create a flexible and cheap but reliable system, implemented using consumer electronics. Voice features are extracted by a short time cepstrum analysis, and face features are extracted using the eigenfaces technique. The recognition task is solved using the same Su…
On Pareto optima, the Fermat-Weber problem, and polyhedral gauges
1990
This paper deals with multiobjective programming in which the objective functions are nonsymmetric distances (derived from different gauges) to the points of a fixed finite subset of ℝn. It emphasizes the case in which the gauges are polyhedral. In this framework the following result is known: if the gauges are polyhedral, then each Pareto optimum is the solution to a Fermat—Weber problem with strictly positive coefficients. We give a new proof of this result, and we show that it is useful in finding the whole set of efficient points of a location problem with polyhedral gauges. Also, we characterize polyhedral gauges in terms of a property of their subdifferential.
Scattering theory for a class of fermionic Pauli–Fierz models
2004
Abstract The scattering theory for a class of fermionic Pauli–Fierz models is considered. We give a proof of the asymptotic completeness of the dynamics in the case of massive fermions. The result applied to the Hamiltonian of a quantized spin- 1 2 Dirac particle interacting with an external field through a cutoff Yukawa interaction and to the Hamiltonian of a system of finitely many confined particles coupled to a fermionic field with a quadratic interaction.
Boundary/Field Variational Principles for the Elastic Plastic Rate Problem
1991
An elastic-plastic continuous solid body under quasi-statically variable external actions is herein addressed in the hypoteses of rate-independent material model with dual internal variables and of infinitesimal displacements and strains. The related analysis problem for assigned rate actions is first formulated through a boundary/field integral equation approach, then is shown to be characterized by two variational principles, one of which is a stationarity theorem, the other a min-max one.
OS ECJ-TF 1/2020 on the General Court Decisions of 24 September 2019 in The Netherlands v. Commission (Starbucks) (Joined Cases C-760/15 and T-636/16…
2020
This article provides a comprehensive exame of the decisions of the EU General Court in the cases The Netherlands v. Commission (Starbucks) (Joined Cases C-760/15 and T-636/16) (hereinafter Starbucks NL) and Luxembourg v. Commission (Fiat Finance and Trade) (Joined Cases T-755/15 and T-759/15) (hereinafter Fiat), decided on 24 September 2019. These are the first in a series of expected decisions concerning the legality of the European Commission's decisions considering certain transfer pricing rulings granted by Member States to multinational enterprises (hereinafter MNEs) to constitute State aid. The GC reached different verdicts in the two cases. Whereas in Starbucks NL it annulled the Co…
On the Review of structure and effectiveness of the IFRS Foundation : the EAAs Financial Reporting Standards Committees view
2016
AbstractIn July 2015 the International Financial Reporting Standards (IFRS) Foundation launched its third five year review of its structure and effectiveness of the organisation. In a public call, the Trustees solicited stakeholders’ input on the relevance of IFRS Standards with respect to broadening the IFRS scope and to the impact of new technology, on the consistent application of IFRS and on the governance and funding of the International Accounting Standards Board and the IFRS Foundation. The European Accounting Association (EAA)’s Financial Reporting Standards Committee responded to this request for views by submitting a comment letter based on research-informed opinions. This article…
‘Classical’ doping, financial doping and beyond: UEFA’s financial fair play as a policy of anti-doping
2014
Against the backdrop of an increasing use of the term ‘doping’ in circumstances other than the classical understanding, this theoretic article provides a new and comprehensive inter-disciplinary reflection of the doping concept. The aim is to elaborate a broader understanding of doping in relation to socio-economic contexts. Besides addressing the question which structural similarities in general justify the label ‘doping’, a comparison between ‘classical’ doping and the so-called financial doping in European club football is developed. These insights serve as a basis for a consideration, to what extent insights of social-scientific research on drugs in sport may be consulted to analyse soc…
The multiplex structure of interbank networks
2013
The interbank market has a natural multiplex network representation. We employ a unique database of supervisory reports of Italian banks to the Banca d'Italia that includes all bilateral exposures broken down by maturity and by the secured and unsecured nature of the contract. We find that layers have different topological properties and persistence over time. The presence of a link in a layer is not a good predictor of the presence of the same link in other layers. Maximum entropy models reveal different unexpected substructures, such as network motifs, in different layers. Using the total interbank network or focusing on a specific layer as representative of the other layers provides a po…
