Learning from good examples

1995

The usual information in inductive inference for the purposes of learning an unknown recursive function f is the set of all input /output examples (n,f(n)), n ∈ ℕ. In contrast to this approach we show that it is considerably more powerful to work with finite sets of “good” examples even when these good examples are required to be effectively computable. The influence of the underlying numberings, with respect to which the learning problem has to be solved, to the capabilities of inference from good examples is also investigated. It turns out that nonstandard numberings can be much more powerful than Godel numberings.

Osservazioni su contratti algoritmici e tutela del consumatore nell’economia di piattaforma

2020

Il saggio prende in esame alcune delle tutele predisposte dalla direttiva 2019/2161 del Parlamento e del Consiglio in favore del consumatore, nell’ipotesi in cui quest’ultimo sia assistito, nell’incontro con il professionista, dall’uso di tecnologie computazionali: con una espressione di sintesi, l’Autore si riferisce a questa evenienza con la locuzione “contratti algoritmici”. Tre sono gli aspetti cui si dirige l’attenzione: 1) la specificità dell’economia di piattaforma, luogo privilegiato in cui gli algoritmi orientano le scelte di consumo; 2) gli algoritmi che sono adoperati nell’atto di consumo; 3) l’ottimizzazione dei prezzi tramite profilazione automatizzata, quale caso paradigmatico…

Sequential formula translation

1983

The syntax of an algorithmic language such as ALGOL is conveniently described as a sequence of states indicated by an element called cellar. Transitions are controlled by admissible state- s ymbol pairs which may be represented by a transition matrix. This description of syntax furnishes at the same time an extremely simple rule for translating into machine programs statements in the algorithmic language. Sequential treatment, however, is not feasible in the case of certain optimizing processes such as recursive address calculation.

The Coexistence of Three Species of Daphnia in the Klostersee: iii. The Simulation Model Coda

1991

The population dynamics of three coexisting Daphnia species are described by means of a discrete event simulation model. The model is formulated in the algorithmic language SIMULA which allows very convenient object-oriented programming. Different compartments of a lake are simulated at different levels of integration, each represented by a PROCESS CLASS in SIMULA: The properties of the lake are deposited in a set of meteorological data which were measured in the field. Fish are simulated as a population with properties which are derived from field observations and Daphnia are represented as individuals. The model shows that hypotheses about the stabilizing mechanisms (seasonal change of en…

Paths Coloring Algorithms in Mesh Networks

2003

In this paper, we will consider the problem of coloring directed paths on a mesh network. A natural application of this graph problem is WDM-routing in all-optical networks. Our main result is a simple 4-approximation algorithm for coloring line-column paths on a mesh. We also present sharper results when there is a restriction on the path lengths. Moreover, we show that these results can be extended to toroidal meshes and to line-column or column-line paths.

Ohmic treatment of fresh foods: Effect on textural properties

2013

The aim of this work was to verify the effects of ohmic heating (OH) treatment on texture of fresh solid food (without pre-treatment in brine solutions), subjected to constant electrical field gradient (1100 V/m; 2200 V/m; 3300 V/m). Samples of fresh potatoes, carrots and apples cut into cylinders (d = 30 mm, h = 9.0 mm) underwent OH for 60, 120, 180 and 240 seconds. Texture measurements were performed in a universal testing machine Instron 4301, with a 100 N load cell, using a single-cycle compression test. The raw untreated sample was used as control. Stress–deformation behavior of food samples processed by OH differs appreciably from raw untreated samples for all cooking times. Firmness …

Multi-model ensemble simulations of olive pollen distribution in Europe in 2014: current status and outlook

2017

"Çalışmada 29 yazar bulunmaktadır. Bu yazarlardan sadece Bursa Uludağ Üniversitesi mensuplarının girişleri yapılmıştır” The paper presents the first modelling experiment of the European-scale olive pollen dispersion, analyses the quality of the predictions, and outlines the research needs. A 6-model strong ensemble of Copernicus Atmospheric Monitoring Service (CAMS) was run throughout the olive season of 2014, computing the olive pollen distribution. The simulations have been compared with observations in eight countries, which are members of the European Aeroallergen Network (EAN). Analysis was performed for individual models, the ensemble mean and median, and for a dynamically optimised c…

Structural Reforms in Banking: The Role of Trading

2017

In the wake of the recent financial crisis, significant regulatory actions have been taken aimed at limiting risks emanating from trading in bank business models. Prominent reform proposals are the Volcker Rule in the U.S., the Vickers Report in the UK, and, based on the Liikanen proposal, the Barnier proposal in the EU. A major element of these reforms is to separate "classical" commercial banking activities from securities trading activities, notably from proprietary trading. While the reforms are at different stages of implementation, there is a strong ongoing discussion on what possible economic consequences are to be expected. The goal of this paper is to look at the alternative approa…

Insider Trading and Market Behaviour Around Takeover Announcements in the Spanish Market

2002

As microstructure models assume informational asymmetries among investors, the possibility of insider trading is a sound reason for liquidity suppliers to increase the bid-ask spread. In this way, the tested effect that takeover announcements have on target firm returns becomes a strong motive for trading with insider information. In this paper we firstly investigate whether liquidity suppliers value the possibility of trading with informed agents in this sort of event. We analyse the adverse selection cost from bid-ask spread behaviour around takeover announcements. We find that liquidity suppliers enlarge adverse selection cost suggesting that they value the possibility of facing to insid…
