On Representing Concepts in High-dimensional Linear Spaces
2017
Producing a mathematical model of concepts is a very important issue in artificial intelligence, because if such a model were found this, besides being a very interesting result in its own right, would also contribute to the emergence of what we could call the ‘mathematics of thought.’ One of the most interesting attempts made in this direction is P. Gardenfors’ theory of conceptual spaces, a ¨ theory which is mostly presented by its author in an informal way. The main aim of the present article is contributing to Gardenfors’ theory of conceptual spaces ¨ by discussing some of the advantages which derive from the possibility of representing concepts in high-dimensional linear spaces.
A perceptual sound space for auditory displays based on sung-vowel synthesis.
2022
AbstractWhen designing displays for the human senses, perceptual spaces are of great importance to give intuitive access to physical attributes. Similar to how perceptual spaces based on hue, saturation, and lightness were constructed for visual color, research has explored perceptual spaces for sounds of a given timbral family based on timbre, brightness, and pitch. To promote an embodied approach to the design of auditory displays, we introduce the Vowel–Type–Pitch (VTP) space, a cylindrical sound space based on human sung vowels, whose timbres can be synthesized by the composition of acoustic formants and can be categorically labeled. Vowels are arranged along the circular dimension, whi…
Mathematical Patterns and Cognitive Architectures
2014
Mathematical patterns are an important subclass of the class of patterns. The main task of this paper is examining a particular proposal concerning the nature of mathematical patterns and some elements of the cognitive architecture an agent should have to recognize them.
Licenziamento e rideterminazione della sanzione disciplinare nel lavoro pubblico privatizzato
2020
Il contributo, dopo un’analisi della disciplina sanzionatoria del licenziamento invalido nel pubblico impiego, prende in esame il nuovo art. 63, c. 2 bis, del D.lgs. n. 165/2001. La norma, che attribuisce al giudice il potere di rideterminare la sanzione in caso di difetto di proporzionalità, è oggi una peculiarità della disciplina del lavoro pubblico privatizzato. L’Autore ritiene che questa si ponga in controtendenza con le recenti riforme del lavoro in Italia, in quanto recupera importanti spazi alla discrezionalità giudiziale.
Monete e spazi sacri: rinvenimenti monetali dai santuari dell’entroterra siciliano
2016
This paper analyzes the coins finds from the sacred area of the indigenous settlements of the Sicilian hinterland. In particular, these coins have been found in sites called Balate, Polizzello, Raffe, Sabucina and Vassallaggi. As, in most cases, the coins are accompanied by the data of excavation, it is possible to make hypotheses about the function carried out the coins within the sacred spaces. It is well known that the coin finds in sacred areas can not be interpreted only as votive offerings, as are also suitable for other readings that only the examination of the context can decode.
Rappresentazioni e territorio nelle dinamiche del turismo: il caso della Lonely Planet Sicily
2018
L’attuale dibattito sul riordino territoriale del Paese rende nuovamente centrale il concetto di territorio che, da sempre, in una prospettiva geografica pone problemi definitori. Esso può essere, infatti, oggetto di produzioni simboliche e (ri)semantizzazioni in grado di ridefinirlo e di creare specifiche modalità di interazione. A questo proposito, il presente lavoro intende proporre una riflessione su alcune dinamiche di produzione e riproduzione simbolica che interessano il concetto di territorio nel turismo, ambito in cui si può osservare una relazione diretta tra rappresentazione del territorio (intesa anche come narrazione) e possibilità d’azione. In particolare, attraverso il caso s…
Oscurità, sguardo e lettura degli spazi. Sensibilità geografiche nel Notturno di D’Annunzio
2019
Il contributo intende collocarsi in seno al dibattito, propriamente geografico, che indaga il ruolo della percezione nella lettura, in ambito letterario, delle complessità spaziali e del paesaggio. Nel caso di specie, si intende approfondire quanto la dimensione dell’oscurità, elemento saliente della notte, determini, nella poetica di D’Annunzio, specifiche letture dei contesti spaziali di riferimento. In particolare, si intende porre attenzione al Notturno, opera redatta in condizione di cecità. È nella privazione della vista e, dunque, nella contingenza di oscurità assimilabile – come indicato dal titolo – alla notte, che la sensibilità percettiva si acuisce e le letture spaziali, rielabo…
Hombres y espacios. Circulación en la monarquía de España en la primera edad moderna
2021
Since the last decades of the last century, studies on the Spanish monarchy have been enriched by new reflections and interest in the political and social dynamics that until then had been neglected, and thanks to the overcoming of historiographic paradigms linked to national realities. This new approach, which is linked to a dual perspective of local and international dimension, has given great importance to what is considered one of the aspects that characterized the Spanish Monarchy of the modern age: circulation, mobility and the transfer of knowledge. Despite the complex territorial articulation and wide geographical distances, the multiple "spaces" that attended the composition of the…
Tra bisogni individuali e fruizione collettiva. Spazi delle biblioteche e pratiche di lettura in una prospettiva diacronica
2021
Over the centuries, libraries have profoundly transformed their spaces, their physical appearance, their organization, but they have always remained faithful to their dual mission: a) to support lifelong learning and individual creativity, and b) to foster community development, that is, the growth of all social groups and age groups. The evolution of libraries has seen a steady acceleration especially since the mid-19th century, when the industrial processes of book production definitely expanded the availability and accessibility of content for a largest audience. The improved socio-economic conditions were best suited to the birth and development of public libraries, acting as democratic…
A combinatorial algorithm related to the geometry of the moduli space of pointed curves
2002
As pointed out in Arbarello and Cornalba ( J. Alg. Geom. 5 (1996), 705–749), a theorem due to Di Francesco, Itzykson, and Zuber (see Di Francesco, Itzykson, and Zuber, Commun. Math. Phys. 151 (1993), 193–219) should yield new relations among cohomology classes of the moduli space of pointed curves. The coefficients appearing in these new relations can be determined by the algorithm we introduce in this paper.
