Evaluation model for multi-microgrid with autonomous DC energy exchange

Sony CSL

This paper proposes an evaluation model to analyze the impact of microgrid topologies on self‐sufficiency for a given size of batteries and photovoltaic (PV) panels (resources). Three topologies are evaluated for a community of 19 houses: centralized resources (ideal case), stand‐alone resources, and a multi‐microgrid topology with autonomous exchange. Depending on the ratio of PV […]

The dynamics of social interactions in a collective creativity experiment

Sony CSL

The study of the dynamics behind the emergence of novelties and inno- vation is a relatively recent field of study in complex systems, fostered by the abundance of data about the creations and sharing of artworks and about on-line activity in general. Despite this recentness, many works have been able to discover and characterise several […]

Copystree: gaming artificial phylogenies

Sony CSL

The reconstruction of phylogenies of cultural artefacts represents an open problem that mixes theoretical and computational challenges. Existing bench- marks rely on simulated phylogenies, where hypotheses on the underlying evolutionary mechanisms are unavoidable, or in real data phylogenies, for which no true evolutionary history is known. Here we introduce a web-based game, Copystree, where users […]

Maximum entropy models capture melodic styles

Sony CSL

We introduce a Maximum Entropy model able to capture the statistics of melodies in music. The model can be used to generate new melodies that emulate the style of a given musical corpus. Instead of using the n–body interactions of (n−1)–order Markov models, traditionally used in automatic music generation, we use a k-nearest neighbour model […]

Search strategies of Wikipedia readers

Sony CSL

The quest for information is one of the most common activity of human beings. Despite the the impressive progress of search engines, not to miss the needed piece of information could be still very tough, as well as to acquire specific competences and knowledge by shaping and following the proper learning paths. Indeed, the need […]

Significance and popularity in music production

Sony CSL

Creative industries constantly strive for fame and popularity. Though highly desirable, popularity is not the only achievement artistic creations might ever acquire. Leaving a longstanding mark in the global production and influencing future works is an even more important achievement, usually acknowledged by experts and scholars. ‘Significant’ or ‘influential’ works are not always well known […]
