Measuring information dynamics in swarms
No full textWe propose a novel, information theoretic characterization of dynamics within swarms, through explicitly measuring the extent of collective communications and tracing collectivememory. These elements of distributed computation provide complementary views into the capacity for swarm coherence and reorganization. The approach deals with both global and local information dynamics ultimately discovering diverse ways in which an individual’s location within the group is related to its information processing role.22 page(s

Hyperauthorship in Mikhail Bakhtin: The Primary Author and Conceptual Personae
No full textThis article explores the phemenon of hyperauthorship in intellectual writing: a primary author (hyperauthor) creates a number of secondary authors (hypoauthors), and develops possible conceptual systems on their behalf. The case under consideration is Mikhail Bakhtin and his complex relationship with his friends Pavel Medvedev and Valentin Voloshinov, members of the so called "Bakhtin's circle" (in the 1920s) who are credited with authorship of several books which may have been actually written by Bakhtin himself. Still unclear from biographical and historical perspectives, this problem of authentic attribution of Medvedev's and Voloshinov's texts can be clarified in the theoretical framework of "hyperauthorship" and "possibilistic thinking." This article applies Bakhtin's own theory of the "primary author immersed in silence," as well as Deleuze and Guattari's notion of "conceptual personae," to explain this case of "shared," or "transferred" authorship. The figures of Voloshinov and Medvedev, though historically real, may be viewed as Bakhtin's projections of "ideal," or "utopian" Marxism in linguistics and literary theory
On the cross-disciplinary nature of guided self-organisation
No full textSelf-organisation is pervasive: neuronal ensembles self-organise into complex spatio-temporal spike patterns which facilitate synaptic plasticity and long-term consolidation of information; large-scale natural or social systems, as diverse as forest fires, landslides, or epidemics, produce spontaneous scale-invariant behaviour; robotic modules self-organise into coordinated motion patterns; individuals within a swarm achieve collective coherence out of isolated actions; and so on. Selforganisation is also valuable: the resultant increase in an internal organisation brings benefits to the (collective) organism, be it a learning brain, a co-evolving ecosystem, an adapting modular robot, or a re-configuring swarm. These benefits are typically realised in increased resilience to external disturbances, adaptivity to novel tasks, and scalability with respect to new challenges. However, self-organisation is difficult to engineer on demand: the intricate fabric of interactions within a self-organising system cannot follow a simple-minded blueprint and resists crude interventions.13 page(s
What are the implications of Curriculum Learning strategy on IRL methods?: Investigating Inverse Reinforcement Learning from Human Behavior
No full textInverse Reinforcement Learning (IRL) is a subfield of Reinforcement Learning (RL) that focuses on recovering the reward function using expert demonstrations. In the field of IRL, Adversarial IRL (AIRL) is a promising algorithm that is postulated to recover non-linear rewards in environments with unknown dynamics. This study investigates the potential benefits of applying the Curriculum Learning (CL) strategy to the AIRL algorithm. For our experiments, we use a randomized partially observable Markov decision process in the form of a grid-world-like environment. Using only expert demonstrations obtained with an RL algorithm under the true reward function, we train AIRL in a variety of configurations and identify an effective curriculum. Our results show, that a well-constructed curriculum can enhance the performance of AIRL twofold in both key aspects: the speed of convergence and the efficiency of using expert demonstrations. We thus conclude that CL can be a useful addition to an AIRL-based solution.

A Framework for the local information dynamics of distributed computation in complex systems
No full textThe nature of distributed computation has long been a topic of interest in complex systems science, physics, artificial life and bioinformatics. In particular, emergent complex behavior has often been described from the perspective of computation within the system (Mitchell 1998b,a) and has been postulated to be associated with the capability to support universal computation (Langton 1990; Wolfram 1984c; Casti 1991).44 page(s
The importance of marketing in the music industry
No full textAuthor: Ekimov Mikhail
Title of the Publication: The importance of marketing in the music industry
Degree Title: Bachelor of International Business
Keywords: Marketing, music industry, metal music, Behemoth
This thesis is a study, analysis, and development of marketing campaigns for aspiring musicians
The thesis will begin with a theory that includes the basic concepts, features, and concepts of marketing in the music industry. Next, the stages of the marketing campaigns of the successful band Behemoth will be reviewed and analyzed. Based on this analysis, it will be possible to under-stand exactly what actions made the band Behemoth successful. Next, a marketing strategy will be created for a budding and not very popular band, The Nomad. For this purpose, the musician of this band will be interviewed, on the basis of which the main marketing problems of the band and the direction of new strategies will be revealed. At the end of the work the main marketing cam-paigns for the development of the marketing strategy of the band at this stage will be made and their effectiveness will be evaluated.
The main goal: to develop marketing strategies for aspiring music groups in the music industry.
The main tasks: Learn the concepts, principles, and functions of marketing in the music industry and how to use them to create own marketing strategies

No full textAbstract We consider a hierarchical multicellular sensing and communication network, embedded in an ageless aerospace vehicle, that is expected to detect and react to multiple impacts and damage over a wide range of impact energies. In particular, we investigate self-organization of impact boundaries enclosing critically damaged areas, and impact networks connecting remote cells that have detected noncritical impacts. Each level of the hierarchy is shown to have distinct higher-order emergent properties, desirable in self-monitoring and self-repairing vehicles. In addition, cells and communication messages are shown to need memory (hysteresis) in order to retain desirable emergent behavior within and between various hierarchical levels. Spatiotemporal robustness of self-organizing hierarchies is quantitatively measured with graph-theoretic and information-theoretic techniques, such as the Shannon entropy. This allows us to clearly identify phase transitions separatin
Muriel Spark as auto-biographer in <i>Curriculum</i> <i>Vitae</i>
No full textExamining Muriel Spark's main aims as an auto-biographer in her work Curriculum Vitae brings important resources in the exploration of the genre of autobiographical writing. This with the theoretical engagement, allows consideration of the critical issues surrounding the roles of author and reader in the construction of the literary self. Spark demands the reader participate in the constructon of textual meaning; overturning the conventions of autobiography, satirising its claims to omniscience and highlighting the impossibility of an authentic voice with regard to the self
