Homo Entropicus, the emotional agent and societies of Neural Networks
Felippe Alves, Nestor Caticha
A neural network with a learning algorithm optimized by information theory entropic dynamics is used to build an agent dubbed Homo Entropicus. The algorithm can be described at a m…
Frustration, glassy behavior and dynamical annealing in societies of Neural Networks
Felippe Alves, Nestor Caticha
We study maximum entropy mechanisms of information exchange between agents modeled by neural networks and the macroscopic states of a society of such agents in a few situations. Ma…
Phase transition from egalitarian to hierarchical societies driven by competition between cognitive and social constraints
Nestor Caticha, Rafael Calsaverini, Renato Vicente
Empirical evidence suggests that social structure may have changed from hierarchical to egalitarian and back along the evolutionary line of humans. We model a society subject to co…
For whom will the Bayesian agents vote?
Nestor Caticha, Jonatas Cesar, Renato Vicente
Within an agent-based model where moral classifications are socially learned, we ask if a population of agents behaves in a way that may be compared with conservative or liberal po…
Moral foundations in an interacting neural networks society
Renato Vicente, Alex Susemihl, João Pedro Jericó +1
The moral foundations theory supports that people, across cultures, tend to consider a small number of dimensions when classifying issues on a moral basis. The data also show that…
Agent-based Social Psychology: from Neurocognitive Processes to Social Data
Nestor Caticha, Renato Vicente
Moral Foundation Theory states that groups of different observers may rely on partially dissimilar sets of moral foundations, thereby reaching different moral valuations. The use o…
Opinion Dynamics of Learning Agents: Does Seeking Consensus Lead to Disagreement?
Renato Vicente, Andre C. R. Martins, Nestor Caticha
We study opinion dynamics in a population of interacting adaptive agents voting on a set of complex multidimensional issues. We consider agents which can classify issues into for o…
Long Term Economic Relationships From Cointegration Maps
Renato Vicente, Carlos de B. Pereira, Vitor B. P. Leite +1
We employ the Bayesian framework to define a cointegration measure aimed to represent long term relationships between time series. For visualization of these relationships we intro…
Underlying Dynamics of Typical Fluctuations of an Emerging Market Price Index: The Heston Model from Minutes to Months
Renato Vicente, Charles M. de Toledo, Vitor B. P. Leite +1
We investigate the Heston model with stochastic volatility and exponential tails as a model for the typical price fluctuations of the Brazilian São Paulo Stock Exchange Index (IBOV…
