Dynamical Mechanisms in Multi-agent Systems: Minority Games
K. Y. Michael Wong, S. W. Lim, Zhuo Gao
We consider a version of large population games whose agents compete for resources using strategies with adaptable preferences. Diversity among the agents reduces their maladpative…
Mean-field theory of learning: from dynamics to statics
K. Y. Michael Wong, S. Li, Peixun Luo
Using the cavity method and diagrammatic methods, we model the dynamics of batch learning of restricted sets of examples. Simulations of the Green's function and the cavity activat…
Sacrificial Learning in Nonlinear Perceptrons
Peixun Luo, K. Y. Michael Wong
Using the cavity method we consider the learning of noisy teacher-generated examples by a nonlinear student perceptron. For insufficient examples and weak weight decay, the activat…
Phase Transition in a Noise Reduction Model: Shrinking or Percolation?
J. van Mourik, K. Y. Michael Wong, D. Bolle'
A model of noise reduction (NR) for signal processing is introduced. Each noise source puts a symmetric constraint on the space of the signal vector within a tolerable overlap. Whe…
