Training recurrent networks to generate hypotheses about how the brain solves hard navigation problems [article]

Ingmar Kanitscheider, Ila Fiete
2016 arXiv   pre-print
Self-localization during navigation with noisy sensors in an ambiguous world is computationally challenging, yet animals and humans excel at it.  ...  The hidden unit representations exhibit several key properties of hippocampal place cells, including stable tuning curves that remap between environments.  ...  The SH algorithm can be thought of as an abstraction of neural bump attractor models [13, 14] , in which an activity bump is updated using PI and corrected when a landmark or boundary with known spatial  ...

Exact theory of polymer adsorption in analogy with the Kondo problem

P Fendley, H Saleur
1994 Journal of Physics A: Mathematical and General  
More generally, we solve the special transition in the O(n) model, the polymer case corresponding to n=0. The n=2 limit appears identical to the ordinary Kondo problem.  ...  We conjecture the exact scaling theory for the adsorption of two-dimensional polymers by using boundary S matrices.  ...  This is very likely since the conformal minimal models with Φ 1,3 perturbation on the boundary are integrable [8] , and the O(n) models with energy perturbation on the boundary share many properties with  ...

Multiple shocks in a driven diffusive system with two species of particles

2005 Physica A: Statistical Mechanics and its Applications  
A one-dimensional driven diffusive system with two types of particles and nearest neighbors interactions has been considered on a finite lattice with open boundaries.  ...  We will show that on a special manifold in the parameters space multiple shocks evolve in the system for both species of particles which perform continuous time random walks on the lattice.  ...  Two-species model with open boundaries The model is defined on a finite lattice of length L with two species of particles.  ...

Boundary polarization in the six-vertex model

N. M. Bogoliubov, A. V. Kitaev, M. B. Zvonarev
2002 Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics  
Vertical-arrow fluctuations near the boundaries in the six-vertex model on the two-dimensional N × N square lattice with the domain wall boundary conditions are considered.  ...  This representation is used to study the large N limit: the presence of the boundary affects the macroscopic quantities of the model even in this limit.  ...  Some correlation functions for the inhomogeneous model (the model with the statistical weights depending on the position of the vertex) with special choice of the weights were considered in Ref.  ...

Karla A. V. Borges, Alberto H. F. Laender, Clodoveu A. Davis
1999 Proceedings of the seventh ACM international symposium on Advances in geographic information systems - GIS '99  
However, it is clear that modeling geographic data requires models which are more specific and capable of capturing the semantics of geographic data.  ...  paper discusses the relationship that exists between the nature of spatial information, spatial relationships, and spatial integrity constraints, and proposes the use of OMT-G, an extension of the OMT model  ...  between the mental model of the space to be modeled and the usual representation model.  ...

Partition function of the elliptic solid-on-solid model as a single determinant

W. Galleas
2016 Physical review. E  
In this work we express the partition function of the integrable elliptic solid-on-solid model with domain-wall boundary conditions as a single determinant.  ...  This representation appears naturally as the solution of a system of functional equations governing the model's partition function.  ...  Boundary conditions are among the main ingredients when defining a lattice statistical system and the elliptic sos model with domain-wall boundaries has received special attention recently.  ...
