Bounded Invariance and the Formation of Place Fields
نویسندگان
چکیده
One current explanation of the view independent representation of space by the place-cells of the hippocampus is that they arise out of the summation of view dependent Gaussians. This proposal assumes that visual representations show bounded invariance. Here we investigate whether a recently proposed visual encoding scheme called the temporal population code can provide such representations. Our analysis is based on the behavior of a simulated robot in a virtual environment containing specific visual cues. Our results show that the temporal population code provides a representational substrate that can naturally account for the formation of place fields.

Invariance of Fréchet frames under perturbation
Motivating the perturbations of frames in Hilbert and Banach spaces, in this paper we introduce the invariance of Fr'echet frames under perturbation. Also we show that for any Fr'echet spaces, there is a Fr'echet frame and any element in these spaces has a series expansion.
متن کاملEstimation of Scale Parameter Under a Bounded Loss Function
The quadratic loss function has been used by decision-theoretic statisticians and economists for many years. In this paper the estimation of scale parameter under a bounded loss function, which is adequate for assessing quality and quality improvement, is considered with restriction to the principles of invariance and risk unbiasedness. An implicit form of minimum risk scale equivariant ...
متن کاملUniform Convergence to a Left Invariance on Weakly Compact Subsets
Let $left{a_alpharight}_{alphain I}$ be a bounded net in a Banach algebra $A$ and $varphi$ a nonzero multiplicative linear functional on $A$. In this paper, we deal with the problem of when $|aa_alpha-varphi(a)a_alpha|to0$ uniformly for all $a$ in weakly compact subsets of $A$. We show that Banach algebras associated to locally compact groups such as Segal algebras and $L^1$-algebras are resp...
متن کاملExplanation of the Physical Factors Influencing the Formation of Place Attachment Among Newcomers: A Case Study of Elective Urban Spaces of Isfahan
Place attachment is the emotional connection that develops between a person and thephysical environment around them. After more than forty years of research in the field ofplace attachment, the cause and effect as well as the physical factors that affect it have notbeen determined. The features and specifications of a place in both physical and socialdimensions have an influence on the developm...
متن کاملمدل شبکه ی عصبی از نگاشت سلول‌های شبکه به سلول‌های مکانی
Abstract: Medial entorhinal cortex is known to be the hub of a brain system for navigation and spatial representation. These cells increase firing frequency at multiple regions in the environment, arranged in regular triangular grids. Each cell has some properties including spacing, orientation, and phase shift of the nodes of its grid. Entorhinal cortex is commonly perceived to be the major in...
