Exploring the Neural Manifold

چکیده
Anyone who has experienced change blindness (in which a large difference between two images goes unnoticed [1]) knows that while our brain is supposed to efficiently process the sensory inputs from our natural environment, it can be tricked by well-designed stimuli. In the visual system, this is best reflected by optical illusions in which two physically different stimuli appear identical. For example, the perceived brightness of an area can be greatly influenced by the luminance of the surrounding areas: a gray patch on a dark background can appear as bright as a darker patch on a bright background [2]. These illusions suggest that physically different stimuli will trigger identical responses in a part of the visual system. Searching for the neural basis of such illusions is a major challenge in sensory neuroscience. Some researchers have found that perceived illusions can be reflected in the firing rate of single neurons [3] or populations of neurons [4].

Manifold learning is a dimension reduction method for extracting nonlinear structures of high-dimensional data. Many methods have been introduced for this purpose. Most of these methods usually extract a global manifold for data. However, in many real-world problems, there is not only one global manifold, but also additional information about the objects is shared by a large number of manifolds...
متن کاملGrowing Locally Linear Embedding for Manifold Learning
Locally linear embedding is an effective nonlinear dimensionality reduction method for exploring the intrinsic characteristics of high dimensional data. This paper proposes a new manifold learning method, which is based on locally linear embedding and growing neural gas and is termed growing locally linear embedding (GLLE). GLLE overcomes the major limitations of the original locally linear emb...

This paper deals with the problem of face recognition from a single image per person by producing virtual images using neural networks. To this aim, the person and variation information are separated and the associated manifolds are estimated using a nonlinear neural information processing model. For increasing the number of training samples in neural classifier, virtual images are produced for...

In this paper, we extend Sasaki metric for tangent bundle of a Riemannian manifold and Sasaki-Mok metric for the frame bundle of a Riemannian manifold [I] to the case of a semi-Riemannian vector bundle over a semi- Riemannian manifold. In fact, if E is a semi-Riemannian vector bundle over a semi-Riemannian manifold M, then by using an arbitrary (linear) connection on E, we can make E, as a...
