  • nature s Learning rule the hebbian lms algorithm
    IEEE International Conference on Cognitive Informatics and Cognitive Computing, 2018
    Co-Authors: Bernard Widrow
    Abstract:

    Hebbian Learning is widely accepted in the fields of psychology, neurology, and neurobiology. It is one of the fundamental premises of neuroscience. The LMS (least mean square) algorithm of Widrow and Hoff is the world's most widely used adaptive algorithm, fundamental in the fields of signal processing, control systems, communication systems, pattern recognition, and artificial neural networks. These Learning paradigms are very different. Hebbian Learning is unsupervised. LMS Learning is supervised. However, a form of LMS can be constructed to perform unsupervised Learning and, as such, LMS can be used in a natural way to implement Hebbian Learning. Combining the two paradigms creates a new unsupervised Learning algorithm, Hebbian-LMS. This algorithm has practical engineering applications and provides insight into Learning in living neural networks. A fundamental question is, how does Learning Take Place in living neural networks? “Nature's little secret,” the Learning algorithm practiced by nature at the neuron and synapse level, may well be the Hebbian-LMS algorithm.

Hebbian Learning is unsupervised. LMS Learning is supervised. However, a form of LMS can be constructed to perform unsupervised Learning and to implement Hebbian Learning.

  • perception cognition and action in hyperspaces implications on brain plasticity Learning and cognition
    Frontiers in Psychology, 2020
    Co-Authors: Haluk Ogmen, Kazuhisa Shibata, Arash Yazdanbakhsh
    Abstract:

    We live in a three-dimensional (3D) spatial world; however, our retinas receive a pair of 2D projections of the 3D environment. By using multiple cues, such as disparity, motion parallax, perspective, our brains can construct 3D representations of the world from the 2D projections on our retinas. These 3D representations underlie our 3D perceptions of the world and are mapped into our motor systems to generate accurate sensorimotor behaviors. Three-dimensional perceptual and sensorimotor capabilities emerge during development: the physiology of the growing baby changes hence necessitating an ongoing re-adaptation of the mapping between 3D sensory representations and the motor coordinates. This adaptation continues in adulthood and is quite general to successfully deal with joint-space changes (longer arms due to growth), skull and eye size changes (and still being able of accurate eye movements), etc. A fundamental question is whether our brains are inherently limited to 3D representations of the environment because we are living in a 3D world, or alternatively, our brains may have the inherent capability and plasticity of representing arbitrary dimensions; however, 3D representations emerge from the fact that our development and Learning Take Place in a 3D world. Here, we review research related to inherent capabilities and limitations of brain plasticity in terms of its spatial representations and discuss whether with appropriate training, humans can build perceptual and sensorimotor representations of spatial 4D environments, and how the presence or lack of ability of a solid and direct 4D representation can reveal underlying neural representations of space.
