Hierarchical sparse coding in the sensory system of Caenorhabditis elegans

TL;DR: The functional map reveals that despite the dense wiring, chemo- and mechano-sensory neurons represent the environment using sparse codes, a strategy that mitigates the limited size and the shallow structure of the neural network.

The HTM Spatial Pooler-A Neocortical Algorithm for Online Sparse Distributed Coding.
TL;DR: This paper analyzes an important component of HTM, the HTM spatial pooler (SP), and describes a number of key properties, including fast adaptation to changing input statistics, improved noise robustness through learning, efficient use of cells, and robustness to cell death.
Journal ArticleDOI
The Hebbian paradigm reintegrated: Local reverberations as internal representations
TL;DR: The concept of the local neighborhood should be expanded to spatial patterns as the basis for perception, in which large areas of cortex are bound into cooperative behavior with near-silent columns as important as active columns revealed by unit recording.

Temporal sparseness of the premotor drive is important for rapid learning in a neural network model of birdsong
TL;DR: If songbirds acquire their songs under significant pressure to learn quickly, this study predicts that HVC activity should also be sparse during the sensorimotor phase in the juvenile bird, and derives a relationship between sparse activity, synaptic interference, and learning time.

The CRISP theory of hippocampal function in episodic memory
TL;DR: It is suggested that CRISP is a viable, and perhaps superior, theory for the hippocampal function in episodic memory, and for results that are at odds with the standard framework.

Theory of Optical Information Storage in Solids
TL;DR: The theory of three-dimensional optical storage lends support to Beurle’s proposed mechanism of information storage in the brain, and makes three- dimensional storage very suitable for associative memories.

Holographic Model of Temporal Recall
TL;DR: It is shown that there is at least one other mathematical model, which is considered to be a closer analogue of holography, because it operates with triple products of the temporal function to be recognized or recalled.

Improved holographic model of temporal recall.
TL;DR: The modified static system described here is an alternative to Longuet-Higgins' model and takes account of the weaknesses of the nervous system as well as of its powers to imitate human memory with models.

The Classification of Modifiable Synapses and Their Use In Models For Conditioning
TL;DR: It is argued that if the conditioning and memory mechanisms of the nervous system store information by means of modifiable synapses, some of these must be of class B or C, and if the models are to be given the property of extinction, classical conditioning requires modifiablesynapses of classes A and B or of class C.
