Correlation matrix memories

Teuvo Kohonen
TL;DR: In this article, a new model for associative memory based on a correlation matrix is proposed, which is failure tolerant and facilitates associative search of information; these are properties that are usually assigned to holographic memories.
Journal ArticleDOI

Synaptic plasticity and learning: selective impairment of learning rats and blockade of long-term potentiation in vivo by the N-methyl-D-aspartate receptor antagonist AP5.

TL;DR: The results show that chronic intraventricular infusion of the NMDA receptor antagonist D,L-2-amino-5-phosphonopentanoic acid (D,L, AP5) caused an impairment of spatial but not of visual discrimination learning in rats.

Correlation Matrix Memories

TL;DR: A new model for associative memory, based on a correlation matrix, is suggested, in which any part of the memorized information can be used as a key and the memories are selective with respect to accumulated data.

Excitation-Neurogenesis Coupling in Adult Neural Stem/Progenitor Cells

TL;DR: It is demonstrated that excitatory stimuli act directly on adult hippocampal NPCs to favor neuron production and, when applied as an "excitation-neurogenesis coupling rule", predict significant advantages for both the temporary storage and the clearance of memories.

Artificial neural networks in hardware: A survey of two decades of progress

TL;DR: This article presents a comprehensive overview of the hardware realizations of artificial neural network models, known as hardware neural networks (HNN), appearing in academic studies as prototypes as well as in commercial use.

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.
Journal ArticleDOI

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.
