Pattern recognition with magnonic holographic memory device

Optoelectronic Device using a Liquid Crystal Holographic Memory

Recently, the technologies related to liquid crystal spatial light modulators have progressed dramatically [1]–[4]. Such modulators are classifiable as two types: transmissive and reflective. Both types are used widely for various applications, e.g. liquid crystal television panels, personal computer displays, and projector systems. In particular, the resolution of the latest liquid crystal spa...

Holographic memory with localized recording.

We experimentally demonstrate and characterize a memory module that features selective page erasure and readout persistence using the localized recording method in doubly doped LiNbO(3). Pages of information can be selectively erased without partially erasing the whole memory. Data pages can be written over erased pages multiple times. Information is read millions of times before refreshing is ...

Dynamic Pattern Recognition and Data Storage Using Localized Holographic Recording

Stochastic resonance in pattern recognition by a holographic neuron model.

The recognition rate of holographic neural synapses, performing a pattern recognition task, is significantly higher when applied to natural, rather than artificial, images. This shortcoming of artificial images can be largely compensated for, if noise is added to the input pattern. The effect is the result of a trade-off between optimal representation of the stimulus (for which noise is favorab...

An Effective Associative Memory for Pattern Recognition

Neuron models of associative memory provide a new and prospective technology for reliable date storage and patterns recognition. However, even when the patterns are uncorrelated, the efficiency of most known models of associative memory is low. We developed a new version of associative memory with record characteristics of its storage capacity and noise immunity, which, in addition, is effectiv...
