Statistical mechanics of digital halftoning
Jun-ichi Inoue, Yohei Saika, Masato Okada
We consider the problem of digital halftoning from the view point of statistical mechanics. The digital halftoning is a sort of image processing, namely, representing each grayscal…
Retrieval of branching sequences in associative memory model with common external input and bias input
Kentaro Katahira, Masaki Kawamura, Kazuo Okanoya +1
We investigate a recurrent neural network model with common external and bias inputs that can retrieve branching sequences. Retrieval of memory sequences is one of the most importa…
Stochastic transitions of attractors in associative memory models with correlated noise
Masaki Kawamura, Masato Okada
We investigate dynamics of recurrent neural networks with correlated noise to analyze the noise's effect. The mechanism of correlated firing has been analyzed in various models, bu…
Theory of Recurrent Neural Network with Common Synaptic Inputs
Masaki Kawamura, Michiko Yamana, Masato Okada
We discuss the effects of common synaptic inputs in a recurrent neural network. Because of the effects of these common synaptic inputs, the correlation between neural inputs cannot…
Short-term Synaptic Depression Improves Error-correcting Ability in Cortical Circuits
Narihisa Matsumoto, Daisuke Ide, Masataka Watanabe +1
Synaptic connections are known to change dynamically. High-frequency presynaptic inputs induce decrease of synaptic weights. This process is known as short-term synaptic depression…
Residual Energies after Slow Quantum Annealing
Sei Suzuki, Masato Okada
Features of the residual energy after the quantum annealing are investigated. The quantum annealing method exploits quantum fluctuations to search the ground state of classical dis…
