The capacity of the Hopfield associative memory
Techniques from,coding theory are applied to study rigorously the capacity of the Hopfield associative memory. Such a memory stores n -tuple of + 1’s. The components change depending on a hardlimited version of linear functions of all other components. With symmetric connections between components, a stable state is ultimately reached. By building up the connection matrix as a sum-of-outer prod...
متن کاملProbabilistic Information Capacity of Hopfield Associative Memory
T his pap er defines a form al pr obabilist ic notion for the information capac ity of the Hopfield neur al network model of associat ive memory. A mathematical express ion is derived for the number of random binary pat terns that can be stored as stable states in a Hopfield model of memory with n neur ons with a given probab ility. The derivati on is based on a new approach using two powerfu l...
متن کاملAdaptation of Hopfield Associative Memory Parameters
The paper treats the issue of pattern recognition training in terms of Hopfield associative memory (HAM). The conventional randomization technique is used to determine the exponential extremity of HAM recognition error. The extremity exponent is considered as a function of the training process. In training, the exponent is shown to rise from (1-2p) to (1-2p) where p is the error coefficient at ...
متن کاملCapacity of Bidirectional Associative Memory
The capacity of Bidirectional associative memory (BAM) was examined a lot in research, but not completely. In particular, this issue was not investigated in the context of strings coding. In this paper we apply different approaches to estimate the capacity of BAM for strings coding. One of these approaches is recalling of all coded strings. Another is applying Hamming and Levenshtein distances ...
