The information is presented in abstract form by a complex vector which may be expressed directly by a waveform possessing frequency and magnitude.
HAM is part of the family of analog, correlation-based, associative, stimulus-response memories, where information is mapped onto the phase orientation of complex numbers.
Holographs have been shown to be effective for associative memory tasks, generalization, and pattern recognition with changeable attention.
At the heart of this new memory lies a novel bi-modal representation of pattern and a hologram-like complex spherical weight state-space.
HAM typically employs sigmoid pre-processing where raw inputs are orthogonalized and converted to Gaussian distributions.
