New Boltzmann Machine Models Complex Audio Signals in Polar Coordinates

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced PolarBM, a novel Boltzmann machine designed to handle complex-valued variables in audio signal processing. Unlike traditional methods that simplify complex data to real values, PolarBM explicitly models the relationship between amplitude and phase. An extension, LogPolarBM, further processes audio signals based on human auditory perception by modeling amplitude on a logarithmic scale. These models, including their restricted variants PolarRBM and LogPolarRBM, have demonstrated superior accuracy in experiments compared to conventional models like deep neural networks, with potential applications beyond audio in fields such as wireless communications and quantum mechanics. AI
