Abstract
A feature-pattern extraction apparatus uses a logarithmic transformation processing to extract a feature pattern from a myoelectric pattern that is a muscle action potential. The extracted feature patterns are classified, and an output control signal is generated. By using the logarithmic transformation processing to extract feature patterns, distribution bias is reduced, improving classification accuracy.
