Patient Information about Epilepsy & Seizures. Epilepsy, or seizure disorder, is a chronic neurological condition caused by abnormal brain cell activity. Epilepsy is characterized by recurrent seizuresâhaving one seizure does not necessarily mean that a person has epilepsy.
(1971) â¢ Discriminability was measured by an increase in sucking rate toa second speech sound after habituation to the first sound. â¢ Recovery from habituation was greater when the two stimuli were from different adult phonemiccategories than when they were from the same category. Eimas et al.1971) reported that infants, like adults, demonstrate categorical ppp p perception for speech sounds. To explain this they proposed that infants are equipped with innate, speech-specific, phoneticfeature detectors tuned to the range of phonetic contrasts used in the worldâs languages.
Feature extraction creates new features from functions of the original features, whereas feature selection returns a subset of the features. Feature selection techniques are often used in domains where there are many features and comparatively few samples (or data points).
