Document Summary

Each detector has a particular activation level. The status of the detector at that moment how energized the detector is. The activation level will reach the detector"s response threshold. The quantity of activation needed to trigger a response in a detector. The detector will fire send its signal to other detectors to which it"s connected. Detectors involve complex assemblies of neural tissue. Some detectors will be easier to activate than others. Depends on how activated each detector is to begin with. Recency if it"s fired recently warm-up effect. Frequency if it"s fired frequently in the past exercise effect. Detectors needed for recognizing these words have been frequently used. The word will be recognized even with a degraded input. Activation levels will be temporarily lifted (because of recency) A weak signal will be needed to make the detectors fire again. A layer to the net layer with detectors for letter combinations. Bigram detectors - detectors of letter pairs.
