2. The Focus of AI  Research in AI is concerned with producing machines to automate tasks requiring intelligent behavior. (1)  These automated tasks should be developed to assist people with everyday, necessary tasks that they cannot perform on their own.  Research in AI is concerned with producing machines to automate tasks requiring intelligent behavior.

3. Example: AI and Hearing Aids  A major issue with today’s hearing aids deals with the ability to filter out Noise.

4. Why in Hearing Aids?  In complex, challenging listening situations, hearing impaired patients continue to seek more effective technology.  Current Algorithm:  Prediction based – measures the input signal, to which an assumption is made, an algorithm is engaged and a prediction is made. This is similar to a Simple Reflex Agent.  In complex, challenging listening situations, hearing impaired patients continue to seek more effective technology.  Current Algorithm:  Prediction based – measures the input signal, to which an assumption is made, an algorithm is engaged and a prediction is made.

5. Why in Hearing Aids? (Cont.)  Better Implementation?  Goal Based Agent – “Advanced technology hearing aid systems that perform sophisticated analysis of the communication situation and the acoustic environment, and adjust their performance based on whether or not specific performance goals are met.” (2)  Better Implementation?  Goal Based Agent – “Advanced technology hearing aid systems that perform sophisticated analysis of the communication situation and the acoustic environment, and adjust their performance based on whether or not specific performance goals are met.” (2)

6. New Technology  Oticon Syncro  “Syncro is an advanced technology, eight channel digital hearing instrument incorporating state-of-the-art implementations of adaptive directionality, noise management and wide dynamic range compression.” (2)  Oticon Syncro  “Syncro is an advanced technology, eight channel digital hearing instrument incorporating state-of-the-art implementations of adaptive directionality, noise management and wide dynamic range compression.” (2)

9. The Reasoning behind the Problem  Experts in Artificial Intelligence point out there is a difference in trying to create computer programs that imitate human brain physiology, versus those that try to understand basic challenges of the human brain while finding machine-based solutions to that problem (Ford & Hayes, 2002).
