كاربرد شبكه هاي عصبي در شناسايي و مدلسازي سيستمها

مقدمه اي بر شبكه هاي عصبي

دلايل استفاده از شبكه هاي عصبي در علوم و صنايع مختلف: 1)قابليت يادگيري 2) قابليت تعميم 3)پردازش موازي 4)مقاوم بودن 5)از شبكه هاي عصبي در جاهايي استفاده مي كنيم كه يكسري داده ورودي-خروجي دارييم كه پديده اش را نمي شناسيم.

كاربردهاي شبكه عصبي: 1)پردازش سيگنال 2) پردازش تصوير 3)شناسايي الگو 4)پزشكي forecasting5) 6)اقتصاد و...
