For example there is little in common between biology of birds with aeronautics. So some scientists thinks that it is same in AI, but some also thinks that understanding of how human brain works will help


Artificial intelligence pt. 1

Yesterday we created Artificial intelligence section in company I am working (Prelovac media), so it would be great reason to write about AI.
