- 1. CIIC#5995&100#/#ICOM#5995&100 Human#Perspective#in#Artificial#Intelligence# (HPAI) Professor'José'Meléndez,'PhD https://zoom.us/j/521420068 “At the moment of vision, the eyes see nothing.” ― William Golding, The Spire (191161993)
- 3. Previously+in+HPAI+CIIC/ICOM+5995 • The “Environment” is Reality • Only 5 types of Sensible Energies or Interactions. • Our “Representations” of our Observable Environment Create Our Realities • Human Ears only detect a very small part of what is sonically sensible of Reality • Electronics can do better.
