Black box problem of machine learning. AI gives answers to humans, but humans do not understand why it gives such an answer. Effort to alleviate this situation has been taken.
Human longevity has a limit of 115. Evidence: the age with the greatest improvement in survival has been plateaued for years. So has been the maximum reported age of dying.
Specifically, bees that were given a reward of sugar water before a choice between two neutral cues responded as though the cues were positive stimuli. Further, bees given sugar water were more resilient in the face of a simulated predator attack
A model is proposed to track the dispersal of early humans (from 20kya) from Africa to other continents. It calculates the environmental capacity to hold humans from climate change.
Can we open the black box of AI?
