3 Machine Intelligence – Evaluation Functions and Numerical Convergence

Two issues appear when a reward matrix (R)-driven MDP produces results. These issues can be summed up in two principles.

Principle 1: AI algorithms often surpass humans in classification, prediction, and decision-making areas.

The key executive function of human intelligence, decision-making, relies on the ability to evaluate a situation. No decision can be made without measuring the pros and cons and factoring the parameters.

Humanity takes great pride in its ability to evaluate. However, in many cases, a machine can do better. Chess represents our pride in our thinking ability. A chessboard is often present in movies to symbolize human intelligence.
