What is: Reinforcement Learning (Interactive Learning in Decision Processes)?

— Is there a way to learn by interacting

— i.e. interact have experience and use the experience to learn (predict the future)

— Interact to explore and utilize what makes learning (goal/outcome) enhanced

— The computation approach of this method is Reinforcement Learning (Interactive Learning in Decision Processes)?

— it is a goal oriented learning from interactions

— it has it’s root in Markov decision process (MDP)

— Markov decision process (MDP) is a model for sequential decision making when outcomes are uncertain.[1] [Wikipedia]

Reinforcement Learning (Interactive Learning in Decision Processes) Involves:

Markov decision processes
Dynamic Programming
Monte Carlo methods
Temporal-difference learning
Function approximation methods

Monte Carlo methods

Solves problems with repeated random sampling.

Temporal-difference learning: combination of the Monte Carlo (MC) method and the Dynamic Programming (DP) method.

Function approximation methods

yum upgrade and yum update

“yum upgrade and yum update will perform the same function that update to the latest current version of package. But the difference is Upgrade will delete obsolete packages, while update will preserve them.Jul 3, 2014”
