Agents

Simple reflex Agent

• non-perceptual part = data that cannot be obtained from sensor?
  • if vaccum cleaner me temp sensor nahi hai, it can’t find temp, and agar temp high ho, then it might not be able to work

Model Based Reflex Agent

• partially observable?
  • eg vaccum cleaner me I only know about current cell ki dirty hai ya nahi, neighbors ka idk

• it has better understanding of the world

Goal Based agent

• goal = clean all the tiles

• there are no rules now
• we check if taking an action takes me closer to goal or not

Utility Based Agent

• main diff is in terms of optimization
• like what is shortest path to reach the destination

• goal based, onnly focused on goal, did not care about the time it took

• dekh 3 selectio strategies thi na
  • greedy
  • epsilon-greedy
  • softmax
    • so this will check ki kaunsa lu

Learning Agent

• Can it generalize
• if it has learnt to recognize obj a, can it generalize to recognize obj b
• neural n/w me bhi mistake se learn

• it is like supervised learning
