How it works

The agent uses Q-Learning to estimate the value of each action. Higher probabilities indicate more promising actions based on past experience.

// Learning Progress

Q-Values for current state (sample)

UP 0.00 0
DOWN 0.00 0
LEFT 0.00 0
RIGHT 0.00 0

Q-Learning Formula

Q(s,a) ← Q(s,a) + α[r + γ·max Q(s',a') - Q(s,a)]

  • α = Learning rate (how much to update)
  • γ = Discount factor (future vs. immediate)
  • r = Immediate reward
  • s, a = State and action

// Understanding Autonomous Agents

What are Autonomous Agents?

Autonomous agents are AI systems that perceive their environment, make decisions, and take actions to achieve goals without continuous human intervention. They learn from experience through reinforcement learning, improving their behavior over time.

Key Concepts

  • Perception: Agents observe their environment and maintain state information
  • Decision Making: Choose actions based on learned policies or value functions
  • Learning: Update knowledge from rewards and penalties (reinforcement signals)
  • Exploration vs. Exploitation: Balance between trying new actions and using known good ones
  • Temporal Credit Assignment: Determine which actions led to rewards or penalties

Real-World Applications

  • Robotics navigation and manipulation
  • Game playing (AlphaGo, chess engines, Dota 2)
  • Autonomous vehicles (self-driving cars)
  • Resource optimization (data center cooling, trading)
  • Personalized recommendations and content delivery
