AI Agents

an Agent is defined as a fundamental entity,

who perceives its environment
then makes decisions
then take actions
to achieve a specific target

perceive $\to$ become aware of something / come to realize

Core feedback loop

all agents Act on a feedback loop.

Sensors (perception) - this is how the agent see the environment
- eg: Camera feed, gyroscopes, motion sensors, text inputs, database updates
Decision Maker (brain) - this is the logical part. This evaluate the current state & determine what to do next
- eg: logical program, Machine Learning model
Actuators (actions) - this is how the agent change its environment.
- eg: Clicking a button, increasing a motor speed, output text

an Agent or Not?

	This is not an Agent	This is an Agent
Description	A basic thermometer that displays $72^\circ\text{F}$	An AC that maintain room temperature at $70^\circ\text{F}$
Reason	This perceive environment, but no Action or pursue a goal.	This perceive environment $72^\circ\text{F}$ ,take decision the temperature should be lower,Then reduce the temperature,Keep at $70^\circ\text{F}$ (goal)
