# Key Concepts

## Overview
This guide explains the core concepts of our cognitive modeling framework, integrating Active Inference with knowledge management.

## Knowledge Structure

### Nodes
Fundamental units of knowledge representation:

#### Agent Nodes
- [[agent_template|Agent Template]]
- Represent cognitive agents
- Contain beliefs, goals, and actions
- See [[agent_concepts]]

#### Belief Nodes
- [[belief_template|Belief Template]]
- Represent probabilistic beliefs
- Update through observations
- See [[belief_concepts]]

#### Goal Nodes
- [[goal_template|Goal Template]]
- Define agent objectives
- Guide policy selection
- See [[goal_concepts]]

### Relationships
- Bidirectional links between nodes
- Represent dependencies and influences
- Follow [[linking_patterns]]

## Active Inference Framework

### Core Principles
1. Free Energy Minimization
   - Drives agent behavior
   - Balances exploration/exploitation
   - See [[free_energy_principle]]

2. Belief Updating
   - Bayesian inference
   - Precision-weighted updates
   - See [[belief_updating]]

3. Policy Selection
   - Expected free energy
   - Action-perception cycles
   - See [[policy_selection]]
