Introduction to Neurosymbolic AI

🎯 What is Neurosymbolic AI?

Neurosymbolic AI integrates neural networks (learning from data) with symbolic reasoning (logic, rules, knowledge graphs) to create systems that are both learnable and interpretable.

🔗
Best of Both Worlds

Neural learning + symbolic reasoning = robust, explainable AI

⚖️ Neural vs Symbolic

Neural Systems

✓Learn from raw data
✓Handle uncertainty
✗Black box reasoning
✗Data hungry

Symbolic Systems

✓Interpretable logic
✓Knowledge integration
✗Brittle to noise
✗Manual rule crafting
