TL;DR. Hybrid systems that combine neural networks for perception/learning with symbolic methods for reasoning, planning, and verification.

Technical Definition

Hybrid systems that combine neural networks for perception/learning with symbolic methods for reasoning, planning, and verification.

How it works

Neuro-symbolic architectures pair an LLM or vision model with a symbolic engine — a SAT solver, theorem prover, knowledge graph, or program interpreter — so each handles what it does best. Examples include AlphaProof (LLM + Lean), AlphaGeometry (LLM + symbolic deduction), DreamCoder, and many tool-augmented agents. The approach targets robust reasoning, interpretability, and data efficiency.

Related Concepts

• Reasoning — An AI system's ability to draw logical, multi-step conclusions from given information.
• Knowledge Graph — A structured representation of knowledge as a network of entities and their relationships.
• Symbolic AI — An approach to AI that attempts to represent human knowledge explicitly using symbols and rules.
