Neuro-Symbolic Boost for ARC Reasoning

🔑 Enhanced Key Takeaways

• •The architecture utilizes a 'Visual-to-Symbolic' bridge that converts raw grid pixels into a graph-based representation, allowing the neural component to reason over object relationships rather than raw tokens.
• •The system employs a 'Consistency-Driven Pruning' mechanism that discards transformation candidates if they fail to satisfy the constraints of all provided training examples within a single ARC task.
• •The meta-classifier used to integrate the ARC Lang Solver is trained on a synthetic dataset of 50,000 ARC-like puzzles to learn when to defer to the symbolic solver versus the neural-proposed transformations.

🛠️ Technical Deep Dive

• •Perception Module: Uses a lightweight CNN-based encoder to identify connected components and color-based clusters, outputting a graph structure.
• •Transformation Proposal: Employs a frozen LLM (e.g., GPT-4o or Llama-3-70B) prompted with the graph structure to generate DSL (Domain Specific Language) code snippets.
• •Symbolic Filtering: Executes generated DSL code against the input grid; candidates that produce invalid outputs or fail to match the transformation pattern of the training examples are pruned.
• •Meta-Classifier: A lightweight Random Forest classifier that predicts the probability of success for the neural-proposed path versus the symbolic solver path based on task complexity features.
