Area Description Status Hypothesis Generation Use of LLMs to generate novel, testable hypotheses from goal/context ✅ Implemented in GenerationAgent with DSPy Self-Critique / Reflection Critically review generated hypotheses for clarity, novelty, testability ✅ Implemented via ReflectionAgent using DSPy Ranking / Evaluation Pairwise comparison of hypotheses using ELO-style ranking ✅ Fully implemented with trace logging Evolution & Grafting Improve top hypotheses through evolution and hypothesis merging ✅ Implemented in EvolutionAgent with grafting logic Meta-Review / Summary Generate a unified research direction based on evolved hypotheses ✅ Done with MetaReviewAgent and DSPy Vector Memory Store and retrieve hypotheses using vector similarity ✅ Implemented with PostgreSQL + pgvector Embeddings High-quality local embeddings for hypothesis and query comparison ✅ Done using nomic-embed-text via Ollama Traceability Full logging of decisions, scores, explanations ✅ CLI dashboard + DB logging YAML Pipeline Config Modular config to control pipeline flow ✅ Done with pipeline.yaml and PipelineRunner Tooling & CLI View ELO evolution and trace decisions ✅ Done with view_ranking_trace.py 🚀 What We’ve Extended Beyond the Paper Feature Description DSPy Integration Modularized all logic into composable DSPy Signatures and Modules Grafting Introduced “hypothesis grafting” as an optional step to merge similar ideas Full Pipeline CLI YAML-configurable end-to-end execution (run_pipeline.py) ELO Visualization Added CLI-based ranking visualization (top scores + ELO evolution) Local-first Design Works 100% locally using Ollama, Postgres, and pgvector Extensible Memory Interface Abstracted memory layer to allow swaps (e.g., Haystack, Weaviate) Meta Reasoning Hooks Ready for Teleprompter optimization, critic loops, and reward models 🔬 Further Research / Expansion Areas Area Opportunity 🧠 Teleprompter Optimization Train DSPy modules to optimize performance with real data 🔁 Multi-run Feedback Loops Feed output summaries back into new runs to deepen hypotheses 🧪 Experiment Tracking Add support for tracking actual test results or experiments 📊 Evaluation Benchmarks Compare hypothesis quality across LLMs or ranking methods 🌐 RAG Integration Augment hypothesis generation with external sources + citations 🧬 Domain-Specific Models Swap in fine-tuned scientific LLMs (e.g. SciPhi, BioGPT) 🧩 Multi-Agent Dialogues Enable collaborative debate between hypotheses or roles 💾 Exportable Reports Generate PDF or Markdown summary reports from any run 🧱 UI/Dashboard Add a Streamlit or web dashboard to manage runs + inspect logs 🔒 Security / Logging Audit trail and rollback for sensitive or research-critical systems
