Configurable Clinical Information Extraction with Agentic RAG

Agentic RAG systems for clinical data require modular configuration to balance precision and recall, as monolithic pipelines often fail to handle the high variability of medical documentation.

Scaling RAG Pipelines to 10M+ Documents with High Accuracy

To minimize hallucinations at scale, implement a multi-stage RAG pipeline that combines hybrid indexing, reciprocal rank fusion, and a strict 'retrieve, constrain, verify, abstain' workflow that forces the model to cite evidence or admit ignorance.

Fixing RAG Hallucinations Through Better Retrieval Architecture

RAG failures are rarely LLM hallucinations; they are retrieval failures. To fix them, you must move beyond simple semantic search and implement robust document versioning, metadata filtering, and re-ranking.

Improving Financial Document Analysis with GraphRAG

Traditional vector-based RAG struggles with the non-linear, cross-referenced nature of financial documents. GraphRAG improves accuracy and reduces hallucinations by mapping entity relationships, ensuring multi-page data continuity.

Fixing RAG Pipelines by Optimizing Chunking, Not Models

Most RAG failures are caused by poor data retrieval, not model hallucinations. Improving chunking strategy and inspecting raw retrieved data is the most effective way to improve accuracy.

Beyond RAG: Building Hybrid Knowledge Architectures

RAG is effective for static, unstructured retrieval but fails at reasoning, structured data, and long-term memory. Production systems require hybrid architectures that combine retrieval with knowledge graphs and persistent state.

RAG Evolves from Keyword Search to Agentic Reasoning

Information retrieval progressed from keyword matching (TF-IDF/BM25) to semantic vectors, hybrid systems, RAG for LLM augmentation, and agentic setups that autonomously plan retrieval, validate sources, and synthesize multi-step answers.

GraphRAG and Vectorless RAG Fix Vector RAG's Silent Failures

Vector RAG structurally fails by confidently hallucinating on semantically similar but incorrect chunks with no errors logged. GraphRAG maps entity relationships via graphs; Vectorless RAG skips vectors for LLM reasoning over document structure—each excels where the other can't.
