RAG & Embedding Fine-Tuning


Overview

Providing the NLP technical grounding required for robust memory systems. This project involved fine-tuning embedding models on domain-specific conversational datasets to improve retrieval accuracy in Retrieval-Augmented Generation pipelines.

Details

COMPONENTS

Contrastive learning techniques applied to Sentence-Transformers, vector database optimization, and custom reranking heuristics.

RESULTS

Achieved a 24% improvement in top-k retrieval accuracy for ambiguous conversational queries compared to baseline models.
