Meta-learning for improved retrieval in LLMs
Meta-learning in retrieval systems is a dynamic approach where the model learns to improve its retrieval strategy by analyzing past performance and relevance feedback. In this implementation, meta-learning focuses on selecting and ranking documents adaptively based on learned relevance patterns.
Let’s implement a simple meta-learning approach for RAG.
The following code demonstrates meta-learning by retrieving documents about dark matter theories and simulating relevance feedback to train the model, showcasing how the system can improve its information retrieval capabilities iteratively:
import numpy as np from sklearn.linear_model import LogisticRegression class MetaLearningRAG: def __init__(self, retriever, generator): self.retriever = retriever self.generator = generator ...
