What is RAG?

​

LLM Hallucinations - providing incorrect responses to queries

• Insufficient or stale data
• Overloaded context window

​

​

• Trained on public data
• Training data is stale

​

​

Context window - the amount of information considered by the LLM

​

• Limited in scope

​

​

Retrieval-Augmented Generation:

• Combines embedding and generation models
• Generates answer based on retrieved info

Data Ingestion

• Identify data sources
• Prepare the data
• Store the data

​

Our app should:

• Answer questions about MongoDB
• Use “The Little Book of MongoDB” as a data source

​

Data Ingestion

• Identify data sources
• Prepare the data
1. Sanitize the data
2. Chunk the data
3. Create embeddings
• Store the data

Sanitizing - removing any sensitive or unnecessary data

Account for multiple data formats.

Convert everything to the same format

​

• e.g. Markdown

Chunking - breaking text into small pieces

​

• Efficient indexing

Common Methods of Chunking:

• Sentence
• Paragraph
• Page
• Section
• Semantically

dev.to/busycaesar

Keep chunks up to date!

​

• Atlas Triggers
• cron job

Retrieval

Retriever:

• finds chunks relevant to the query
