Episode notes
What is Vector Search?
- Vectors are high-dimensional representations of data, created by sending data through an embedding model.
- These vectors are series of numbers representing the underlying data, like text or images.
Vectors as Points in N-Dimensional Space
- A vector represents a point in n-dimensional space, describing content.
- Comparing vector distances reveals content similarity, like how similar two articles are.
Embeddings and Pre-trained Models
- Embeddings convert content into vectors using pre-trained models, often from sources like Google or OpenAI.
- These models have generalized knowledge, making semantic search accessible and easy.
