Article on using Embeddings

[edubruell]

Add an article introducing embeddings and demonstrating how to retrieve similar abstracts from a list of embedded economics paper abstracts using tidyllm.

Proposed Content:

1. Intro to Embeddings:

   • Define embeddings and their purpose in capturing semantic relationships.
   • Mention common use cases like similarity search, clustering, or outlier detection in document corpora

2. Practical Example:

   • Embed economics paper abstracts using ollama_embedding() or the other embedding API functions.
   • Calculate cosine similarity to find abstracts similar to a target abstract.
   • Provide code to rank and retrieve the most similar abstracts.

3. Optional:

   • Visualize embeddings with t-SNE.
   • Discuss similarity score interpretation.
