We developed a SaaS solution to increase fashion e-commerce revenue through visual search. Our technology allowed users to take a picture of a garment they liked, and find the most similar garment within the customer's catalog. I led the engineering and sales team. Among our customers, we had one of the biggest e-commerce in the UK and one of the biggest media companies in Spain.

I’ve finished the book: Building AI Agents with LLMs, RAG, and Knowledge Graphs. Really strong book to get a holistic view on how to build agents.

Here are some ideas I found interesting:

𝐇𝐢𝐞𝐫𝐚𝐫𝐜𝐡𝐢𝐜𝐚𝐥 𝐢𝐧𝐝𝐞𝐱𝐢𝐧𝐠:
Problem: If there are too many documents or they are too long, RAG would struggle with precision (chunks are misaligned) or recall (find all relevant chunks).
Solution: We generate a summary of each document and index it with the chunks. At query time, first search over the summaries, and then retrieve the relevant chunks.

𝐒𝐞𝐥𝐟-𝐑𝐀𝐆:
Problem: The query is too complex.
Solution: Use a multi-step process to critique and reflect on the output.

𝐆𝐫𝐚𝐩𝐡𝐑𝐀𝐆:
Problem: Traditional RAG fails to capture relationships and struggles with redundant information.
Solution: Use a Knowledge Graph, composed as tripplets of entity-relation-entity, as a controlled context to increase relevance.

𝐆𝐫𝐚𝐩𝐡 𝐨𝐟 𝐓𝐡𝐨𝐮𝐠𝐡𝐭 (𝐆𝐨𝐓):
Problem: The query is too complex.
Solution: Use multiple reasoning steps in graph form to explore alternative answers and verify the final output.

𝐄𝐱𝐩𝐥𝐚𝐢𝐧𝐚𝐛𝐥𝐞 𝐑𝐞𝐢𝐧𝐟𝐨𝐫𝐜𝐞𝐦𝐞𝐧𝐭 𝐋𝐞𝐚𝐫𝐧𝐢𝐧𝐠 (𝐗𝐑𝐋):
Problem: It’s not easy to understand the agent's behavior in an RL setting.
Solution: Use an LLM as a policy interpreter to explain the agent’s behavior.
