Many years ago, we embraced deep learning for dropping feature engineering, now we have prompt engineering 🤦 then IR is back with RAG and query expansion. Seems there isn't much difference between fashion trends and research trends in the way that they always come back 😅

📃Advanced RAG: Query Transformations

We've added a few advanced RAG methods over the past few days that all fall under a similar abstraction: "Query Transformations"

✒️Rewrite-retrieve-read
🧨RAG-Fusion
🏃Step-back prompting

We've written a blog on this "Query Transformation" abstraction, detailing how we see the space

🔎It's worth noting that this not new - search engines like Google have been doing query expansion for years

💬What is new is using LLMs to do it. All of the above methods (and others outlined in the post) uses an LLM to transform a query into a different (or multiple) queries

The main difference is the prompt used!

Just checked the documentation, worth giving it a try

[JohnSnowLabs @JohnSnowLabs]

Need NLP?
Give #SparkNLP 2.0 a try!
Why?
It makes half the errors that SPACY makes on named entity recognition (NER). Besides, It obtained the best performing academic pre-reviewed results. It is also faster than SPACY to train #NLP models locally.

#Brexit seems more challenging and time consuming than tuning parameters of deep neural networks
