Generative Pseudo Labeling (GPL): Unsupervised Learning in Semantic Search

Hi all, I wanted to share an article I wrote covering [Generative Pseudo-Labeling (GPL)](https://www.pinecone.io/learn/gpl/). It's a really cool technique from Kexin Wang and co (N Reimers' UKPLab) that allows us to adapt sentence transformer models to new domains using nothing more than unlabeled text data. It works by generating synthetic (query, positive, negative) triplets and margin scores, which are then used with margin MSE loss to fine-tune the sentence transformer.

Very interesting technique, if you're working in the space I'd …
