How did you train SparseEmbed?

[richardklafter]

First, awesome project!

How did you train your model at https://huggingface.co/raphaelsty/neural-cherche-sparse-embed? Did you train it from scratch? I found an old copy of your sparsembed library. Was that library used or was this repository? What data did your train on exactly?

I am surveying various sparse embedding models and SparseEmbed while interesting has very little code or docs beyond the original google paper. Any assistance would be appreciated. Thanks!
