# Processing BORU
This is a space to visually search the subreddit [/r/bestofredditorupdates](https://www.reddit.com/r/BestofRedditorUpdates/). 
Have you ever been curious to search for stories that are similar to one of your favorites? This can help!

- Each dot represents a post (try clicking on one)
- Closer dots are similar in topic
- Use the filters on the left to help you narrow down what you are looking for
    - The lasso can help you search in a smaller range that you drag with your mouse
    - The filter can help you narrow by field, 
        - Filtering posts that are `CONCLUDED`
        - Filtering popular posts
        - Filtering by date
    - The search can help you look by keyword

# Details
## Creation Details
1. This space is triggered by a webhook for changes on [derek-thomas/dataset-creator-reddit-bestofredditorupdates](https://huggingface.co/datasets/derek-thomas/dataset-creator-reddit-bestofredditorupdates).
2. It then takes the updates from that dataset and get embeddings by making leveraging [derek-thomas/nomic-embeddings](https://huggingface.co/spaces/derek-thomas/nomic-embeddings)
    - [derek-thomas/nomic-embeddings](https://huggingface.co/spaces/derek-thomas/nomic-embeddings) is using [zero-spaces](https://huggingface.co/zero-gpu-explorers) a free GPU service
    - Im calling this via [gradio_client](https://www.gradio.app/docs/client) which allows any space to be used as an API
3. The calculated embeddings are stored in this dataset [derek-thomas/reddit-bestofredditorupdates-processed](https://huggingface.co/datasets/derek-thomas/reddit-bestofredditorupdates-processed)
4. These get visualized by [nomic atlas](https://docs.nomic.ai/atlas/introduction/quick-start). You can see how I process it in [build_nomic.py](https://huggingface.co/spaces/derek-thomas/processing-bestofredditorupdates/blob/main/src/build_nomic.py)

## Todo
- Ignore the colors for now, I need to clean that up :) 
- I need to integrate with Nomic's semantic search
