Its a bit silly when the model I use outputs integers and then needing to change them to float. --- ## [Employment Categories?](https://community.drivendata.org/t/employment-categories/9026)

Anyone find how to unscramble the employment categories? I can see what the originals are on the CDC’s site but no documentation anywhere as how to decode them. Example: ukymxvdu Thanks! --- ## [What are the hhs\_geo\_regions?](https://community.drivendata.org/t/what-are-the-hhs-geo-regions/5921)

I think that null values in employment\_occupation and employment\_industry is due to the privacy reason. I think that randomly giving NULL values to this columns makes volunteer data much more anonymous.

I understand the scoring is calling for probabilities, not binary 0,1. How did the scorers/judges get these probabilities? It seems like judges only have access to the actual binary 0,1, unless they are mind readers. Wha… --- ## [Test Labels are missing](https://community.drivendata.org/t/test-labels-are-missing/6207)
