I think it’s great they’ve finally done it, though from my obverservations, there’s little resemblance of what the…
Text classification is a very frequent use case for machine learning (ML) and natural language processing (NLP). It’s used for things like spam detection in emails, sentiment analysis for social media posts, or intent detection in chat bots. In this series I am going to compare several libraries that can be used to…

I finally escaped from (grad) school in 2019, spent two months interning as an assistant trader at FTX, and have since spent the last two years working as a data scientist, with the bulk of that time at Microsoft and the last two months at Anthropic. Not gonna lie — my time as a data scientist has been pretty awesome…
