Currently, I follow a simple format to disseminate knowledge on Threads. I post concepts and interesting questions (IQs) as they come to my ENTP brain, which I have used in my professional journey and academia, have been asked in interviews, or that I could potentially ask in a data science interview. Once I have a question ready, I refine it to cover as many concepts as possible. Sometimes, I choose questions that are particularly thought-provoking to stimulate deeper discussions.
Contributions are welcome! If you have suggestions for new questions, additional resources, or improvements to the current answers, feel free to submit a pull request or open an issue.

The goal is to allow researchers to have a baseline of how well their model and entire inference pipeline is doing against different harm categories and to be able to compare that baseline to future iterations of their model. This allows them to have empirical data on how well their model is doing today, and detect any degradation of performance based on future improvements.
