Frequently Asked Questions

What is the best machine learning subreddit?

r/MachineLearning is the best for research-level discussion. For learning, r/learnmachinelearning is the best starting point.

Where should beginners ask machine learning questions?

r/learnmachinelearning and r/MLQuestions. r/MachineLearning restricts beginner questions to a weekly thread.

Is there a subreddit for ML engineering and deployment?

r/mlops covers production ML, and r/datascience covers applied industry work.

Can I take over an inactive machine learning subreddit?

Yes. Subreddits for specific frameworks, courses, and older techniques are often abandoned. If every human mod has been inactive for 60+ days, request the community through r/redditrequest. DeadSubs can find ML communities with inactive moderators.
