Common Flairs

[D] Discussion[R] Research[P] Project[N] News[Tutorial]

Who's Here

ML researchers, data scientists, AI engineers, and PhD students. Highly technical. Many work at top tech companies or research labs. Expect depth and rigor in technical discussions.

Common Mistakes on r/MachineLearning

Avoid these pitfalls that get marketers banned or ignored.

AI hype without substance

The community sees through marketing. "Revolutionary AI" claims without technical backing get dismissed or mocked.

Instead

Be specific: "Achieved [metric] on [benchmark]. Methodology: [approach]. Limitations: [list]."

Ignoring existing research

ML moves fast but builds on prior work. Claims of novelty without citing related work suggest unfamiliarity with the field.

Instead

Position in context: "Builds on [paper]. Key difference: [innovation]. Compared to [baseline]: [results]."

Closed-source without justification

The community values open science. Proprietary models without shared methodology face skepticism.

Instead

Share what you can: "Model weights at [link]. Training code coming. Paper with methodology: [link]."

Beginner questions in main subreddit

r/MachineLearning is for substantive discussion. Beginner questions belong in r/learnmachinelearning.

Instead

For learning questions, use r/learnmachinelearning. For main posts, bring research or production insights.

Overstating benchmark results

The community will scrutinize methodology. Cherry-picked benchmarks or unfair comparisons get called out.

Instead

Be thorough: "SOTA on [benchmark]. Slightly worse on [other benchmark]. Compute requirements: [details]."

Post Formats That Work on r/MachineLearning

These content formats consistently perform well in this community.

Research Discussion [D]

Example Format

""[D] [Paper title]: Summary of key contributions, methodology, and results. Discussion points: [questions]. Paper: [link].""

Why It Works

Proper flair. Summary helps accessibility. Questions encourage discussion. Link to source.

Project Announcement [P]

Why It Works

Clear project scope. Technical details. Benchmarks. Open-source code.

Production Case Study

Example Format

""Deployed [model] at scale. Architecture: [approach]. Challenges: [list]. Learnings: [insights]. [Company context if applicable].""

Why It Works

Real production experience. Honest about challenges. Practical insights.
