This chapter explains how to write AI papers that reviewers can understand quickly and trust. It treats writing as part of research, not a final packaging step, and shows how early planning clarifies the problem, contribution, and experiments before drafting begins. It then walks through writing around the research problem, using each paper section to move readers from motivation to method to evidence. The chapter emphasizes narrative coherence, precise claims, and consistent terminology and notation. It also gives guidance on revising with feedback and responding to reviewer critiques in rebuttals with a professional, evidence-focused tone.
