Research Methods in CS

How to read papers, run experiments and publish.

How it works

Research in computer science follows a cycle of asking a question, reviewing related work, proposing a method, evaluating it and publishing. Reading papers efficiently means scanning the abstract, introduction and conclusions first, then the method and results, and following citations. Experiments need clear hypotheses, baselines, fair datasets, repeated runs with statistics such as confidence intervals and ablation studies. Theory papers give proofs, systems papers show implementations and measurements and human studies need ethics approval. Results are published at peer-reviewed conferences and journals, shared as preprints on arXiv, and supported by code and data for reproducibility.

Where it is used

Students and engineers use these methods in theses, internships, industry research and when judging claims in technical articles.

Common pitfall

Cherry-picked results, weak baselines, test set leakage and unreported failures mislead, and citing without reading spreads errors. Report negative results, release code and compare against strong, fair baselines.

Where it fits in the course
