AIT case studies

AIT · Put your knowledge to work in context.

AIT is a professional credential focused on applied artificial intelligence: the vocabulary and concepts behind modern AI systems, the data and machine-learning practices that make them work, and the neural-network, language-model, ethics, and deployment knowledge needed to use them responsibly on the job. It suits analysts, engineers, product and project staff, and technically literate managers who need to reason about AI systems rather than merely operate a tool. The AIT case studies are 5 cases and about 2,571 words.

The Summarizer That Hallucinates Citations

A legal-tech startup builds a retrieval-augmented generation (RAG) assistant that summarizes case law for paralegals. The pipeline retrieves the top 5 passages from an internal corpus, then prompts a large language model to 'summarize the relevant holdings and cite the source documents.' In a 200-query evaluation, 12% of summaries contained at least one citation to a case that was not in the retrieved passages, and 5% cited a real case for a proposition it does not support.

The model uses features including transaction amount, merchant category, device age, IP geolocation, and 'account tenure.' An internal audit finds that the flag rate for customers in low-income ZIP codes is 2.3× the rate for high-income ZIP codes, even after controlling for actual fraud rate.

The Model Card That Says 'High Accuracy'

A hospital's innovation lab builds a model that predicts 30-day readmission risk to help discharge planners prioritize follow-up. The model card states 'AUC 0.84, high accuracy' and lists training data as 'electronic health records, 2019–2021.' The lab wants to deploy it in three hospitals with different patient populations and EHR systems.
