AI Exam 5 - AI Aspects

AI Practitioner Exam Prep Aspects of AI Cost Considerations   Cost factors are responsiveness and availability, redundancy and regional coverage, performance, token-based pricing, provisioned throughput, and refining your custom models. Responsible AI Aspects: controllability, explainability, fairness, governance, interpretability\transparency, privacy\security (theft and exposure risk), safety, and veracity\robustness.   Business Benefits: trust, regulatory complain, mitigate risks, competitive advantage, improved decision making, and improved products.    Model Selection: a)  Narrow the use case so you can tune your model to your use case.  Ex: favor recall or precision , b) pick by performance with some test data sets,  c) responsible agency, d) environmental reasons, e) economical reasons.   Dataset Prep: want  balanced dataset  so  inclusive and diverse  in data collection, curating by 1) preprocessing, 2) augmentat...

AI and Genie

AI and Genie copyrighted by Eric Wood in 2026   You rub an old lamp you find and out comes a genie called "AI".  "AI" says he will grant 3 wishes.      1) Your first wish is for a grand house. You don't see the results. Genie says it will be done in 100 years since you did not specify when.       2) Your second wish is to live 100 years later. You seeing flying cars, etc. but no house. You don't see the results. Genie points out that house is microscopic since you did not specify size.    3) Your third wish is to be microscopic. So you enter the house and see that the house is fabulous. Then the cow steps on the house crushing it and kills you. Genie says I probably would have specified that the house is to be indestructible.
