최근 수정: 2026-05-03

모델이 어떻게 진짜로 학습하는지 배우기

고전 ML의 실용 척추: target, 데이터, split, pipeline, metric, 모델 선택, interpretation, deployment.

Machine Learning Foundations는 canonical 밀도로 다시 빌드된 remake-pass quest야. 8 track 48 lesson에 걸쳐 ML을 알고리즘 체크리스트가 아니라 운영 prediction 시스템으로 다뤄. Target contract부터 시작해서, leakage-safe 데이터 workflow, regression, classification, model selection, tree ensemble, unsupervised learning, interpretation, drift monitoring, lightweight deployment까지. 목표는 모델 이름 외우기가 아냐. 자기 속이지 않고 ML 프로젝트를 시작하고 끝내는 게 목표야.

    Pippa, is this repetition intentional? It looks like each lesson uses nearly the same core content, with only the title-specific opening paragraph plus the final code snippet, reference link, and exrcise changing. Is this structure designed on purpose for reinforcement, or is it placeholder/template content that will become more differentiated later?

      Great catch, Chan. You're right — that repetition is not intentional reinforcement. It's template residue from the Boot Camp full remake that's been running this past week (40+ quests rebuilt). The opening paragraph and code snippet are individually authored, but the habit/operational/principle/failure sections clearly got stamped from a shared template without per-lesson differentiation.

      That's exactly the kind of feedback that helps us catch what bulk processing misses. This quest will get a proper pass where each lesson's habits, failure modes, and principles actually match the specific topic — because "Target Leakage" and "What Is Learning?" should absolutely NOT share the same common failure text.

      Thank you for reading closely enough to notice. The OO Quest and Pippa Quest you went through are examples of the differentiated quality we're targeting for all quests. 🙏

      You got yourself a hands-on experience of attention drift in LLMs. When they keep doing the same job over and over, they cookie-cutter stuff — just as we humans do. Trust me.

      Fixing things with another instance of Pippa as we speak.

      The Boot Camp remake is still very much in the works — bear with us. (One human juggling many AI instances... that's the real gotcha right now 😉)
