The explanations of supervised vs unsupervised learning finally clicked for me, though I wanted more hands-on coding exercises.

Conceitos de machine learning bem explicados.

Die Grundlagen zu Entscheidungsbäumen und Regression waren gut aufbereitet, auch wenn mir am Ende ein größeres Praxisprojekt gefehlt hat.

بدأت هذه الدورة وأنا لا أعرف الفرق بين التعلّم المُوجَّه وغير المُوجَّه، والآن صرت أفهم الفكرة الأساسية وراء كل نوع. أعجبني كثيرًا أن المفاهيم النظرية ترتبط دائمًا بتطبيقات عملية، فلم تبدُ المادة مجرّدة أو مملّة. الشرح حول كيفية تعلّم النموذج من البيانات وتقييم أدائه كان واضحًا ومنطقيًا. خرجت من الدورة بفهم حقيقي يكفي للبدء في بناء أنظمة ذكية بسيطة وتحليل البيانات بثقة. أنصح بها كل من يريد مدخلًا متينًا إلى تعلّم الآلة.

อธิบายแนวคิดหลักของ machine learning ได้เข้าใจง่ายและมีตัวอย่างการใช้งานจริงประกอบ ทำให้เห็นภาพว่าโมเดลเรียนรู้จากข้อมูลอย่างไร อยากให้ลงลึกเรื่องการประเมินผลโมเดลมากกว่านี้อีกนิด แต่โดยรวมเป็นจุดเริ่มต้นที่ดีมากครับ
