هو تقنية إحصائية في التعلم الآلي لتقليل كمية المتغيرات العشوائية في المشكلة من خلال الحصول على مجموعة من المتغيرات الرئيسية. يمكن تنفيذ هذه العملية باستخدام عدة طرق تبسط نمذجة المشكلات المعقدة، وتزيل التكرار وتقلل من الإفراط في المواءمة وبالتالي تقليل تضمين النتائج التي لا تنتمي لمجموعة النتائج الصحيحة.
هناك طريقتان لتطبيق تقنية تخفيض الأبعاد، وهما:
إليك بعض مزايا تطبيق تقنية الحد من الأبعاد على مجموعة البيانات:
