یک روش میانه وزن دار برای تجزیه ماتریس رتبه پایین L1 در حضور داده های پرت و از دست رفته
خلاصه:
یک مشکل در یادگیری ماشین ، ذخیره اطلاعات و مساله بینایی ماشین بوده که چگونگی بازیابی را با رتبه پایین داده ها در حضور داده های پرت و از دست رفته نمایش می دهد. تجزیه ماتریس رتبه پایین نرم (L1 (LRMF برای حل این مشکل به کار رفته است. با توجه به اینکه نرم L1 برای بدست آوردن حالت های غیر محدب و غیر صافی دردساز بوده و چنین روش ها اغلب در همگرایی به یک مقدار مطلوب به مشکل بر می خورند لذا در این مقاله از یک روش جدید میانگین وزن دار (Cyclic weighted median) یا (cwm) برای نرم L1 استفاده نموده ایم. روش CWM توابع هدف را با زیر مساله های کمینه ساز عددی حل کرده که غالبا محدب شده و می تواند به سادگی با فیلتر میانگین وزن دار حل شود. نتایج شبیه سازی نشان می دهد که روش cWM در حالت های از دقت و کارآیی محاسباتی ، بهتر عمل می کند. برای فهم دیگر اطلاعات این شبیه سازی ، مقاله را از لینک زیر دانلود نمایید.
