Optimizing Multiple Loss Functions with Loss-Conditional Training

ایده ی جالب این مقاله اینه که برای برخی از کاربردها نظیر style transfer و یا image compression و یا ... که چند تا loss مختلف داریم، قبلا مجبور بودیم ضریب هر loss را تعیین کنیم و بعد آموزش بدیم و این ضریب روی خروجی تاثیر داشت.
مثلا در بحث image compression ممکن بود تنظیم این ضریب روی کیفیت عکس و حجم اثر بزاره، مثلا در یک طرف کیفیت بالا و حجم بالا و در طرف مقابل کیفیت پایین و حجم پایین
حالا فکر کنید اگر شبکه عصبی برای کاهش حجم عکس در 3 حالت مختلف ( خیلی کاهش حجم - متوسط - کاهش حجم کم) میخواستیم باید 3 شبکه آموزش میدادیم و ذخیره میکردیم.

در این مقاله گفته فقط یک شبکه ترین کنیم و پارامترهای اینچنینی را بعد از آموزش روش کنترل داشته باشیم.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
