Youtube blir bättre på att hitta tumnaglar till videor
Tack vare maskininlärning

Dina Youtube-videor kommer i framtiden få betydligt bättre tumnaglar än tidigare, så att du slipper lägga till bra och lockande bild på egen hand. Detta tack vare ett nytt system som använder sig utav maskininlärning för att hitta den perfekta bilden. På Googles utvecklingsblogg skriver gänget om hur detta går till och nedan kan ni se ett utdrag av blogginlägget:
Unlike the task of identifying if a video contains your favorite animal, judging the visual quality of a video frame can be very subjective - people often have very different opinions and preferences when selecting frames as video thumbnails. Fortunately, on YouTube, in addition to having algorithmically generated thumbnails, many YouTube videos also come with carefully designed custom thumbnails uploaded by creators. Those thumbnails are typically well framed, in-focus, and center on a specific subject (e.g. the main character in the video). We consider these custom thumbnails from popular videos as positive (high-quality) examples, and randomly selected video frames as negative (low-quality) examples.Denna nya algoritm har redan implementerats på Youtube nu och laddar du upp en video så kan ni se den nya algoritmen in action. Här nere till vänster hittar ni hela inlägget om Youtubes maskininlärning.
