What is Yolo and how it works?
YOLO stands for You Only Look Once. It’s an object detector that uses features learned by a deep convolutional neural network to detect an object. The main core concept of YOLO is to use a single neural network to predict bounding boxes and class probabilities directly from full images in one evaluation.

If the original sender decides to respond, their reply is in turn posted back to Snapchat. Is Yolo a good app?
What is YOLO you only live once?
YOLO stands for You Only Live Once. YOLO trades are where you go all in to make a big return. You can see a share price rising in premarket trading and then decide to buy it as soon as the market opens. When a M&A deal is announced, the initial response is for the stock price of the company to go up and for the other party to go down.
What does Yolo really mean?
YOLO means "You Only Live Once" (you only live once). It is an acronym that is often used as a hashtag (#YOLO) on Facebook, on Instagram and in some memes.
