To alleviate the limitation mentioned above, we propose a Reading-strategy Inspired Visual Representation Learning (RIVRL) model. We are inspired by the reading strategy of humans, where humans typically preview text with a quick glance to obtain an overview of the text, and then intensively read it with the text overview to gain a deeper understanding. Our hypothesis is that if one model first briefly knows the video overview, it will help the model understand the video more deeply. Therefore, our proposed video representation model consists of two branches: a previewing branch and an intensive-reading branch, as illustrated in Fig 1 (c). The previewing branch is implemented as a lightweight video encoder, which is designed to briefly capture the overview information of videos. By contrast, the intensive-reading branch is implemented as a relatively heavy video encoder, which is designed to obtain more in-depth information. The key point is that the earlier generated representation from the previewing branch is then integrated into the representation learning of the intensive-reading branch.|A hatchling Rapetosaurus as compared to newborn mammals. Babies! They're so cute! And one thing we find so endearing about our own offspring is how different they look from us as adults. But while human babies have different proportions than adults of our species, that's not the case for all animals. Think of baby horses, for instance, on their feet and tottering around within a few hours birth. Though a foals is not exactly a perfect match for an adult, it's pretty darn close. And now new research shows that the largest dinosaurs that ever lived also hatched with similar proportions, shedding life on the different ways dinosaurs evolved to live and socialize. New fossil analysis published today in the journal Science shows that hatchling titanosaurs came out of the egg with proportions very close to what they'd have when full grown. Researchers examined fossils of the titanosaur Rapetosaurus krausei, which was not the largest of the titanosaurs, the largest land animals that we know of, but could still grow to 50 feet (15 meters) in length and weigh about the same as a modern-day elephant. An electronic cigarette doesn't rely on this process of combustion. Instead, it heats a nicotine liquid and converts the liquid to a vapor, or mist, that the user inhales. Depending on the e-cigarette, the user may simply inhale from the cartridge to begin the vaporization process, though some devices have a manual switch that activates the vaporizer inside. The charged battery is connected to the vaporization chamber, a hollow tube that contains electronic controls and an atomizer -- the component that creates the vapor. Before the user activates the device, he or she attaches a cartridge containing nicotine liquid to the vaporization chamber. The tip of the cartridge serves as the e-cigarette's mouthpiece. E-cigarette users inhale the way they would with a regular cigarette. This inhalation activates the atomizer to heat the liquid in the cartridge and convert the liquid to a vapor. Inhaling this vapor through the mouthpiece delivers nicotine to the lungs, and the user exhales vapor that looks much like a cloud of cigarette smoke. casos de coronavirus en el mundo
