2), the distances between anchor-positive and anchor-negative pairs are used for discriminative feature learning. However, in knowledge distillation, the outputs of two networks are heterogeneous, the absolute distances between these pairs are not well aligned. In order to mitigate the misalignment, we propose to measure the probability of the two distances. POSTSUBSCRIPT measures how much the anchor is closer to the positive than the negative. POSTSUBSCRIPT is large, otherwise it is small. POSTSUBSCRIPT brings higher order (third order) similarity comparison, encoding the structural information in the triplet. MDKT can better learn discriminative features even without the classification loss. In the test stage, each query is a static image and the gallery set consists of video clips. In our work, one single network is used for both image and video feature extraction. Herein, we treat the still image as a video. After feature extraction, the distances between the query feature and each gallery video features are calculated and the I2V retrieval is conducted according to the distances.|Former US president Donald Trump has called Russian president Vladimir Putin a “genius” for his decision to recognise the two self-proclaimed republics in Luhansk and Donetsk of Ukraine and deploy troops into the Russian-controlled territory. This is genius Putin declares a big portion of the Ukraine - of Ukraine. Putin declares it as independent. So, Putin is now saying, ‘It’s independent,’ a large section of Ukraine. I said, ‘How smart is that? Here’s a guy who’s very savvy… I know him very well. Trump accused Joe Biden of being “weak” in his response to Putin, adding that it “never would have happened” if he were still president. By the way, this never would have happened with us. Had I been in office, not even thinkable. I think he sees this opportunity. I knew that he always wanted Ukraine. I used to talk to him about it. I said, ‘You can’t do it. You’re not gonna do it.’ But I could see that he wanted it. I used to ask him. As a result, Caterpillar employs the single- or dual-camera system in place of a rearview mirror, which isn't feasible in such a large vehicle. These trucks have dump beds blocking all rear visibility, much as a camper shell obstructs the rear view in a pickup truck. Auto manufacturers have followed the lead of construction and mining equipment companies and now offer rearview cameras similar to the one seen on the Infiniti EX35. While Infiniti's AVM system boasts a 360-degree view, most rearview cameras found in the auto industry display only what's behind the vehicle. Just about every manufacturer, from Lexus to Chevrolet to Dodge with the iconic Caravan, offers a rearview camera system on one or more of their vehicles. Several other safety features complement rearview cameras, such as backup sensors, which sound off with proximity alarms. Have you ever been sitting at home. Heard a truck beeping as it backed up? Those are backup alarms alerting people outside the vehicle.|“Let’s do this without chaos. Calm down!” urged one driver standing in front of a large white bus headed for the city of Lviv. A river of red taillights stretched for miles along the road that leads west to Lviv, and eventually, Poland. Roman Timofeyev, who was standing with four friends in Kyiv’s main bus station and trying to get on a bus, said he was trying to reach Lviv and then Poland. He said he had packed clothes, documents and medicine for the trip. He and his friends planned to go to Turkey for a few weeks to wait out whatever might happen. “Wait for the end of war, and then come back,” he said. A young man in gray sweatpants and black hat sat looking stunned on a small black duffle bag next to a long line of prospective bus passengers. He said he was waiting for a bus west. “Horrible,” said the man, who gave only his first name, Alexander, and said he was 18. “Our people, our military are now dying in the Luhansk and Donetsk regions, and it’s horrible. yolo meaning
