Author Miao Jian Research Institute

May is an important period for the automobile market. Many new cars exhibited at the Shanghai Auto Show began to appear on the market one after another. Joint-venture brands and independent brands are competing to launch brand-new, mid-term and annual models, bringing more choices to consumers. This also makes the domestic auto market more exciting and interesting.

According to the statistics of Miaojian Information Public Opinion Monitoring Platform, in the TOP10 public opinion hot list of new cars listed in May, domestic brands dominated, and among the new cars listed, fuel/plug-in models accounted for over 60%.

40% of the new models were launched in this month’s list, mainly medium and large SUVs. Among them, the price is divided into multiple grades, the highest is 389,800 yuan (Chuanqi E9) and the lowest is 79,800 yuan (Baojun Yueye).

In the list, the old best-selling models Accord and LaCrosse are all replacement models. Small and medium-term models are all plug-in models except Seal, which is pure electric.

01

List of new cars on the market: the new Haval Xiaolong won the No.1 new car communication in May, and BYD dominated the list of three models.

Haval Xiaolong (brand new) is the model with the highest heat index this month. On May 15th, the launch conference of Haval brand new energy night and Haval Xiaolong series was successfully held in Beijing, officially releasing the brand new energy strategy of Haval brand and launching a brand new energy product-Haval Xiaolong series, with the starting price of new cars ranging from 139,800 to 179,800 yuan.

Nearly 6.5% of Haval Xiaolong’s sound volume is generated at the client. Know the car emperor, today’s headlines and Sina Weibo are the main communication channels, among which Weibo has 91,000 interactive voices, which is the second highest interactive car in this month’s list. "Intelligent four-wheel drive" and "travel audio-visual room" are the main communication points of Haval Xiaolong.

There were many hot spots in the launch of Haval Xiaolong. In addition to the introduction of new cars, Feng Mu, president of Great Wall Motor, launched the "Five Questions of the Soul" on the spot. In addition to expounding the current situation of China’s automobile market and the development prospect of Haval brand, Feng Mu also pointed out the bad practices of disrupting the market, such as friends raising the water army and worrying product quality, saying that some car companies regard "controlling public opinion as the primary productivity" and even commented that some car companies "won sales and lost the bottom line"

Guangqi Honda Accord (replacement) is another popular model this month, which was officially launched on May 20th. As an old-fashioned best-selling model, the new car was widely discussed and paid attention to during the listing period, and "brand-new" and "intelligence" were the main communication points.

Guangzhou Automobile Chuanqi brand continues to maintain the new strength and communication potential of "new cars every month".

During the listing of Chuanqi E9, Guangzhou Automobile Chuanqi 4S stores all over the country, with today’s headlines, knowing the car emperor and car home as the main positions, made a lot of momentum. The marketing text is short, matched with key words of product characteristics, emphasizing electricity and oil, four-fold luxury gifts and so on. Reflect saving and highlight preferential treatment.

　　At 22: 00 on August 14th, Hualong. com (special correspondent Luo Hao) On August 14th, more than 50 online media reporters from the northern line of Ningxia, a national online media, came to Ningxia Rice and Fishery Space Ecological Leisure Sightseeing Park in Sishilidian Village, Changxin Township, Helan County, Yinchuan City after finishing the interview in Shizuishan City.

　　When I got off the bus, a neat piece of rice fields came into view, followed the steps to the observation tower in the garden, climbed high and looked far, and the pastoral scenery of full of green was panoramic. Different varieties of colored rice also made the online media reporter shout, "No wonder Yinchuan has ‘ Plug in the land of fish and rice in the south of the Yangtze River ’ The reputation of ".

　　In 2016, Shilidian Village, Changxin Township, Helan County established Guangyin Rice Industry, Rice and Fishery Ecological Industry Sightseeing Park. In 2017, a rice fishing space was established, covering a total area of more than 3,600 mu.

　　The rice and fishing space makes full use of agricultural and environmental resources, and builds a Yellow River Jin ‘an leisure agriculture industry demonstration base which integrates organic rice characteristic ecological agricultural production, fishery breeding, catering and fishing, sightseeing, leisure and entertainment, wedding photography, organic agricultural product processing, e-commerce sales and farmers’ training.

　　"It’s not that I boast, we are really a leisure tour in Yinchuan metropolitan area ‘ Online celebrity ’ Point, it became a fire as soon as it was established last year, and a large number of tourists flocked to this piece of land with paper and rice and grass as pigments ‘ Painting ’ An idyllic complex. " Zhao Jianwen, the person in charge of the rice and fish space, said, "This place is not only suitable for gathering relatives and friends, but also suitable for bringing children to play. Children like to touch fish and pick up duck eggs in rice fields very much. According to statistics, in 2017, the rice fishing space received a total of 190,000 tourists, and it reached 150,000 in the first half of this year.

　　Rice and Fishing Space has also conducted all-round training for leisure and organic agriculture practitioners, and radiation has driven 500 farmers to become rich.

　　The innovation of the spatial pattern of rice and fishery is not only a beneficial exploration of the pilot work of the integration of the three industries in Helan County in recent years, but also provides important technical support and demonstration for the economic development of "agriculture+tourism" in the whole region. In recent years, leisure agriculture and rural tourism in Ningxia have developed rapidly, with nearly 900 related business entities, benefiting 170,000 farmers.

　　Ai growing pains

　　Editor’s note In recent years, artificial intelligence has developed rapidly and its application fields have been expanding. However, at the same time, AI "rollover" cases are frequently searched. Based on this, this edition opens the column "AI Growing Pains" to focus on AI "rollover" events, analyze the phenomenon, analyze the reasons, explore the solutions, and look forward to its growth.

　　Intern reporter Dai Xiaopei

　　After the game, it is probably unprecedented for fans to ask referees to wear hats or wigs.

　　At the end of October, Scottish fans experienced an "unforgettable" football match. In the Scottish Football Champions League match between Furness and Elven, the AI cameras on the sidelines turned a blind eye to whether the players passed the ball or attacked with the ball. Instead, they followed a linesman and took a close-up of "C position" from time to time. It turned out that the AI camera mistakenly identified the referee’s bald head as a football, so he chased the whole game crazily.

　　Fans who watched the 90-minute game at home spent most of their time not watching the ball, but watching the bald heads. Many netizens joked that this game really "saw a loneliness".

　　Why does the AI camera regard the bald head as a football? What do we need to do to prevent AI from making similar mistakes? Can you think that AI is "weak" when there is a "rollover" incident?

　　Unconscious "provocation" from bald referees

　　From direct participation in sports events to recording athletes’ performance, to live broadcast of competitions and analysis of athletes’ health status, AI is becoming the darling of the sports world. A few months ago, Barcelona Football Club (Barcelona) also joined hands with video technology company Pixellot to create an artificial intelligence coaching solution.

　　Unexpectedly, AI, which has made great strides in sports, unexpectedly encountered an unconscious "provocation" from a bald linesman. Because the linesman’s bald head is too bright and the sun shines, the AI camera can’t tell which is the ball and which is the head. Previously, because the Furness team said that the AI tracking technology they used could clearly transmit the live images to the homes of every season ticket buyer, so that fans who could not go to the home due to the COVID-19 epidemic would not miss any game.

　　It is reported that the camera used in the live broadcast of this competition is the multi-camera system provided by Pixellot, which cooperates with Barcelona. The system is powered by NVIDIA’s graphics processor (NVIDIA GPU), and the captured video resolution can reach 8K. These cameras can be installed in a fixed position without being manipulated by the camera operator. In order to capture the key moments, Pixellot collected hundreds of thousands of hours of sports videos to train its algorithm on the NVIDIA GPU of the local workstation.

　　With a huge amount of available data, using deep learning algorithms and high-performance GPU computing blessing, it has three major driving forces to push AI forward. Why did Pixellot’s AI camera "roll over"?

　　After the event, the relevant clubs and the technology companies that make cameras reflected. The problem seems very clear: the size and shape of football are similar to those of a human head, and the direct sunlight makes the AI camera fall into "confusion". I hope this will not happen again, because the Furness team responded that it knew the problem and will improve the next game to bring a better experience to the audience.

　　Pixellot also said that it is not difficult to solve this problem. The existing target detection and tracking technology is mature. Pixellot didn’t consider the influence of bald head in the design stage, so it needs to collect some data of football and bald head to fine-tune the algorithm to eliminate the interference from bald head.

　　Some technicians said that not only "this is a ball" data set, but also a "this is not a ball" data set is needed when training the AI camera of the live ball game. Bald head, bright white shoes, lighting, balls on the training ground next to the competition field and balls used by players to warm up are all interference factors that need to be considered when training AI.

　　AI "poor eyesight" is the norm.

　　Although the performance of AI cameras can be improved by increasing data "feeding", strengthening training and improving algorithms, some professionals believe that with the gradual expansion of AI application scenarios, such "rollover" incidents will exist for a long time.

　　“AI‘ Rollover ’ It’s normal, no ‘ Rollover ’ It’s strange. " Professor eecs and Huang Tiejun, president of Beijing Zhiyuan Artificial Intelligence Research Institute, spoke frankly when interviewed by Science and Technology Daily reporter.

　　Huang Tiejun believes that on the surface, the failure of the AI ? ? camera may be due to insufficient pre-training, but the main reason is that the current computer identification system is only trained with specific data. For example, in the above example, the neural network trained with a large number of football videos has surpassed humans in identifying football, but it ignores that this network is more sensitive to bald heads.

　　It is common to recognize or "turn a blind eye" unknown objects at random.

　　Machine vision is to endow the machine with visual perception, so that the machine has the scene perception ability similar to that of biological vision system, which involves optical imaging, image processing, analysis and recognition, execution and other components.

　　"Take the camera as AI ‘ Eyes ’ In real scenes, there is still a long way to go for AI to recognize football and baldness like human eyes. " Huang Tiejun said.

　　When can I finish this road and even realize that the eye of AI surpasses the human eye?

　　It depends on when machine vision will bridge the gap with biological vision. "The brain in the skull senses the outside world in real time through more than 3 million nerve fibers, of which there are more than 1 million behind each eye." Huang Tiejun said, "The machine vision developed to this day is still a drop in the bucket compared with the biological vision system that took hundreds of millions of years to evolve."

　　The human eye has strong adaptability, can identify targets in complex and changing environments, has advanced intelligence, and can use logical analysis and reasoning ability to identify changing targets and summarize laws. On the other hand, machine vision can use artificial intelligence neural network technology, but it can’t identify the changing target well. Due to the constraints of hardware conditions, the current general image acquisition system has poor color resolution.

　　"Compared with biological visual neural networks, the visual neural networks of artificial intelligence are far apart in structure and scale, so their functions are much worse." Huang Tiejun said, "In real applications, machine vision ‘ Rollover ’ It is not an accident. It is only a case to identify the bald head as a football. Similar problems actually exist in large numbers. "

　　Huang Tiejun said: "This time, the technology provider can make up for the loophole that the bald head mistakenly thinks of football, but there are still more loopholes. Deceiving the face recognition system with antagonistic picture training is only the tip of the iceberg."

　　Different technical routes are racing.

　　"Machine vision based on deep learning has made great progress in image recognition, but it has not really solved the perception problem." Huang Tiejun believes that deep learning is far from grasping the complexity of human visual system.

　　Deep learning is based on the training of image and video big data, which is far from the biological vision that actively perceives the dynamic world, and it is still not out of demand for computing power. For example, if the video frame rate is increased from 30 to 30,000, the computing power of deep learning needs to be increased by 1,000 times.

　　Biological neural network is a pulse neural network, which is more suitable for completing visual information processing. Huang Tiejun believes that learning from the neural network structure and information processing mechanism of biological vision system and establishing a new set of brain-like vision information processing theory and technology is the hope of restarting machine vision.

　　Experts said that there are two main technical routes to develop artificial machine vision. One is to build a powerful intelligent system by collecting more data, increasing the amount of data and strengthening training; The second is to imitate the biological nervous system, follow the gourd painting gourd ladle, clarify the structure and even mechanism of the biological nervous system, and develop future intelligence on this basis.

　　Huang Tiejun believes that the second path is more effective than the first one. "In a short time, the first one is easier to achieve results. But in the long run, it is more direct to start with biological neural networks and more confident to achieve the goal. "

　　At present, most AI scholars support the first path, that is, to develop artificial intelligence including machine vision through "big data+big computing power". Huang Tiejun set foot on the road taken by a few people because he firmly believed that the biological visual neural network had great potential to be tapped. "Biological brain is the product of hundreds of millions of years of evolution, and it is the best transcendental structure. Powerful intelligence must rely on complex structures and stand on the shoulders of evolution. It seems difficult, but it is the fastest. "

　　Turing, the "father of computer science", has long expressed his admiration for the biological brain. At the beginning of 1943, Shannon suggested that "cultural things" could be instilled in the electronic brain. Turing once retorted in public: "No, I’m not interested in building a powerful brain. What I want is just an ordinary brain, just like the head of the chairman of AT&T."

　　Is developing machine vision, or artificial intelligence, starting from scratch, imitating biological neural networks, or is there another way? There is no conclusion yet. On different tracks, artificial intelligence is accelerating.

　　Although there are many cases of AI "rollover", such as the practicability of Google AI eye disease diagnosis system is greatly reduced in Thailand, Tencent AI translation made a joke at the Boao Forum in 2018. But the AI era is accelerating and unstoppable.

　　"It must be admitted that AI has indeed solved many practical problems, and it will gradually replace some functions of people. But we can’t exaggerate it too much. It is still far from our imaginary intelligence and needs more breakthroughs. " Huang Tiejun said that to keep an open mind and bridge the gap between "experimental simulation" and "real world", the development of AI technology has a long way to go.

　　The scenery of Dahe Town in Tongzi County. Photo by Cheng Yong

　　After a night of spring rain, Shan Ye, who had been sleeping for the whole winter, gradually stretched out. In the Dalou Mountain Range, spring is gradually sprouting in the mountains. On both sides of the road, there are peach blossoms, plum blossoms, camellia and rape blossoms … … The colors are intertwined with the green hills, just like a beautiful picture.

　　We went to shi niu cun, Dahe Town, Tongzi County, Guizhou Province, to visit the 80-year-old afforestation model Weifafu. Starting from the county seat, the sky is already dawn. The car passed through the thick morning fog, passed the famous 72-way turn, and entered shi niu cun eastward. More than 300,000 Chinese fir trees planted by the Weifafu family grew on Daping Mountain at an altitude of more than 1,000 meters. The sun gradually dispels the morning fog. In the distance, the vast forest of Daping Mountain is as clean and green as washed in the spring sunshine.

　　Along the mountain road, we walked into a green ocean. In the forest, the air is particularly fresh and cool, and the smell of flowers, trees and soil is everywhere. On a hillside, the old man in Weifafu was seen leaning over to pick up garbage in the forest with a bamboo basket on his back. When the old man saw us, he stopped what he was doing and came to shake hands with us with a smile. The old man is in high spirits and energetic, with a faint dew on his gray hair and grass clippings on his rubber shoes. His palm is wide and rough, with thick calluses.

　　The sun shines obliquely on the straight fir trees from high places through the dense forest. A few birds are jumping on clusters of new leaves, twittering the news of spring.

　　"You see, the tree, the bird came. When birds come, there are fewer insects. Bird droppings are rich in soil and trees are growing well. " The old man touched a stout fir tree and said happily.

　　"Did you plant all these trees?"

　　"More than that, there are more than 1,100 mu." The old man led us to a high place and pointed to the mountains in the distance: "These mountains are the farthest. If you walk, it will take a whole day to get there."

　　I looked up and couldn’t see the farthest hill. It’s hard to imagine how hard it took Wei Fafu’s family to plant small saplings into today’s towering trees by shouldering their backs and walking dozens of miles of mountain roads.

　　Speaking of afforestation, Wei Fafu has a lot to say. In 1950s and 1960s, due to excessive reclamation, the ecological environment of Daping Mountain was worrying. At that time, Wei Fafu often wandered alone on the mountain, looking at the barren mountain, listening to the mountain wind raging on the bare mountain, rolling up the dust all over the sky, and his heart seemed to be tightly pulled.

　　In the spring of 1985, Wei Fafu, then the production team leader, decided to return the sloping farmland to plant trees. His decision was supported by his family. He applied to the village collective for contracting, signed a contract for greening barren hills, and received seedlings subsidized by the county forestry bureau.

　　Since then, Wei Fafu’s family began to plant trees. In order to speed up the progress, Wei Fafu raced against time like clockwork. There is only one thought in his heart: "plant a variety of trees and turn the barren hills green as soon as possible."

　　"Every day, at dawn, our family set off, and everyone was carrying hundreds of pounds of saplings. Two red marks were pulled out of the shoulders, and water bubbles were ground in a few days. The slope is steep and the road is far away. We only eat two meals a day, and the time saved is used to hurry. At the end of the day, the coat is often soaked with sweat, the pants are covered with dew, and the whole body is wet. " The old man still remembers the scene at that time.

　　However, in the first spring, because of the serious soil erosion, low soil water storage capacity and lack of experience in planting trees, the planted trees only lived for a small part. Wei Fafu rallied and ran out of water, so they carried Mizukamiyama. He works in the forest for ten hours every day, and the action of planting trees is becoming more and more skillful. He scraped the soil with one hand and held the seedlings with the other, straightened the roots and carefully put the seedlings into the pit. Fir and pine seedlings are leafy and hard, and often prick their fingers, so he uses soft ant nest soil to stop bleeding and relieve pain. In summer and autumn, he went out early and went back to the forest to pull weeds. Even in the cold winter, he still patrols the mountain forest every now and then. After a year, he has worn out more than ten pairs of shoes. This year, the survival rate of saplings was as high as 90%.

　　Speaking of the trick of planting trees, the old man smiled: "Planting trees is the same as being a man. The roots of saplings should be buried deeply and kept straight, so that they can easily take root in the earth."

　　One minute, nine in charge. In order to afforest, he opened up a 10-mu nursery, and some seedlings were self-sufficient. He also set up a brick and tile factory to exchange all the bricks produced with villagers for working hours, so as to increase the labor input for planting trees. Winter goes and spring comes, year after year. Ten years later, with the efforts of Wei Fafu, the barren hills of Daping Mountain gradually became green, and the once-cut mountain spring water was restored, which solved the problem of drinking water and irrigation for local villagers.

　　Someone once offered Wei Fafu a high price to transfer the forest, but Wei Fafu refused. He said: "for so many years, I have done it for green mountains and green rivers. Trees are my children. Trees are more important than money." In thirty-seven years, under his careful care, the mountain forest has never suffered a mountain fire. Today, the old man still insists on going to the Woods every season. The time with the tree became an indispensable part of his life.

　　His contribution is gradually known to more people. He won back the honors of Guizhou moral model and Guizhou labor model. Now he still has a wish, and that is to join the Communist Party of China (CPC) as soon as possible. In May 2021, 79-year-old Wei Fafu submitted an application for joining the Party, which is the oldest applicant in shi niu cun’s history.

　　In the distance, the breeze is Xu Lai, and the green waves are rippling in the forest. Listen, the branches and leaves rustle in the wind, as if the castle peak is greeting the old man.
