Extreme Yue 01 vs Extreme Krypton 001, who will not regret it?

These two days, Krypton went on a hot search for some reason. What is the reason? You can search for it yourself. The Krypton 001, which is owned by Krypton, is responsible for sales. With its performance in various aspects, it is indeed a worthwhile choice among more than 200,000 pure trams. Then, today, we might as well compare those endorsed by Geely and Baidu with those of Krypton 001, and see who we choose without regret.

First, let’s look at the prices of the two models. After all, when buying a car, the price will be an important factor for us to consider. The starting price of Extreme Yue 01 is 219,900 yuan, and as far as I know, there are many car purchase discounts in August, with a maximum discount of 42,000 yuan, including replacement subsidies and interest-free subsidies.

Extreme krypton 001, because the 2025 model has just been listed, the price is 259,000 yuan, and there is no relevant preferential policy at present. In comparison, it is obvious that the price of Extreme Yue 01 is closer to the people than that of Extreme Krypton 001, and the entry threshold is lower.

Secondly, when buying a car, I think whether the design of a car conforms to our vision or whether the space performance meets the needs of home use is also worth considering. In terms of design, Extreme Yue 01 and Extreme Krypton 001 are two different styles. Extreme Yue 01 is a pure electric medium and large SUV, which has a good sense of recognition and futurity in design. For example, the aesthetic design of the car robot used in the front face is easy to make people form memory points. The design of Krypton 001 is quite individual, and it feels a bit like hunting and running. Some young consumers who like sports and performance should like this design very much.

Above the space, the wheelbase of Extreme Yue 01 is 3000mm, which, together with its room occupancy rate, can reach 66.6%, and it will be particularly spacious above the space, especially in the back row. In the case of Extreme Krypton 001, the wheelbase is 3005 mm. From the data performance alone, Extreme Krypton 001 has advantages. However, in the actual experience, whether it is leg space or head space, the performance of Extreme Krypton 001 is actually not inferior to that of Extreme Krypton 001. After all, the spaciousness and broadness brought by Extreme Krypton 01 as an SUV are not available.

In addition, in terms of configuration, you may think that Extreme Yue 01 is cheaper than Extreme Krypton 001, so the configuration will naturally decrease. However, through comparison, we find that the configuration of the ultra-01 is a little less. Especially in the intelligent configuration, Extreme Yue 01 uses a 35.6-inch super-large floating integrated screen. With Qualcomm Snapdragon 8295 chip, the fluency and intelligence of human-computer interaction ability are enough to hang a number of players.

10

Moreover, on top of intelligent driving, Extreme Yue 01 also has high-order intelligent driving based on Baidu Apollo L4 autopilot. This intelligent driving system can free your feet and enjoy the charm of intelligent driving, whether at high speed or in urban areas.

11

The intelligent configuration of Krypton 001, especially the performance of car and intelligent driving, was actually spit out before, but after the new model went on the market, it was upgraded in these places. For example, in terms of intelligent driving, the Krypton 001 is equipped with the vast intelligent driving 2.0, with laser radar as standard, and some versions are equipped with two NVIDIA Drive Orin chips. Unfortunately, the Mobieye chip is still used in the entry-level model.

In terms of battery life, the extremely long battery life version with a guide price of 249,900 yuan can reach 720 kilometers; The entry-level version of Krypton 001, which costs more than 10,000 yuan, also has a battery life of 722 kilometers. Moreover, in terms of batteries, the former uses a more solid battery life in winter. In this way, the price/performance ratio of Extreme Yue 01 is indeed more in place.

15

Through the above comparison, we find that the starting price of Extreme Yue 01 is relatively close to the people, and it also has the same performance as Extreme Krypton 001, especially in terms of intelligence, space and endurance. After this comparison, it is obvious that the cost-effective advantage of Extreme Yue 01 is more sufficient, and it is clear at a glance who is more cost-effective.

Paper 5: reverse engineering self-supervised learning

Authors: Ido Ben-Shaul et al.

Paper link: https://arxiv.org/abs/2305.15614v2

Self-supervised learning can use the unsupervised data of auxiliary tasks to mine its own supervision information, and train the network through this constructed supervision information, so as to learn valuable representations for downstream tasks. Recently, many researchers, including Yann LeCun, winner of Turing Prize, published a study, claiming that self-supervised learning was reverse-engineered, so that we could understand the internal behavior of its training process.

In order to intuitively understand SSL training, Figure 1 below shows the embedding space of training samples of the network through UMAP visualization, which includes the situation before and after training and is divided into different levels.

Recommendation: New research achievement of Yann LeCun team: For self-supervised learning reverse engineering, the original clustering is realized in this way.

Paper 6: video composer: comprehensive video synthesis with motion controllability

Authors: Xiang Wang et al

Paper link: https://arxiv.org/abs/2306.02018

Abstract: In the field of AI painting, Composer proposed by Ali and ControlNet proposed by Stanford led the theoretical development of controllable image generation. However, the exploration of controllable video generation in the industry is still in a relatively blank state. Compared with image generation, controllable video is more complicated, because besides the spatial controllability of video content, it also needs to meet the controllability of time dimension. Based on this, the research teams of Alibaba and Ant Group took the lead in making an attempt and put forward VideoComposer, which realizes the controllability of video in both time and space through combined generation paradigm.

In this study, the performance of VideoComposer is directly tested on nine different classic tasks, and satisfactory results are obtained, which proves the universality of VideoComposer.

Recommendation: Video generation with controllable time and space has come into reality, and the new work VideoComposer of Ali’s big model is on fire.

Paper 7: simple and controllable music generation

Authors: Jade Copet et al.

Paper link: https://arxiv.org/pdf/2306.05284.pdf

Abstract: At the beginning of the year, Google launched MusicLM, a big model of music generation, and the effect was very good. Some people say that this is more important than the ChatGPT of the fire, which almost solves the problem of music generation. Recently, Meta also launched its own text music generation model, MusicGen, which is free for non-commercial use.

Enter the first two sentences in the lyrics of Jay Chou’s "Qi Li Xiang" as follows: "The sparrow outside the window talks on the telephone pole, and you say this sentence is very summer-like" (in Chinese).

Recommendation: Meta open source text generates a big music model, and we tried it with the lyrics of Qilixiang.

I won’t die until I see my own engine.

  Never give up ambition


  Yang Zibin became a designer by diligent self-study as a workshop worker, so he was highly appreciated by Wu, and they also established a profound friendship. With the deepening of understanding, Yang Zibin admired Wu Daguan more and more. "Wu Lao only focused on one thing in his life, that is, designing and developing aero engines." Yang Zibin praised. Although, this way he walked twists and turns and how difficult-


  After graduating from the Aviation Department of Southwest Associated University in 1942, Wu Daguan got a job in Guizhou Dading Engine Factory opened by the Kuomintang, and was sent to the United States to study for three years. When he returned to China with great ambition to realize his dream of "saving the country by aviation", he hated the corruption and incompetence of the Kuomintang, and he resolutely chose to leave.


  The Communist Party of China (CPC), a young man who is interested in serving the motherland and an advanced political party representing the people, fell in love at first sight in Peiping before liberation in 1949. The latter ignited the hope in the former’s heart, and the former devoted himself to it.


  After the founding of New China, Wu Daguan organized and prepared the Aviation Industry Bureau as the director of the second production department. In 1956, he applied to be transferred from an institution to Shenyang Liming Aero-Engine Factory (hereinafter referred to as Liming Factory) and led the establishment of the first aero-engine design office in New China. In June 1958, the first jet trainer engine in China-Eruption 1A was successfully developed.


  At that time, China was poor, and everything needed to be done, so it was difficult to develop aero-engines. Wu Daguan led the scientific and technical personnel to cut through the thorns. At that time, the employees of Liming Factory often saw such a scene: Wu and his comrades were sitting on the grass and discussing issues enthusiastically. In August, 1961, the Engine Design Institute of Aviation Research Institute was established, with Wu Daguan as the deputy director, and the first engine test base in China’s aviation history was established …


  Wu Daguan said: "I will die unsatisfied if I can’t see the engine developed by our country." However, in the process of exploration and progress, he met unexpectedly during the ten-year Cultural Revolution. He was put in a bullpen, lost his freedom, and became blind in his left eye because of delayed treatment.


  However, Wu Daguan always believed: "The Cultural Revolution does not represent the party, and the line of the party’s’ science and technology power’ will not change." He sealed foreign technical magazines in red and kept on studying.


  At the end of 1977, shortly after the end of the Cultural Revolution, Wu Daguan was transferred to the position of deputy director of Xihang Airlines. "At the age of 62, he will be used at the age of 26." He led the scientific and technical personnel to master the advanced Spey engine technology in the world at that time and successfully developed the imitation. China’s aero-engine industry was about to turn a new page, but Wu Daguan was 66 years old at that time. In 1982, he was transferred to the Science and Technology Appointed Standing Committee of China Aviation Industry Corporation and retired to the second line.


  In Wu Daguan’s 40-year first-line aviation career, he organized and developed five aero engines, only one of which was assembled on the plane after being finalized, but it was not mass-produced; And these five engines are all made by imitating and improving foreign engines. This is far from his original ideal of independent research and development-some conditions are hard to change in an era, such as weak basic industries and shortage of professionals … But Wu Daguan never flinched and worked tirelessly.


  Today, China is one of the five countries in the world that can independently develop aero-engines, which is closely related to the persistence of Wu Daguan and many older generation scientists.


  Everything revolves around work.


  Liang Yan, Wu Daguan’s granddaughter, is a outspoken girl. In Liang Yan’s memory, the place where her grandfather played with her as a child was usually confined to his office. While Liang was playing, Wu buried himself in his work and sometimes looked up, instilling the concept of "aerodynamics" in her. Therefore, in the late autumn of 1982, my grandfather and her memory of flying kites in the rice fields outside the compound of the Science and Technology Commission was particularly precious and unforgettable.


  At that time, Liang Yan felt that she had been playing for a long time, but she was definitely not satisfied. Before going home, she asked her grandfather when she would take her out to fly a kite again. Wu replied, "When grandpa stops working." In the end, this became an empty talk-it was not until 22 years later that Wu Daguan, 88, officially retired. At this time, Liang is no longer a little girl who cares about flying kites, and Wu is too old to run any longer.


  In these 22 years, Wu Daguan worked almost every day. His daughter Wu Xiaoyun described her father’s simple life track every day: going to work at seven o’clock in the morning, returning to the office immediately after dinner, and not coming home until nine o’clock or ten o’clock. "He always feels that time is not enough, always works overtime, and works and studies in the office on Saturdays and Sundays."


  Wu Daguan has his own considerations. He wants to do his best for the development of aero-engines in China. Although he has retired to the second line, "many comrades in the front line of information may not have time to read it, so I’ll look at it and sort it out".


  "In the Science and Technology Commission, an advantage is that you can access a lot of information. After learning about the development of foreign engines, I feel more and more backward." Wu Daguan elaborated in his autobiography "My China Heart".


  In 1983, he asked the Ministry to compile the specifications of China aero-engines. At that time, this proposal was considered by the design and process department as "putting a condom on your neck". However, Wu Daguan believes that he will do whatever is conducive to the development of China’s aviation power. He personally served as the editor-in-chief of the editorial board, leading and organizing the translation of the general specification for engines published in the United States at that time-5007d. Based on this, it took four years to compile the General Specification for Turbojet and Turbofan Engines and the General Specification for Turboprop and Turboshaft Engines, which are suitable for China’s national conditions, and then they were approved as national military standards.


  "Now these two standards are still in use, which is the starting point for China’s aero-engine scientific research to move towards standardization. Later, engines such as Kunlun and Taihang, which made Chinese people proud, were developed on the basis of this specification. " Shi Yuanguang, former member of the Standing Committee of the Science and Technology Commission, commented.

Heavy! Hongqi Guoya is listed, and the top configuration challenges Mercedes-Benz Audi. Who will win?

This is not only a car, but also a redefinition of "luxury" and a symbol that China’s automobile industry once again shows its strength to the world. Today, we will discuss the story behind this new car and uncover its unknown secret.

From the moment it appeared, it was destined to be an ordinary car. The name of this car has a profound cultural connotation. The word "Guoya" conveys the high respect and inheritance of the national culture of the red flag, and also indicates that it will become a product representing the highest level of China automobile.

Hongqi Guoya is not only an ultra-luxury executive car, but also a declaration of "the return of the king". Hongqi brand has been a symbol of high-end cars in China since its birth, and this new car has pushed this status to a new height.

No matter from the body design, interior technology or dynamic performance, Hongqi Guoya is challenging the global luxury car market: we are not only known as the "national car", but also have the strength to compete with international first-line luxury brands.

This time, the red flag can be described as "full of heart" in design. Guoya provides 8 body colors and 3 kinds of two-color painting, which satisfies consumers’ ultimate pursuit of personalization.

Whether it is for business or private travel, every detail of Guoya shows luxury and dignity. You can choose the five-seat version or the four-seat version-even the most discerning customers can find their favorite choice in this car.

The craft and design of the interior make people feel like they are in an art palace. Every inch of leather and every detail have been carefully polished, showing the ultimate pursuit of quality by Hongqi.

Not only that, Hongqi Guoya is "stacking materials" to the extreme in configuration: intelligent four-wheel drive system, dual-cavity air suspension, rear wheel steering, and the world’s first flexible scroll screen, AR-HUD virtual reality head display and other cutting-edge technologies, which simply move the future automotive technology into real life.

Hongqi Guoya is not only gorgeous in appearance, but also powerful in core. The power system provides the choice of 3.0T and 4.0T hybrid electric power, and the maximum power reaches 290kW and 360kW respectively, which means that it not only has strong power output, but also gives consideration to economy and environmental protection. Compared with Mercedes-Benz S450L and Audi A8L of the same level, Hongqi Guoya’s performance is not inferior, even better in some aspects.

The meticulous carving of the red flag in the driving experience is even more exciting. Thanks to the advanced hybrid system, the vehicle starts quietly, but when it needs to explode, it can release strong power. This driving texture is not only the strong power output, but also the ultimate pursuit of driving comfort by Hongqi.

The listing of Hongqi Guoya is not only the launch of a new model, but also another sublimation of Hongqi brand strategy. The red flag is no longer just a symbol of "national car", but it is breaking the situation that "luxury cars are monopolized by foreign brands" with practical actions.

Guoya is clearly positioned as an ultra-luxury executive car this time, and plans to officially put into production in mid-2024, with an annual production capacity of 15,000 vehicles and a monthly sales volume of 1,200 vehicles. This figure is almost the same as the sales volume, which shows the market confidence of Hongqi in this car.

The appearance of Hongqi Guoya is undoubtedly a milestone victory for China automobile industry. It is not only a car, but also represents the confident rise of China automobile brands in the luxury car market. Through continuous innovation and breakthrough, Hongqi has changed from a simple symbol of "national car" to a global benchmark of China’s automobile industry.

Every time a new car is launched, Red Flag is proving to the world that China can not only build a good car, but also build a top luxury car. Hongqi Guoya is the best embodiment of this concept, which not only shows the technical strength and technological level of China’s own brands, but also conveys a sense of national pride.

As consumers, we can feel that Hongqi Guoya is not only providing us with a luxury car, but also standing tall for the China brand. No matter from the design, configuration, performance, or marketing strategy, this car reveals a high-end, atmospheric and upscale atmosphere. Through Guoya, Red Flag has proved to the world the power of China brand, and demonstrated our confidence and control over the future.

In the future, the arrival of Hongqi Guoya is bound to reshuffle the entire luxury car market. Perhaps, the next time you see the shiny logo on the highway, you will not only be amazed at its appearance, but also be proud of the "national strength" it represents.

Finally, what do you think when you see it here? Welcome to share your views on Hongqi Guoya in the comment area, and don’t forget to like, pay attention to and share, so that more people can feel this pride and strength!

Chopsticks Brothers’ new film, Funny and No Urine Point, opened the Film Channel Media Award.


    1905 movie network news
The latest masterpiece of Chopsticks Brothers (hereinafter referred to as "The Raptor Crossing the River") opened in the 2014 Film Channel Media Awards on June 16th. The film’s chief producer Ke Liming, Chopsticks Brothers Shawn and Wang Terry, and the heroine Qu Jingjing appeared to meet the audience. This is not only Shawn’s big-screen debut, but also the first time that "The Raptor Crossing the River" met the audience. In the process of watching the movie, the audience burst into laughter, laughing for 5 minutes and laughing for 3 minutes, and there was no urine spot in the whole film.

    This time, the Chopsticks Brothers broke through the scale in the film, not only making a big splash in Korean, but also having many martial arts action scenes, and also offering a large-scale passionate performance, fighting foreign girls in bed, which was amazing. At the audience meeting of the media awards that day, the Chopsticks Brothers also sang the film episode "Little Apple", which won the audience screaming again and again. It is reported that "The Raptors Crossing the River" will be released nationwide on July 10th.

    When it comes to directing a big-screen work for the first time, he was shortlisted for the film channel media award, and the founders expressed their great honor. Director Shawn said, "I am especially grateful to the Film Channel Media Awards for choosing this" Old Boy Raptors Crossing the River "as the opening film of the award." Qu Jingjing said frankly, "As a new actor, I am very eager to win the film channel media award, because it is a very professional award that also encourages newcomers." Ke Liming, the chief producer of "The Raptor Crossing the River", also expressed his gratitude for the media award, and admitted that the Chopsticks Brothers were sincere. "After the micro-film" old boys "was on fire, the Chopsticks Brothers were able to refuse the temptation, and it took them five years to make this film, and they did it themselves, directed and performed it themselves." The Raptor Crossing the River "is a sincere work."

Chopsticks brothers are decorated with two corners, hilarious and arrogant, showing Korean kung fu and spitting stones.

    "The Raptor Crossing the River" is the first big-screen work shot by Chopsticks Brothers after the popular micro-film old boys. This film continues the hilarious style of old boys, and this time it is upgraded in an all-round way, incorporating a variety of commercial elements such as hilarious, emotional, action, bed play and so on. It is reported that the film tells the story of brothers Xiao Dabao and Wang Xiaoshuai, who turned against each other because of their beauty. After many years, they went to the United States to pursue their musical dreams by coincidence, and they ended up in a mafia assassination.

    This time, the chopsticks brothers are divided into two corners. On the one hand, they are lonely diaosi who love music, and on the other hand, they have to play the "White Tiger Brothers", a Korean killer Ouba group with the same appearance. In the film, the two men were extremely hilarious, boasting more Korean and showing off their kung fu. Wang Terry even performed the magic of spitting stones, which made the audience laugh. Although the plot of the whole film is spoof, it is very Internet-oriented, but there is really no urine point.

    Speaking of these two roles, Shawn admits that his favorite is to play the Korean brother. "When I wrote the script, I thought this role was particularly interesting. For this reason, we also studied Korean and martial arts for a long time, especially the martial arts drama was very enjoyable and basically useless." Wang Terry revealed that he was actually a practitioner, and as a result, Shawn was bleeding. "I have a martial arts foundation. When I was a child, I liked to practice my own tricks, so I had an advantage. In the end, I beat Shawn with blood all over my legs. What a relief!" Shawn said gloomily, "We used a real wooden stick, and then Lao Wang (Wang Terry) hit me on the back with a stick, and once hit me on the head bone, which made me fall to the ground with pain. Originally, my facial expression should be as if nothing had happened, but I really couldn’t fit it, and my face was distorted."

Music diversity is still very bright. Little Apple and Raptors Crossing the River are expected to be popular again.

    This movie music is still a highlight of Chopsticks Brothers’ new film, and songs such as Little Apple, I Want to Go to new york and Raptors Crossing the River are expected to be popular again. However, unlike the micro-movie old boys, the songs in the movie Raptors Crossing the River are more diversified, not only with tearful nostalgia, but also with many styles such as nonsense and positive energy.

    In particular, the song "Little Apple", which has been exposed on the Internet before the film, is said to have become a must-have for aunt’s square dance. In this regard, Wang Terry said with a smile, "I wrote songs such as old boys and Father before, but I always made others cry. Even a fan cried when she saw me before. In fact, Shawn and I are usually very humorous, so in "The Raptors Crossing the River", we want to write a song that makes everyone forget their troubles and can sing and jump. " Chief producer Ke Liming also broke the news, "For the song" Little Apple ",Chopsticks Brothers and I specially found Uncle Bird’s choreographer team to choreograph the song. Now this song is also very popular in Korea, and we have received many invitations from Korean TV stations. It can be said that this time we successfully attacked South Korea!"

Wang Terry’s rich life is not shallow, and Shawn, a foreign girl, admits that she has no experience in erotic drama with Qu Jingjing.

    In "Crossing the River", the Chopsticks Brothers not only flaunted Korean, but also showed off English, among which the number of English lines was even equal to that of Chinese lines, which made people see the "internationalization" of the Chopsticks Brothers. The film also rushed out of China and entered the United States. More than 70% of the scenes were shot in new york. Chopsticks brothers this time is also a lot of happiness, Shawn and the beauty Qu Jingjing have kissed many times, and Wang Terry will fight foreign girls in bed, which is amazing.

    Speaking of the many passionate kisses and erotic scenes with the heroine Qu Jingjing, Shawn admits that she really has no experience. "Many people ask me, which is more difficult, playing drama or having sex? It must be a sex scene, because I have no idea where to make the effort! " In the face of Shawn’s remarks, Qu Jingjing laughed and said that he couldn’t take it anymore. "In short, we are both very involved in emotional drama!"

    Qu Jingjing, who graduated from Chinese opera, is the absolute heroine in the film. She plays a material woman in this film, which not only destroys the friendship between the chopsticks brothers, but also gives up the love between Bai Fumei and the male diaosi because of pursuing her dream. However, Qu Jingjing continued to defend the role that day. "In fact, the character I played is very real, which is the epitome of city girl. Now girls are under great pressure and are willing to work hard to pursue their dreams, so I can understand the decision of this role, but in real life, I won’t do it myself."
