The difference between the first generation and the second generation
Take Canon's EF100 - 400mm lens as an example. There were the following differences between the first and second generation of the Grand White lens: 1. * * Zooming method **: The first generation uses a push-pull zooming method, while the second generation uses the mainstream rotating method. 2. Appearance: The black rubber on the front of the first generation White is in line with the principle of push-pull mechanics. This part is lacking in aesthetics, but the appearance of the second generation has been improved. 3. * * Picture quality **: The picture quality of the second-generation headset is better than that of the first-generation headset. 4. * * Price **: The price of the second generation is significantly higher than that of the first generation.

The difference between discriminative AI and generation
The main differences between discriminative AI and generative AI were as follows: 1. ** Cognitive simulation method ** - The discriminative AI used deductive rule input to achieve cognitive simulation. - Generative AI, on the other hand, was based on relativity and probability. It could achieve cognitive simulation by predicting the probability distribution between different elements. 2. ** Model Construction and Principles ** - The discriminative model is to model the condition distribution and directly learn the decision function Y = f(X) or the condition probability P(Y| X). It looks for the optimal splitting surface between different classes, reflecting the differences between different types of data and not the characteristics of the training data itself. The discriminative model often had higher learning accuracy in the face of prediction. For example, in the classification problem, it directly learned a conditioned probability distribution, which could be directly used to determine the class of the feature. - Generative models were used to model the joint distribution. Generally, a model would be built for each class. The joint probability P(x,y) would be calculated first, and then the Bayes formula would be used to calculate the conditioned probability. It contained more information and could be used to generate samples. It was more universal. The probability distribution could be used for other purposes besides classification, but it needed to be combined with the Bayes formula before it could be applied to tasks such as classification. For example, in classification, how many models were built according to the number of categories, and the joint probability of the new sample and each category was calculated respectively, and then the sample classification was determined.

The difference between generation verification and family verification
One generation verification and pedigree verification were two different methods of genetic testing. One-generation verification referred to testing only the proband through the second-generation sequence, and then performing a one-generation verification on suspected mutations. Pedigree verification referred to the simultaneous second-generation sequence of the proband and his parents. Each mutation of the proband was compared in parallel by three people to determine whether it was consistent with co-separation. The first generation verification was mainly used to improve the accuracy of the test, while the pedigree verification could confirm whether the genetic information carried by the embryo was consistent with the known hereditary diseases in the family to prevent the disease genes from being passed on to the next generation.

The generation after 60 is the worst generation
This statement was completely wrong. The post-60s generation was a generation with rich experience and made important contributions to society. Most of them had experienced the turbulent period, but after the college entrance examination was resumed, they actively accepted higher education and were able to seize the opportunity of the reform and opening up to develop themselves, making great achievements. They were the current successful generation and the mainstay of Chinese society. They had a strong sense of social responsibility, such as actively participating in activities such as "protecting the fishing island" and upholding the belief of "starting from now, starting from me" and "uniting to revitalize China". In terms of consumption, the post-60s generation had developed frugal and rational consumption habits due to their hard times. This was a positive attitude towards life. Moreover, after entering old age, although they might face some physical and psychological changes, they still had a rich inner world, a love for life, and a persistence and inheritance of traditional culture. In short, the post-60s generation had many qualities worthy of respect and affirmation, and could not be considered the worst generation.

The generation after 60 is a stupid generation
This statement was completely wrong. The post-60s generation had experienced many difficult times, such as coming from an era that was denied and experiencing criticism and reflection on that era. Most of them were the first generation to receive higher education after the restoration of the college entrance examination. They were able to seize the opportunity of reform and opening up to develop themselves and made great achievements. Although they were conservative and experienced, they were the mainstays of society. They had come from an era of lack of clothes and had developed a frugal and pragmatic quality. They were rational in their consumption and liked to set limits for themselves. When it came to smoking, many of them chose the affordable " Little Poor Cigarette " not because they lacked money, but because of various rational considerations. They had a strong sense of social responsibility and actively participated in social affairs, such as organizing activities such as "protecting the fishing island". Although they were once rebellious, they were a traditional generation. Through the re-acceptance and inheritance of culture, beliefs, and morality, they steadily became the backbone of society. Therefore, the post-60s generation was definitely not a stupid generation. The novel " Mother-in-law of the 60s and Daughter-in-law of the 80s " is equally exciting.

The generation after 2000 is not a lost generation
The post-2000s generation was not a lost generation. From the perspective of their growth experience, they faced many challenges in the process of growing up. For example, in terms of studies, they might be affected by SARS-infected in junior high school, experienced online classes in high school, faced reform in college entrance examination, closed school online classes due to the epidemic, and suffered from reduced consumption and poor employment environment when they graduated. However, they also showed their unique advantages and positive side. In terms of attitude, they had their own way of life. Although some elders thought that they were a little unique, such as messy rooms, but they were particular about going out, and they did not follow the traditional routine of work and rest, this was also a manifestation of their pursuit of personality and freedom. They were not bound by the traditional ways of the world and could deal with social relationships in life freely. In terms of consumption, they did not have the pressure of car loans and mortgage loans, so they could face life with a relatively relaxed attitude. In terms of career pursuit, despite the employment difficulties, they were also trying to find a way out. They took the public entrance examination or struggled in a low-paying and high-demand employment environment. They did not completely rely on their elders. Moreover, in their childhood, even if they did not have Wi-Fi, they could still get happiness from simple games, cartoons, and limited pocket money. This showed that they had strong adaptability and the ability to find happiness. In short, the post-2000s had their own characteristics and positive attitudes towards life. They should not be regarded as the defeated generation.
