There are many ways to study for a doctoral degree at Huacheng University. Excellent undergraduates can directly apply for a 5-year direct doctoral degree; first-year postgraduate students can apply for a 23-year master's and doctoral degree model, that is, two years for a master's degree and three years for a doctoral degree.
If others want to apply for a doctoral degree, they must rely on their master's degree certificate, contact their intended supervisor, participate in the application assessment twice a year, and pass the written examination and interview.
We are now in the summer vacation after the first year of postgraduate studies. After this summer vacation, I will have no chance to apply in the future.
Ling Zhi has been struggling with whether he should apply. In the past, he thought that a person like himself who was not good at words could only be a rigid teacher and that other jobs were not suitable for him, so he was still somewhat interested in continuing to conduct research. After all, in
In today's fiercely competitive world, only those with a doctorate can have the opportunity to apply to become teachers in major universities.
However, one year has passed since his graduate career, and there has been no progress in his research. He has been stuck in the whirlpool of data, so he gradually fell into confusion, not knowing what to choose for his future.
Some time ago, the light in the eyes of the short-haired girl made his confused heart suddenly become enlightened, as if the clouds were cleared to see the sun. In addition, the experiment gradually showed some improvement, so he made up his mind.
So what if it’s not suitable? So what if the experiment never progresses? Have you forgotten your original intention of being down-to-earth?
Look at the short-haired girl in front of you. She is not even sure what kind of thorns she will encounter in the future, but she still resolutely chose a major that she is unfamiliar with.
What about me? It has been 5 years since I majored in computer science. Did I start to doubt myself just because of a setback in an experiment?
Besides, whether you are suitable to study for a Ph.D. is not something you can decide by just thinking about it, nor is it decided by Director Wang. It is proven by your actual actions. Even if you are unable to publish a paper successfully in the future, within the time limit,
After graduation, just postpone your graduation and continue working. What are you afraid of?
After understanding this, Ling Zhi no longer hesitated. He decided to embark on this path, just work hard and leave the rest to fate.
Director Wang stopped typing on the keyboard, looked up at Ling Zhi with a smile, and said:
"Oh, yes, you can apply for master's and doctoral studies recently, right? Why do you suddenly have this idea?"
Ling Zhi had already prepared the manuscript and reported on the progress of his recent experiments. He also said that his family always supported him to continue reading, and he was mentally prepared.
"Well, it's good. In fact, I had a similar mentality to you back then. When I was studying for a Ph.D. abroad, it was only after some progress in the experiment that I gained more confidence and could be more calm when submitting manuscripts.
Facing the reviewers..."
Lao Wang talked about his experience studying abroad, and Ling Zhi was also very curious.
When Lao Wang was studying for his Ph.D., it was much more difficult than it is now. At that time, when he went to attend conferences abroad and got a hard copy of the conference proceedings, he was so precious.
Nowadays, the proceedings of any conference can be freely downloaded online after the paper is officially published.
Therefore, although Lao Wang did not catch up with the good times, he definitely made unparalleled efforts to reach where he is today.
"So although the decision to study for a Ph.D. is not necessarily a good one, nowadays, the choices after graduation are not as narrow as before. Do you think any of the major corporate algorithm laboratories are not recruiting Ph.D.s? The vice presidents of Penguin and Kexun
,How many people have graduated with a Ph.D.?”
"This is no longer the past, when you can do well by just typing a few lines of code. Nowadays, major companies have a high demand for algorithms. If you go to a university, postdocs or assistant professors are also ideal.
The choices are all suitable for you to continue to engage in scientific research..."
Lao Wang started his speech again, but Ling Zhi didn't feel bored at all. These things are valuable experiences, even if he doesn't use them now, and four years later, he will face a choice again. At that time, what he said today
Words will appear precious.
Ling Zhi discussed with Lao Wang for a while, including asking Lao Wang to learn about the daily life of a postdoctoral fellow, and then was about to leave. At this moment, there was a knock on the door outside.
"Please come in."
Four students came in outside the door, 3 boys and 1 girl.
"Uh, hello, teacher, I won't disturb you."
"It's okay, we've finished chatting. You are freshmen, right?"
"Yes, my name is Li Chang. Didn't we discuss this with you in advance? We will come over and have a chat with you today."
The boy in the lead greeted Lao Wang on behalf of everyone.
"Okay, you guys find a place to sit around. Lingzhi, you go back first. I will prepare the materials for applying for a master's degree and a Ph.D. program recently."
"Okay, teacher."
Ling Zhi took a step back and returned to the laboratory to do his own thing.
After a while, Lao Wang led the freshmen out of the office and greeted everyone in the laboratory.
"These are the students who are preparing to enroll in our laboratory next semester. You can chat with the brothers and sisters here to get a general idea of what they are doing and think about what research direction you will pursue in the future. There are still a few empty seats over there.
, you choose for yourself, sit wherever you want."
"I have finally become a senior brother and senior sister! Alas, there are no results, nothing worth showing off."
Ling Zhi smiled bitterly in his heart, but he had already calmed down. After preparing the materials, he asked Lao Wang to sign them, and then continued to adjust his model.
After a while, he felt someone sitting next to him and said softly:
"Senior brother, can I disturb you for a moment?"
Ling Zhi turned his head, and sitting next to him was the newcomer girl who had just appeared. She had double ponytails, long eyelashes, an oval face carved as delicately as a mold, a delicate nose, and a small cherry mouth. Her hands were clasped together with ten fingers.
On the thigh, wearing a floral dress, looking at Ling Zhi with a smile.
The girl in front of him was undoubtedly a sweet beauty. No matter who she was outside, she would take a second look. But it was obviously impossible for Ling Zhi to have any thoughts about his junior sister. He also smiled politely and said:
"It's okay, don't bother me. My name is Ling Zhi. I have just entered graduate school for one year. I don't know much. I will ask for your advice in the future."
The girl's smile always hung on her face and she said:
"Hello, senior brother. My name is Han Qingyue, which means lightness and joy. I have just been admitted to graduate school, so I want to ask my senior brother for your advice."
"Haha, each other. By the way, did the teacher assign you any research direction? Or are you interested in research?"
"Not yet. The teacher gave me a Chinese book on sentiment analysis, and I plan to study it first."
Lexus understands sentiment analysis.
Sentiment analysis in the early years basically divided texts into three categories: positive, negative and neutral.
As early as more than ten years ago, there were countless related papers. Everyone rushed to publish them at major conferences and claimed that they had achieved the best results on public data sets, although the classification accuracy may only be a few tenths.
percentage point increase.
Nowadays, the accuracy rate of sentiment analysis for this task has been improved to over 97%, and no one is wasting time on this task anymore.
Nowadays, the emotional analysis done by everyone will be more granular. For example, the emotion of a sentence is divided into multiple categories such as joy, anger, sadness, fear, etc., and see which category has the highest score, then which sentence is more preferred?
Class emotions.
The accuracy rate of multi-classification tasks is generally relatively low, and may have exceeded 50% in the past. Nowadays, some people have achieved more than 80% of this task, so more and more people have begun to further refine the task.
For example, we started to analyze whether the emotion in a sentence is joy, or pretending to be happy, or fear, or pretending to be afraid. This has brought about a series of related research tasks, such as emotional word extraction, emotional cause matching pair extraction, etc.
Although Lingzhi does not engage in this research direction, I did read such books when I entered school.
If you want to do sentiment analysis, it is indeed easier to get started, but it is not easy to achieve good results.
Everyone knows how to run models, but if you want to make new ideas and achieve better results than anyone else, the effort you may put in may not necessarily be less than your own. "Oh, it's good. This direction is easy to get started. If you have any questions, we can also
Communication, I have also learned some knowledge about sentiment analysis before."
"Okay, thank you, senior brother. So what research direction is senior brother doing?"
"Oh, me, what I do is a user identity recognition algorithm, which is to determine whether two accounts belong to the same person based on the user's text writing style..."
Ling Zhi briefly introduced his research direction, but did not elaborate on the difficulties he encountered. He simply said that he had not made any important progress.
"Anyway, we are still adjusting the model, so that's about it."
Han Qingyue listened carefully during the whole process without making a sound, not even a "hmm" sound of approval.
"Well, senior brother has done a great job. It should be difficult to obtain a real data set for this topic. It is said that the current troll account recognition rate is only 0.19%, which is far lower than expected, let alone account association.
."
Ling Zhi felt a little strange, but he suppressed his doubts first and thanked:
"Well, thank you for saying that. Although we can't get the real data set, we can still simulate a data set. The current experimental status has gradually improved, and it will definitely be better if we keep doing it."
Ling Zhi hesitated for a moment and added:
"However, where did you get the information about the navy account recognition rate you just mentioned? I don't even know such an accurate number."
The smile on Han Qingyue's face disappeared for a moment, but then returned to its original appearance and said:
"Oh, that, I also forgot about it. I don't know where I read the information from somewhere on the Internet. Senior brother, don't worry about it."
"That's it. But no matter what, you have helped me gain another knowledge point. Thank you."
"It's okay, but I want to thank senior brother."
"Well, is there anything else you want to ask?"
"Well... not for now. Senior brother, we will talk to you when we have the opportunity."
"good."
Han Qingyue stood up and slowly walked towards the seats of others, not even missing the three male freshmen. But no matter who it was, a few words in her few words would float to Ling Zhi's ears:
"Hello... lightness, joy, joy..."
What a rare girl who has such a strong thirst for knowledge and is so polite. Ling Zhi thought.
The three freshmen boys were also communicating with their senior brothers and sisters nearby, but not everyone was chatting with them. This suddenly made Han Qingyue stand out.
And because of her humility and politeness, she soon won the favor of many people. Ling Zhi heard from a distance that Senior Brother Zhou Min started joking with Han Qingyue:
"Hey, junior sister, if you can't do emotional analysis anymore, you can come to us. We have been working with Lao Wang for many years, and we have a lot of experience. We will protect you when the time comes, haha."
Han Qingyue still smiled and said without being humble or arrogant:
"Thank you, senior brother, I will consider it."
Ling Zhi smiled helplessly and shook his head. He remembered how embarrassed he was when he first arrived in the laboratory last year: he could only stay in his seat and even tiptoed to pour a glass of water, let alone take the initiative to understand.
He was afraid of exposing his ignorance in the direction that other senior brothers and sisters were taking. So Han Qingyue's actions in front of him made him very envious.
"Hey, Qingyue, how about having dinner with us at noon?"
Senior sister Zhang Xiaoxin has already begun to recognize her as a sister. However, for a long time, the laboratory has been in a state of yang and yang. Finally, a girl came, so of course she must be brought over to stand on the united front.
"Oh, senior sister, I'm sorry, I have other things to do, so I won't go with you."
"That's it, it's okay, just go about your business."
Zhang Xiaoxin seemed a little regretful, but still expressed understanding.
After a while, Han Qingyue was pulled into the laboratory WeChat group. Soon, Lingzhi received Han Qingyue's WeChat friend verification message:
"Hello, senior brother, I am Han Qingyue. Please give me your advice in the future."
