Dialogue Wei Xiaoliang: The thoughts and stories behind the very wise correction

On the last day of May, assistant Wei Xiaoliang, president of New Oriental's future, announced his departure to join online education, leaving a suspense. "Dormant" two months later, he and partner Shaocheng with the entrepreneurial project "extremely intelligent Correction Network" return. The product, which he describes as "redefining the teaching of spoken and writing", does make a lot of people's eyes bright: Correcting this neglected demand can be so played. What are the secrets behind a nuanced report? What's the next step? Today, Wei Xiaoliang received an exclusive interview with the Internet, detailing the thoughts and stories behind the highly intelligent correction. "Writing and speaking this type of output skill is useless only in class": When does this idea start? Make an intelligent correcting platform. Wei Xiaoliang: Almost six months ago. When I was a graduate student, I majored in data mining, and my partner, Lao Zhai, had a very deep understanding of oral correction, and I was correcting the composition, which is now the case. Multi-Knowledge Network: In the traditional institutions of the classroom, correcting the role played? Wei Xiaoliang: There are no corrections (links) in the traditional classroom, or corrections but particularly inefficient. Usually students send a composition to the mailbox, the teacher use Word revision mode to change. It is possible to change the instrument, but if you want to teach by change, you must mark the wrong type. Revision mode is not telling you this, it only tells you what to change. Extremely intelligent correction is to use their own development of the modified control, there are more than 30, corresponding to different types of errors, such as the subject-predicate agreement, noun class errors, syntax errors, and eventually generate a correction report. Multi-Knowledge Network: Good understanding of composition correction, oral correction how to do? Wei Xiaoliang: Voice grading Technology, students submit a spoken language, our teacher with correcting space, in the student's voice, add his voice, statistics all errors at the same time, give a sound correction report. All you can hear is sound, and there are some textual comments. In this process we will play down the text, see can not improve the oral and listening. All the foreign teachers including Zhai teacher, is to take the pure beauty and English sound, to correct, this is called sparring. Small Longnu (more know net Note: Shanhaiyan) do 91 foreign teaching net I very disagree, that is just a bunch of foreigners pull over to accompany chat. There is no system for chatting. Chatting can only solve the problem of the courage of the students to speak, can not give him error correction. Do you think it's important to be confident? Of course important, but students can not really improve, dare to say does not mean well. In addition, we will be based on years of teaching experience and my set of neural network algorithm (multi-net note: "Maximum likelihood of bidirectional associative neural network" algorithm), to reverse all the test class of oral scoring standards. Multi-Knowledge Network: Some people put forward a point of view, education and training needs can be created and inspired, as early as the "can not lose at the starting line." Correcting is an interesting point, students do have this need, but may not realize, how to inspire or create this demand? Wei Xiaoliang: It takes a process for any good thing to be accepted, such as this (cell phone), people answerTouch screen takes time. When I talk about this concept to any parent or student, they all realize that, oh, composition and oral English can be changed. A lot of training institutions are crazy to play Masters card, meaningless. Objectively speaking, I and Old Zhai is a top teacher, but after we reflect, all feel that the past teaching is problematic: composition and oral output class skills, only class is useless. That explains why people spend tens of thousands of of dollars in classes without improving. Because no practice, no one to change. Then why do I and the old Zhai's student score is more ideal? In the absence of extremely intelligent correction, old Zhai is using micro-letter to the students, I used to be an article for students to change the composition. Can you imagine how many teachers would do that for free? A hands-on teaching is a teaching. Multi-Knowledge Network: Very much like private schools. Wei Xiaoliang: The essence of education is to return to private school, otherwise it can not be personalized. Data mining on the basis of pure artificial correction: You are the concept of intelligent correcting platform, but there are also artificial parts. Wei Xiaoliang: The intelligent embodiment of the set of data mining algorithms. According to the manual correction, then statistics its results, tell the students: you are prone to make mistakes. So as to achieve targeted learning. Many people think that smart correction is the machine correction, in fact, we are purely artificial correction. I have done a very important thing in the new Oriental nine years. The standardized teaching service system, which has been used so far. I think any east first standardization, and then training is very convenient, as long as the recruit excellent people to train him. This is like McDonald's can be bigger, Lanzhou beef noodles do not do the same. Multi-Knowledge Network: Predict students may make mistakes, the equivalent of you not only the back end has to correct the link, the data analysis after the front-end can also do prevention, prevention work specifically how to do? Wei Xiaoliang: By background statistics, to give students more personalized push, for example, we will put all the questions will locate the difficulty coefficient, according to the students in front of the score, pushed to fit his difficulty problem. The student has changed 5 compositions, made more than 20 kinds of mistakes, but the frequency of each kind of error is different. Finally I will tell him that these five kinds of errors represent your syntactic problems, and these six types of errors represent a problem with your noun clause, which is based on the knowledge point of data mining. Our data mining system is difficult to do is that only knowledge of data mining or education, must be two understand. I chose this major (graduate student), so many years finally broke out, let me very happy. When I was in New Oriental, I did a set of matching algorithms for studying abroad, which is the first application, we can calculate the matching rate between students and universities, very accurate. Multi-Knowledge Network: And now is the same. Wei Xiaoliang: It is recommended to fit his things, do a match. How to control the quality: a composition three times to correct the network: to one-on-one, or manual, the sense of the model is heavier, your official website also mentions that now has hundreds of foreign teachers. Wei Xiaoliang: It's not that heavy, we're all in the relationship with all the foreign teachers, they're distributed all over the world. We train them through the web or face-to-face. Multi-Knowledge Network: Foreign language real service has a commonThe problem is to manage foreign teachers. Your teaching staff is not small, how to do the management of foreign teachers? This relates directly to the quality of the correction. Wei Xiaoliang: We have a position called Super correction, which is full-time. All foreign teachers finished correcting, Super Correction Division second, and then the composition I review the third time, oral English old Zhai trial third time. Three audit before giving students, not outside the teaching reform into what kind of immediately post to the students, quality control we certainly have to do tight. More knowledge Net: That early stage your workload will be very big. Wei Xiaoliang: Very big. But the introduction of these days, praise 39, a piece of applause. Because (students) do not think so, of course, there are free reasons, to first let them experience. Multi-Knowledge Network: How many super correction teachers in the team? Wei Xiaoliang: About 10%, more than 10, basically TOEFL one, sat one, GRE one, different fields, so to divide. Super correction teachers are very understanding of this aspect of foreign teachers, including Stanford University, Berkeley, East Asian culture, and even the English language test of the Americans or the British, there are some IELTS examiners and retired TOEFL examiners. We split it up with them. Multi-Knowledge Network: Now a day to correct the amount of 300, such as the expansion of 10 times times, you are artificial correction, will not feel labored? Wei Xiaoliang: No, our foreign teacher reserves are very large and we do not use all the resources at all. Foreign teachers are now in a state of excitement, the more you change, the more income, according to the billing. Multi-Knowledge Network: Now or free trial, when to charge? Wei Xiaoliang: In fact, many students already recharge. Multi-Knowledge Network: Some online education companies interesting is that there is income on line, which is very different from other Internet products. Wei Xiaoliang: I guess a lot of people can't imagine that we've created a demand. More than 300 a day, there are also me and old Zhai personal reasons, students trust us. "Smartpigai the Future is to internationalization" multi-Knowledge Network: Next product or functional aspects of what planning? Wei Xiaoliang: The end of August will be on-line business documents, study abroad instruments, job-seeking documents and academic papers correction; Speaking, we will develop daily oral correction, such as you want to chat with beautiful women, introduce yourself in English, or make a speech to the public. Another October 10 we will be online another product smartstudy. Multi-Knowledge Network: The first day cumulative number of registered users more than 8,310, good results. What do you and Miss di expect for this project? Are there any measurable metrics? Wei Xiaoliang: We only look at one indicator: Repeat submission rate, frankly, repeat customers. After the second time to explain that he recognized our service. Also need to pay attention to, through our correction, the score in the end has not improved? This needs to be tracked, students will come to submit, and the students will be rewarded with more points. Multi-Knowledge Network: The desire or vision of this project? Wei Xiaoliang: The vision is to redefine spoken and written "teaching" and "learning". What we are doing now is that some Chinese teaching experts combine with foreigners to provide correction services to the Chinese people and future foreign markets. SmaRtpigai the future is to internationalization, foreign correction/language polishing service is very hot, we will certainly promote to the United Kingdom and the U.S., because our team is also foreigners and teaching experts. Multi-Knowledge Network: This model is really flat. October Smartstudy, is two team doing, or a team? Wei Xiaoliang: A big team. I am smartstudy product manager, Zhai Teacher is Smartpigai product Manager, I Misting study, Zhai teacher catch Pigai, but Pigai content system and product system is I build, study shooting is Zhai teacher. We are the true co-founder, mutual penetration, complementarity. When it comes to partners, how does entrepreneurship feel for months? Wei Xiaoliang: Very cool. I wrote a word in Weibo, "entrepreneurship is a one-way road, once on the eyeful are only industry opportunities, no longer career opportunities." Objectively speaking, my more than 1 million annual salary has given up a very comfortable day. But after starting a business, it is a qualitative change. Although I now personal income, the past one-tenth are not, but the harvest is more than 10 times times in the past. That's the fun of starting a business. Many people do not realize this material decline, but spiritual pleasure, he does not deserve to start a business. Often someone mention "I want to start a business", this is impetuous performance. He looked forward to the wealth he had done after his venture, but he could not imagine how much he would sacrifice. Work seven days a week, 88 hours a day, probably 7x18.
