Chapter 338 Tan Xi Doesn’T Understand
Song He's voice came from the classroom and was amplified several times by the microphone. Tan Xi could hear it clearly even standing on the stairs.
"Students, turn to page 18! If you have a computer, turn on it. If you don't have a computer, prepare paper and pen. Let's practice!"
"There are four errors and six doubts in this set of data on the big screen. I give you three minutes to quickly calculate it! The minimum standard is to accurately find the errors. As for the doubts, crack as many as you can!"
"Those who have computers should give accurate values, and those who only have paper and pencil should list the steps clearly!"
Tan Xi hesitated and didn't dare to walk to the classroom door. If he couldn't see the screen, he couldn't see it. He could probably judge Song He's level by listening to what he said later.
Three minutes passed quickly, and Song He's voice sounded again.
"stop!"
"Raise your hands if you have finished? Very good! 10 students! Write your answers and names on the paper and hand it in now!"
"Let me talk about the conventional processing method for this set of data! First, merge the expression matrices and remove low-expression and low-change genes! In the second step, use linearridge to perform ridge regression analysis! Drug sensitivity needs to be modeled using the training set data!"
"The third step is cross-validation. Pretend not to know the drug response of a cell line, predict it through the data of all other cell lines, and do a correlation analysis between the predicted value and the real value!"
Tan Xi listened and snorted disdainfully.
But er, they are all commonplace basics!
"It's all routine up to this point. If you can't keep up, you're in danger!"
"Let's talk about some clever ways!"
"For the adjacency symmetric matrix A and the special matrix of the corresponding node, the graph neural network model is applied, the low-dimensional vector is represented as S, and spliced as the feature representation of the drug node pair, and finally a linear classifier is used..."
"After the linear regression model came out, we performed the first nesting and transformed it into this minimum surface model based on the weakening relationship of the nodes. The models of even-numbered edges and odd-numbered edges are completely different. Please watch my demonstration..."
"The nonlinear activation function is separated here. How to express the n-th layer of node i? I asked my classmates to ask...the boy in the middle of the first row! That's you!"
"Teacher, can you use an iterative method to simultaneously consider the enemy set and self-expression of neighboring nodes from n to i levels, and then use the total set to deduct it to get the friend set?"
"Very good! What's your name?"
"Lou Jinghui!"
"Okay, I'll remember you. Next, I'll find another classmate to write the aggregation formula on the whiteboard. Lou Jinghui's female deskmate! What's her name?"
"Xu Li!"
"Come up and write, class points will be deducted if you are wrong, extra points if you are right!" Song He's voice was decisive, "After aggregation, we can obtain two hidden layer representations of drug node i, and we can rebate to..."
Song He speaks very fast, but his enunciation is very clear, like a machine gun, firing continuously.
The atmosphere in the classroom was lively, and from time to time hundreds of people shouted "Yes!" "Yes!" "Got it!"
The sound shook the windows and the atmosphere was high!
On the stairs, Tan Xi's face gradually turned blue.
He heard a lot of mathematical terms but didn't understand the meaning.
When he was young, Tan Xi had some attainments in mathematics, but over the years he found it troublesome and always left the mathematics work to the students in the team. Over time, some basic mathematics knowledge had been completely forgotten!
Therefore, at this moment, he felt like he was listening to a book from heaven!
Tan Xi was shocked. He couldn't understand a lecture given by a newcomer! A classroom full of students can understand, but he can’t understand?
Standing on the stairs for a long time, Tan Xi faintly felt the aura of a powerful scholar. The lessons he heard at this moment must be valuable! It's just that he doesn't know how valuable it is!
After hesitating for a moment, Tan Xi opened the phone and searched in the address book.
[Ji Tianhe: Data Analysis Team Leader]
dial number!
The call was answered quickly.
"Teacher!" came a frightened voice.
"Xiao Ji, now bring the people from the data analysis team to the First Teaching 106 of Aerospace Town as quickly as possible to observe two classes!" Tan Xi whispered, "If you find it valuable after listening, you can come to listen at this time every day in the future. ! But absolutely don’t make any noise!”
"There will be a dinner party in the evening. During the dinner party, I will introduce you to three famous professors. The three professors are also attending classes in 106. You can communicate and exchange class content during the meal!"
"I understand, teacher! Let's go right away!" The voice on the phone agreed quickly.
Tan Xi hung up the phone, tilted his head and listened to the enthusiastic responses from the students, turned around and left with an ugly look on his face.
…
Finally, the morning's classes came to an end.
Song He stood on the podium, his mouth was dry.
The classroom effect is unexpectedly good, and the knowledge rebates are huge. In just two classes, Biology has been upgraded from Platinum Level 29 to Platinum Level 32, and Mathematics has been upgraded from Platinum Level 48 to Platinum Level 50, which is a rapid improvement!
My brain is overwhelmed and as hot as a furnace.
On the one hand, he has to maintain high-speed lectures and try his best to cram unlimited knowledge into the heads of all the students in the limited time.
On the one hand, after students understand it, they will continue to return knowledge. New knowledge rushes into their brains like a dam bursting, and they have to absorb it in time.
As Song He talked, he would give the whole class a minute or two to think, and took the opportunity to pick up the mask-type oxygen concentrator and take a few puffs.
Finally, the bell rang!
"Assign homework below!" Song He said, "The homework is very important and determines your course rating! If someone performs outstandingly, I will consider selecting him into my R&D team in advance!"
As soon as these words came out, hundreds of pairs of eyes in the classroom suddenly brightened up, staring at the teacher expectantly.
"I will send a copy of the data to everyone. The data is very confusing. Please analyze it according to the methods learned in class and then send it to me!"
"Every time you analyze data, you will get one extra class point! If you want to improve your points, you can actively ask for additional homework!"
"get out of class is over!"
Song He felt relieved, picked up his computer and textbooks and walked over.
…
laboratory.
Song He put the textbooks and computer on the table, as well as a bag of donkey meat to burn.
He quickly washed his hands, grabbed the donkey meat and burned it with one hand, and opened the computer with the other hand.
Previously, hackers from Teacher Xiang's team helped to collect a large amount of chaotic data. Song He quickly separated folders one by one, cut the chaotic data into small pieces, and sent them to the students in the class in a targeted manner. Everyone had a share.
Then, he took out a crumpled piece of paper from his pocket and quickly unfolded it.
[Monday auditor list]
The paper was full of handwritten names and player numbers, covering both front and back, and there were more than 400 people!
This piece of paper was passed around during class. Anyone who wanted to join Song He's research team had to leave their name on the paper. Song He would issue textbooks, homework, and final exam papers to them one after another. In addition to no points, no seats. , the treatment is actually the same as that of regular soldiers who have selected courses.
Song He spent a long time and sent out data folders to each of the 400 auditors.
What is a student?
Students are free labor, so if you don’t use it, it will go to waste!
Each student's data folder is about the same size. Song He estimates that after about an hour, high-level students will be able to hand in their homework one after another.
Just as he was about to start analyzing the data himself, an email suddenly popped up in the lower right corner of his computer.
Song He looked extremely shocked when he saw the title of the email.
