[PYTHON] Machine learning learned by a high school graduate system engineer at Coursera (laps 1-2)

High school graduate system engineer learns machine learning at Coursera (laps 1-2)

Last time: Machine learning learned by high school graduate system engineer in Coursera (0th lap)

First lap as an introduction

First of all, the machine learning course I took consists of ** videos, quizzes and hands-on coding **. And ** 1st lap ** has no practical coding, only ** videos and quizzes **.

Also, the content was focused on capturing a rough overview of machine learning, and I was able to proceed very smoothly.

`That's why I was alert, saying," I can afford it. " ``

Burning and 2nd week

It was sudden one day. In the main business, a defect was found in the released module. Such a report came in.

With this restoration work, I basically return home at 11:00 this week.

Of course, you can't work on weekdays. (Because I was studying English conversation for 50 minutes every day)

Fortunately, I didn't go to work on holidays, so let's proceed with the course on holidays. I thought so.

Saturday

I slept a lot on Saturday and went to the dentist in the morning, so I started studying in the evening.

Watch the video at once and answer the quiz. ** Only the remaining training tasks. ** ** Partly because I was hungry, I was satisfied with myself and the day ended. After studying English conversation, I became sleepy and took a bath.

Sunday

Maybe I was still tired, I had a lot of sleep on this day as well. Recalling my lack of exercise lately, I took a walk in the park. ``

I finish what I do on a regular basis, such as shopping and cleaning around the water. And tired, nap.

Before I knew it, in the evening. `Stretch lightly, have 25 minutes of English conversation, and have a pair of scissors and a light meal first. ``

If you were doing such an elegant thing, it would be dark outside.

Now, to practice.

However, ** The training content is quite heavy. ** **

Or rather, you need to learn a little about how to use something like the interpreter python code practice site used in Coursera.

And I don't use Python's numpy on a daily basis, so I need to know each method as well. (There is a lecture in the course)

Then, I misunderstood the upper right notation of T as the T power, and took time.

And so on, and finally, the dynamic determination of machine learning variables (gradient descent method) is slow on the web ... And the result is different from the expected value. (I was aiming for 100 even though I was clear with a correct answer rate of 70 or more. Maybe I'm tired)

** It's a small hour to reach midnight while playing around with various things and taking a bath. Finally clear! ** **

And I thought.

After all, the delivery date should be kept as fast as possible ... (I was able to finish the first lap early and advance the second lap)

Can you finish it safely? (Spoilers: The third lap is already over.)

** Continue next time! ** **
