🤓 Data mining คืออะไรในวิชาทางคอม
มาเดี่ยวเล่าให้ฟัง
วิชานี้แปลตรงตัวก็คือ "การทำเหมืองข้อมูล"
อุปมาก็คล้ายกับเราไปทำเหมืองแร่ที่ขุดมาจากใต้ดินแหละครับ
.
แต่เหมืองที่ว่าเป็นเหมืองของข้อมูลดิบที่มีขนาดใหญ่นั่นเอง
.
คราวนี้จะให้ลองนึกถึงเวลาใช้คำสั่ง SQL เราจะรู้อยู่แล้วว่า
ข้อมูลมันอยู่ตรงไหนใน (Table) ใช่มั๊ยละ
พอเราใช้คำสั่ง select * from .... where...
ก็เลือกข้อมูลมาได้ตามต้องการ
.
แต่ถ้าเป็นคลังของข้อมูลดิบบบบบบบบบ
ที่มีปริมาณมาก ๆ เช่น
ข้อมูลเว็บไซต์ในโลกอินเตอร์เนตที่มีเยอะมาก ๆ
ข้อมูลพวกนี้จะใช้ SQL ค้นหาไม่ได้หรอกครับ
ข้อมูลยังไม่แยกเป็นตารางเลย
.
แล้วอย่างนี้ข้อมูลที่เราต้องการอยากรู้
ได้แก่ "ความรู้" หรือ "Knowledge"
ซึ่งความรู้ที่ว่า ไม่ใช้ข้อมูลแบบที่คิวรี่โดย SQL นะ
แต่จะได้เป็นความรู้ในฐานข้อมูล (Knowledge Discovery in Database - KDD)
ซึ่งก็คือ รูปแบบ (pattern) และความสัมพันธ์ (associations) ที่แอบซ่อนอยู่ในชุดข้อมูลนั้นๆ
.
🤔 ซึ่งคำถาม แล้วเราจะหาเจอได้ยังไง?
ภายใต้ข้อมูลดิบที่มีเยอะเหลือเกิ๊น
แถมหายากอีกต่างหากละพี่น้อง?
.
ดังนั้นเราจึงหนีไม่พ้นต้องมาทำเหมืองข้อมูลกัน
ช่างไม่ต่างอะไรกับทำเหมืองแร่
กว่าเราจะเจอ ดีบุก ถ่านหิน เพชร พลอย ทอง ฯลฯ
โอ๋ต้องใช้เทคโนโลยี ขุดเจาะหากว่าจะเจอ
ไม่ใช่ของกล้วย ๆ เลยนะครับ
เพราะกว่าจะได้สิ่งมีค่าออกมา
ก็เจอแต่เศษหิน เศษกราด เยอะแยะเต็มไปได้
สิ่งที่ต้องการอยากได้มีน้อยนิดเหลือเกิน
.
Data mining ก็เช่นกัน
กว่าจะทำการขุดๆ และขุด
จนได้ความรู้ออกมา
มันทำไม่ได้ง่ายๆ ต้องใช้คอมทำ
ต้องมีอัลกอริทึมให้ทำงานอัตโนมัติ
ทำด้วยมือคนไม่ไหว ตายลูกเดียว
.
ด้วยเหตุนี้วิชา Data mining
จึงถือกำเนิดอุแว้ขึ้นมาในยุค 1970
ซึ่งมันเป็นศาสตร์ที่ต้องเอาหลาย ๆ วิชารวมกัน
หลัก ๆ ก็วิชา -> Machine Learning(สาขาหนึ่งของวิชา AI) + วิชาสถิติ + ฐานข้อมูล
.
สำหรับประโยชน์ของ Data mining
ทำให้การค้นหาความรู้จากข้อมูล
มันอิจฉริยะขึ้นครับ ไม่ต้องทำมือเอง
แต่ใช้คอมทำให้อัตโนมัติ ซึ่งจะมีประโยชน์มาก ๆ ตัวอย่าง เช่น
.
-ใช้จัดระดับความเสี่ยงของผู้ขอเครดิต เป็นระดับต่ำ กลาง และสูง
-ทำนายพฤติกรรมการซื้อสินค้า ว่าลูกค้าจะหยิบอะไรใส่รถเข็น
-หาความเสี่ยงของผู้ป่วยเป็นโรงมะเร็ง จากผู้ติดเชื้อไวรัสโคโรน่า
-หาเนื้อคู่เรา (อันนี้ล้อเล่นนะ ไม่รู้ว่ามีใครสนใจทำจริงเปล่า อิ ๆ ๆ)
และประโยชน์อื่น ๆ อีกเยอะมาก เป็นต้น
.
** หมายเหตุ
Data mining มันมีมานานแล้ว สมัยยังไม่ดังเท่าไร
ไม่เหมือน Data Science ซึ่งจะรู้จักมากกว่าในยุคนี้
เพราะเด็กม. 5 ก็จะได้เรียน Data Science กันแหละ
ในวิชาหลักสูตรใหม่แกะกล่องชื่อ "วิทยาการคำนวณ"
.
ถ้าเปรียบเทียบกับงาน
Data analysis กับ Data science
มันก็คือซับเซทหนึ่งนั่นเองตามรูปที่โพสต์
ซึ่งวิชาพวกนี้หนีไม่พ้นโยงใยไปในเรื่อง Machine Learning(สาขาหนึ่งของวิชา AI)

🤓 What is Data mining in computer subjects?
I'll tell you about it.
This subject translates right to ′′ data mining
The metaphor is similar to us to a mining that digs from underground.
.
But the mine is mine of raw data that is large.
.
This time I think about SQL order time. We will know that.
Where is the information in (Table)?
When we use select khả s̄ạ̀ng from.... where...
You can choose the information you want.
.
But if it's a treasury of raw data.
With lots of quantities like
There are a lot of websites in the internet world.
These information will be used by SQL.
Info is not separate yet.
.
And this is what we need to know.
′′ Knowledge ′′ or ′′ Knowledge ′′
Knowledge of not using Cory by SQL
Knowledge Discovery in Database - KDD)
Which is a pattern (pattern) and a relationship (associations) hidden in that data set.
.
🤔 which is the question, how can we find it?
Under raw data, there are plenty of them left.
Plus, it's hard to find, brothers?
.
So we can't escape. Let's do data mines.
What a difference to mining
Until we meet, coal tin, diamonds, gold, etc.
Oh, it takes a drilling technology to find it.
It's not a banana item.
Because it takes worth to get out of stock.
I have found a lot of rubble, rubble, and graphic. I can get full of it.
Wishlist is so little
.
Data mining as well.
Until I do the digging and digging.
I got the knowledge.
It can't be done easily. It takes a computer to do.
Algorithm needs to be automated
Handmade. I can't take it. I die.
.
For this reason, Data mining subject.
So it was born in the 1970 s.
It's a science that takes many subjects together.
Mainly subject -> Machine Learning (one branch of AI subject) + statistics wichā database
.
For the sake of Data mining
Make a knowledge search from information
It's a genius. Don't have to do it yourself.
But using a computer to automate which is very useful. Samples like.
.
- Take the risk of creditors low, middle and high level
- predict product buying behavior that customers will add something to cart
- Finding the risk of cancer patients from coronavirus infected people.
- Looking for my soulmate (I'm kidding. I don't know if anyone wants to do it for real. Haha.)
And many other benefits etc.
.
** Note **
Data mining. It has been a long time. When I wasn't famous.
Unlike Data Science which will know more in this era.
Because of the middle school boy. 5 I will be studying Data Science.
In a new course, unpacking the name ′′ Computational Science ′′
.
If compare to the work
Data analysis กับ Data science
It's a subtitle, one according to the photos posted.
The subjects are unavailable to machine learning (one branch of AI)

"When I step out the door with my Leica, I try to find frames that speak to me, frames that answer the question "why". I love architecture because of the sense of scale it provides both physically and spiritually. The metaphor created helps to rationalize the scale of what I feel in relation to the world. Knowing that you are small in this world can be scary, but can also be extremely motivating. I press the shutter to show a glimpse of what is in my mind, and I hope, others find parallels to what they are feeling and are filled with hope." -@firsthandaccount

Today, on World Suicide Prevention Day, we wear a black plaster on our wrist that says #howRu.
We want to call attention to this metaphor for suicide so that when people ask, we get the opportunity to talk about something that is often considered shameful and wrong.
Most plasters close wounds. This one, opens conversations.
A simple #howRu can make someone feel less alone, can take their mind off things, can give us the chance to listen to what they want to say.
#wearaplasterendthesilence
#samaritansofsingapore #howRu #everyday #listen

CAN YOU GET PERVERTED ANIME NOSEBLEEDS? (ANIME VS REALITY)
Nosebleeds from sexual arousal...
We’ve all seen those anime scenes where a guy catches a glimpse of a girl undressing, maybe she’s in a revealing outfit, or acting seductive to the guy. She could be flat out naked. And then suddenly blood shoots out of his nose!
A very iconic scene in Japanese anime and manga. Frequently used as a metaphor for sexual arousal. The nosebleeds can range from just a trickle, to full on fountain gushing. And in some cases, it even serves as a plot device, such as in Dragon Ball with Master Roshi.
Some say, it’s meant to be a powerful way to show the immediate change a person goes though when sexual arousal is induced. Others say it’s really more about the nervousness.
Then there’s the most obvious, an imagery for blood flow to the guy’s nether regions. And taking that one step further, the explosive, projectile nature of the nosebleed is said to be like an ejaculation!
There’s also the idea that the reason for the nosebleed metaphor is because you can’t show a boner in anime. So they had to get creative. Also one doesn’t even need to be capable of a boner to have pervy nosebleeds as some female anime characters also demonstrate this bloody trait.
Ok so, is this real? Does this happen to people in real life?
Shocking as it may be, it doesn’t seem to be backed by medical science. This probably only happens in the anime and manga world, although there are a few real life examples of this happening, but surely it’s just coincidence? Otherwise all late middle schools and high schools would be like a scene from Saw!
But how did pervy nose bleeds become a thing in Japan?
It’s actually existed for a while now. Manga artist Yasuji Tanioka is believed to be the first person to have introduced this nosebleed motif with his early 1970’s manga (Yasuji no Mettameta Gaki Dou Kouza). Subsequently, other Japanese artists liked the expression and began replicating it in their own works. And, we pretty much know where it went from there.
A bit of anime history to end things there.

10 THINGS YOU DIDN'T KNOW ABOUT THE HIROSHIMA ATOMIC BOMBING (& NAGASAKI)
*CORRECTION: In the video, the location of Nagasaki is off. It should be more on the left side of Kyushu island.
1) Godzilla
Godzilla, the giant Japanese dinosaur-looking monster, a worldwide pop culture icon; who’s been in numerous movies.
Why am I mentioning this? Well, Godzilla owes its existence to the atomic bombs. In the aftermath, with the devastation still fresh in the Japanese consciousness, Godzilla was created as a metaphor for nuclear weapons and their destructive capabilities.
2) The Korean Casualties
An enormous number of Koreans also perished in the blast. In fact, around 25% of casualties were Koreans. Korea was under Japanese rule at the time so there were many drafted or conscripted Koreans in Hiroshima & Nagasaki. It’s unfortunate that the Korean victims of this tragedy have often been neglected
3) Close Call Kyoto
Today’s Kyoto landscape would have been greatly altered, and not for the better, if the Americans had gone about their original plan. The targets were in fact supposed to be Hiroshima & Kyoto. However, the US Secretary of War at the time, Henry L Stimson, insisted on sparing the city
4) The Pamphlet Warnings
Just prior to dropping the Atomic bombs, the US Airforce released pamphlets or leaflets from their planes warning Japanese citizens of the impending destruction. They were largely ineffective.
5) The Little Boy & The Fat Man
These were the American codenames of the two atomic bombs.
6) The American Casualties
12 American airmen were captured, then taken to the Chugoku Military Police Headquarters in Hiroshima, where the American weapon of mass destruction indiscriminately took them out.
7) Go
An important Go tournament was held in the suburbs of Hiroshima, about 5 km from ground zero; a pivotal match up was ongoing between champion Hashimoto and the challenger Iwamoto. When the atomic bomb went off, people were injured, buildings were damaged, and the game came to an immediate halt. Fortunately no one died as tournament officials had earlier moved the game away from the blast radius after coming across the American pamphlets.
The players took this opportunity to have a quick lunch break. Afterwards on the same day, they finished the game. White won.
8) Operation Meetinghouse
As devastating as the atomic bombs were, it didn’t even rank as the most destructive bombing event of WW2. That title goes to the deathly firebombing of Tokyo by the US Air Force, also known as Operation Meetinghouse. This was estimated to be the single most destructive bombing attack not just in Japan, but in history.
9) The Flame Of Peace
The Hiroshima Peace Memorial Park was built in dedication to the legacy of Hiroshima as the first city in the world to suffer a nuclear attack. In the park, sits The Flame of Peace which has burned continuously since 1964, and will remain lit until all nuclear weapons are removed from the world and the planet is free from nuclear threat.
10) The Improbable Survivor
Tsutomu Yamaguchi worked for the Mitsubishi company, and on August 6th, 1945, he was away from home on a business trip in Hiroshima.
He witnessed the Little Boy dropping from the sky and the explosion ruptured his eardrums, blinded him, and left him with serious burns. But he was alive.
The very next day, he dragged his body to a station, made his way out of Hiroshima and back to his hometown. At home, he finally received treatment for his wounds.
Two days later, despite being seriously injured and heavily bandaged, he informed Mitsubishi that he was back from his Hiroshima business trip and ready to report to work. So, he went to work, as if nothing major had happened.
Yamaguchi was lucky to have survived the Hiroshima Atomic Bomb. However, he was unlucky that he went back home..
..to Nagasaki..
