🧔เมื่อพูดถึงศาสตร์ AI หรือปัญญาประดิษฐ์
มันมีมานานแล้ว และก่อนที่มันจะนิยมในยุคนี้
ครั้งหนึ่งโลกเราเคยอยู่ในยุค AI Winter
หรือฤดูหนาวของ AI
หมายถึงช่วงเวลา ที่เกือบทุกภาคส่วน
ต่างหันหลังให้กับคำว่า AI
บริษัทต่างๆ ไม่ได้โฟกัส ไม่ไส่ใจลงทุน หรือวิจัยงานด้านนี้เท่าไร
.
💥 แต่เมื่อ Deep learning (การเรียนรู้เชิงลึก)
ซึ่งเป็นสาขาหนึ่งของ AI ได้ก้าวเท้าเข้ามา
ก็จุดประกายให้ศาสตร์นี้กลับมาบูมอีกครั้ง
อย่าง Machine learning ที่เป็นซุปเปอร์เซต
ของวิชา Deep learning ก็กลับมาบูมด้วยเช่นกัน
ทั้งๆ ที่เมื่อก่อนก็ใช้กันเยอะอะนะ
.
เมื่อพูดถึงเทคนิคหนึ่งของ Deep learning
ที่เป็นที่นิยม ก็มีหลายตัว
...แต่วันนี้จะพูดถึงเทคนิคที่ชื่อ
➡ Convolutional Neural Networks
ชื่อย่อคือ ConvNet
หรือบางทีก็เรียก CNN (ไม่ใช่สำนักข่าวชื่อดังของอเมริกานะ)
.
เทคนิคนี้นิยมใช้ในงานพวก Computer Vision
เอาไว้ทำให้คอมพิวเตอร์มีวิชั่นสายตามองเห็น 🤓
เหมือนสายตามนุษย์ก็ไม่ปาน ...เป็นไงเท่ห์เปล่า
(จริงๆ คอมมองเห็นรูปเป็นตัวเลขเท่านั้น แต่ใช้ AI ประมวลผลออกมาจึงเข้าใจ)
.
ตัวอย่างการประยุกต์ใช้เช่น
- Object detection เอาไว้ตรววจับวัตถุสิ่งของที่อยู่ในรูป แยกรูปสิ่งของจากภาพได้
- Face recognition เอาไว้รู้จำใบหน้า รู้อายุ เพศ สีหน้าอาการต่างๆ
- Image Classification เอาไว้แยกแยะรูปภาพ
เป็นต้น
.
✍ ผมเคยโน๊คเลคเชอร์วิชา
Convolutional Neural Networks เอาไว้
เผื่อมีใครกำลังเรียนอยู่
หรือสนใจเอาไว้ทบทวนได้ครับ

When it comes to AI science or artificial intelligence.
It has been for a long time and before it's popular in this era.
Once in the world, we were in the AI Winter era.
Or the winter of AI
Means a moment in almost every part.
All turned away from AI
Companies don't focus. I don't want to invest or research on this side.
.
💥 but when Deep learning (depth learning)
One branch of AI has stepped foot in
Well sparked this science back boom again
Like machine learning that is super set
Deep learning subjects come back to boom as well.
I used it a lot before.
.
When it comes to one technique of Deep learning.
There are many of them popular.
... but today will talk about a technique named.
➡ Convolutional Neural Networks
The initials are ConvNet
Or sometimes called CNN (not American famous news agency)
.
This technique is used in Computer Vision work.
To make a computer have vision, eyesight 🤓
It's like human eyes. It's not like... It's cool.
(Actually, the computer can only see the photo as a number, but I use AI to process it so I understand.)
.
Examples of application, e.g.
- Object detection. Let's catch the objects in the picture. Separate the items from the picture.
- Face recognition to know. Remember face, age, gender, facial expressions, various symptoms.
- Image Classification to digest photos
Etc.
.
✍ I used to note Lakecher subjects.
Convolutional Neural Networks
In case anyone is studying.
Or if you are interested, you can review.

## TRANSCRIPT E:
Alright this’s going to be a fun episode. It’s the first video that I speak English to my Vietnamese people - and heck, I’m not that ready to do this.
How can I talk to native English speakers with an accent. Will they judge?
By now you know that I’m not a native English speaker. I was born in Vietnam and only seriously learnt English in tenth grade or so. That’s why it’s naturally that I have an accent. It means that the way we talk is not as natural as native speakers do.
That’s why many of you DMed me and asked if people judge when you talk like this - or how I can talk confidently with an accent - I guess.
The answer is you - talk. Passionately. And don’t hold back.
But think about it. A lot of people say that they are not confident in speaking because they are afraid that people will judge them. They use it as an excuse to not learn English and speak in the first place.
Most people don’t even try. They keep thinking in their head that people will judge them. And they would never get better so they stop and they never learn.
So my friends, just talk. Talk passionately. Talk with all you have. There’s no how-to-talk tips or tricks. You just have to try. You just have to put yourself in the situation that you must talk. A lot. I guess that’s the secret. You must put yourself in situations that you must talk, a lot!
Let me give you a few examples.
Back in high school, I enrolled in this TOEFL class and every other day, the teacher would ask us to listen to tapes of conversations in English. I listened to them then write them down word, by word, by word. We literally use the cassette player because the teacher was kind of old-school cool that way. I had this big-ass SONY cassette player and every day I would tick … tick przz. Then in class, he would make round. Each of us will speak out loud, in front of the class each sentence.
But I knew that each session, I could only speak probably five or six times. That’s not enough. So I asked the teacher, if he could spent a few minutes each session to review a tape in which I pre-record all the conversations of that class.
That’s one way I did it. I put myself in the situation that I was held accountable by the teacher, that every session, I would submit my speaking cassette to him. And he was so kind to expect that and spend the time to help me. But here’s the thing, most people don’t ask. Most people don’t put in the work.
Another example,
All the years I was in college, each semester I would have a Math class with this specific professor that I like so much. But in the first period of my entire college life, he talked so fast with a lot of terminologies that I had no clues what they mean.
I was confused and overwhelmed so at the end of the period, I stayed and wanted to approach him to ask how I could do better. Would I be able to catch up with this class. And it took me seriously nearly five minutes just to go and talk to him because heck I was afraid that he would judge me, right?
But I forced myself to go talk to him and ask for his help. And he said I would be just fine. Go get this book and do some readings and he would help me as well.
The way he taught was so cool. He made each Math problem as an opportunity for students to present the solution in front the class. And guess what I did?
I knew that I would be shied. I knew that I was scared. I knew that I spoke terribly and I had an accent. I knew that I’m afraid that the whole class would judge because of my accent.
this. I’m still trying to get better. That’s why till this day, I record myself teaching something, speaking if not every day then every week.
You just have to talk. A lot. Every day.
