This article is divided into two sections, the first section deals with the pictorial explanation of Principal Component Analysis (PCA) and the second section deals with mathematical explanation of PCA.
Classification Algorithms ส่วนใหญ่จะให้ผลลัพธ์ที่น่าพอใจก็ต่อเมื่อจำนวนของกลุ่มตัวอย่าง (Dataset) ของแต่ละกลุ่มมีจำนวนพอๆ กัน หากชุดข้อมูลมีความเบ้สูงคือจำนวนชุดข้อมูลแต่ละชุดมีปริมาณที่แตกต่างกันมากหรืออาจเรียกว่าไม่สมดุล (Imbalanced)…
I originally wrote this post in April 2016 but given the WSJ discussion on “World’s Largest Hedge Fund Is Building an Algorithmic Model From its Employees’ Brains” then I thought it was worth repeating but with the snark…

When machines use predictions to make decisions that can impact the rest of our lives, we are entitled to explanations of how they work and how predictive models were created (including the data that was used).
In his recent TED talk, Sam Harris discusses the looming rise of superintelligent machines, and our lackluster…
Presto i computer verranno addestrati e non più programmati. Cosa c’è di vero?
Some time around Halloween, I noticed that my ad-serving AI had gone from obvious “women-oriented”…
What is Artificial Intelligence?
We begin with a 2x2 grid of squares. Imagine that the squares in the grid are “pixels” in a binary image. We start with 4 pixels, forming a 2x2 grid.

An ongoing laundry list of news indicating we will make the robot uprising happen.
This article summarizes some thoughts on another fantastic UX Crunch Meetup around data and user experience with the title “When Do Humans And Computers Become A Single Operating System”. A series of talks by Alexander…
When working with a hypothesis with multiple features, the features might have values that can have vast differences in values. For examples, there are two features of house size and number of bedrooms. The former feature might have values that range in…
Yes, it’s the end of another year on this beautiful blue planet. I thought I’d celebrate by putting together a list of what I think were the most provocative articles from the incredible editorial staff at MIT Technology Review.
Everyone has an arch nemesis in high school. Mine was the most brutal one of them all, a dominating persona who went by the name “Mathematics”. It was fairly obvious why Math and I had a mutual dislike for each other: I gave it wrong answers and it gave…
Today: some theory and a GIF.
Stacey,
I agree that this is the direction we’re headed, I think you’re just looking father down the road than the technology has progressed yet not as far as it will ultimately go. I would say that the natural language processing we have today is like when spell check was not even a squiggly line but an entirely separate…
Nice read and definitely some really nice innovative thoughts, for the otherwise old-fashioned real estate industry! We’re trying to solve a problem for the rental market with ML, to match the right apartment to the right tenant. So theoretically you wouldn’t need any sales at all anymore.

This is a wonderful example how OpenAI could lead to unforeseen and counterproductive outcomes, and how people could get more positive outcomes pretty quickly, overcoming their natural preset beliefs. The problem is that a lot of people will deliberately ignore that outcome in the name of speed and…
I tell you, right now, OpenAI is going to do wonderful, unbelievable things sooner than anyone imagined, and it’s going to lead to artificial general intelligence (AGI) is a few years — better than human beings. Not a generation or two, but in 10–15 years, at most. Let’s see if I’m…
