Feb 28th, 2011. Downtown Sydney in sunset with rainbow
Rainbow over the Sydney Harbour Bridge
This is my first trip to Sydney, or the southern hemisphere.
And now, I'm totally fascinated by the city. There are lots of interesting architectures both old and new, and the atmosphere of the city created by combination of those buildings and the sea is just beautiful.
And I was very lucky that I got a magnificent view of the city in sunset, along with two rainbows.
This is a hand-maid miniature of a real city that took 10 people for 3 months to complete...
Okay, as some of you have noticed, that's not the truth.
The truth is, this is photo of a real city I took, spiced with a little visual magic by photoshop. This technique is recently known by the "diorama" photo filter on digital cameras like Olympus Pen. It's easy to make one, if you have a photo editing software. You just do 2 things - blur the top and bottom parts of the photo, and make the color vivid. It creates this effect of mimicking short focal length (it makes you feel like you're looking at a small object closely), and make it seems as if it's painted.
The way we perceive visual information is interesting. With the above setting, we automatically feel like it's a miniature. Not sure if our brain is guessing based on visual characteristics of blurriness or we are judging based on learned patterns of other (real) miniature photos. Anyhow, human has an amazing ability to see and imagine, and what we see is not always what actually it is.
I was thinking what's the best way to share my view or information about technologies while not commenting too much on specific events or companies in the industry. And I think I got a good idea. Talk about the latest Internet technologies or Computer Science in plain words and draw the vision for the future.
So, here's today's topic: Artificial Intelligence. It has been a popular topic of Sci-Fi movies, but it's becoming a reality. And what does it mean?
As some of you may know, IBM's computer "Watson" won the game Jeopardy. It must remind you about Deep Blue won against world chess champion Garry Kasparov in 1997. But actually, winning in chess is a simpler problem compared to understanding subtle human languages. The AI technology has got to the point where machines can understand what people say in natural language, and even answer a quiz.
At this point, some could ask "so computers started to think like human does?" or even "wow, then that means machines are replacing human?" Some could imagine those scenes of SkyNet terminating human being or some other Sci-Fi movies.
But actually the simple answer here is, no, they won't replace us. Computers are not mimicking how humans think. Because of such a difference, computers do some tasks really well and fast, but in other tasks have hard time doing something any person can do. Let me draw some examples here. On one hand, machine translation algorithm can translate this blog article to 10 or even more languages in a blink. If I'm asked to do this task, I'd freak out. On the other hand, it is very hard to make a machine correctly recognize different objects it sees, but even babies can do that.
So why is it? It's because computers "think" in a very different way than humans do. In modern AI algorithms, it (AI) stores lots of examples, like millions or billions, learn the patterns, and when it's asked about something, it compares the question with the pattern it knows. It's called Statistical AI. In the example above, learning patterns of the same sentences in different languages is something computers can already handle well, but learning almost infinite patterns of visuals of vast amount of objects is much harder problem, at least for now. Or even harder, if AI is asked "what do you think about this guy?", the only thing it can do is to return the statistics about what people thought about the guy.
So, in a nutshell, AI doesn't mimic human intelligence, but it enhances our capabilities by doing things that's almost impossible for humans.
I'm quite excited about the future of AI for the next decade. There are several major trends that will make AI more useful in everyday life. I guess most of you think AI is not relevant to you now. But I bet you - it surely will become relevant to your everyday life. Or I could say, you might be already using AI every day. I will talk about such trends in the next tech post.

When I took this photo, I was trying to capture as many stars as possible. And it turned out to look almost like stars on the blue sky. I exposed it for 30 seconds, and the camera showed me a different view of the world.
It's totally different from what I saw there with my eyes, but this other view is also beautiful.
I've had many different kinds of french toasts in my life, but this french toast at Hotel Okura in Tokyo was by far the best. It's crispy and light outside, and it's very creamy and soft inside. Once I had a bite, it melted in my mouth with pleasantly sweet vanilla flavor. Even though it has a very rich taste and flavor, it's very light and I felt like ordering more. (unfortunately, the one I ordered was the last one the restaurant had on that day)
Better yet, you can recreate it by your own using the recipe the hotel has publicized!
I changed the original plan to go to Lake Tahoe, and went to Napa Valley today with my wife and a friend. It's been 3 years since I visited there last time.
Of course nice vintages of wines are tasty, but aside from that, sceneries you can see in the area are also very pleasant. In this season, wine trees don't have leaves, so you can see the geometric pattern of vineyards. They have different beauty from the vineyards full of green in the summer. Also, yellow mustard flowers add nice color to the beautiful hill (I didn't take a photo of them while driving, though). Another thing I like is the architecture of Opus One winery. It's a very well-designed architecture both inside and outside.
And lastly, a yummy rib-eye stake with a glass of tasty wine at Ruthford Grill. Mmm, meat!
August 2010, Yakushima, Japan. Two huge ceder trees.
They are more than 2000 years old.
Roots of trees cover the ground.
This complex view itself is an art.
This tree is called "tarantula."
Thousands of years of their lives made them very unique.
Those are photos I took when I went to Yakushima in August 2010. The oldest tree in this island is said to be living for more than 7000 years. Those trees are quietly putting on years in deep mountains in this isolated island. It took me a full day to walk into the forest. But it was definitely worth the hike. The forest as old as our civilization has something totally different from an ordinary forest. Every view in the forest is a fresh surprise. It's the art made by nature in countless years.
Two towers in Tokyo and Paris. Tokyo Tower is modeled after Eiffel Tower, but they are strikingly different when we see them side by side. Tokyo Tower was made to function (even though it's beautiful as well), and Eiffel Tower was made to be an art.
Another view of Eiffel Tower
It's surprising how the complex combination of iron bars and lighting create the warm and even organic visual.
