AI designs its own video game

Interesting article about AI system Angelina that is capable of generating video games on its own using evolutionary algorithms.

If Tiny Flying Robots Don’t Kill You, Large Running Ones Will

Darpa, ~~creator~~ funding agency of robots both cute and scary, has now shown us that you can run, but you can’t hide. Meet the Cheetah, an ambulatory creation that has just set the record for robot landspeed at 18 mph. While it may look like it’s running backwards thanks to its morphology, rest assured that when it’s bearing down on you in a post-apocalyptic wasteland you won’t make the same mistake.

Considering that that fastest humans can sustain around 15 mph, maybe it’s time to start developing bullfighting skills?

In all seriousness, Darpa is pushing the envelope marvelously these days, and this creation is a true feat of genius in technology. They are frontrunners for “Best Government Research Arm of 2012” so far. And for now, at least Cheetah’s connected to those wires.

Live Translated Video Calling!

Looks like language barrier is breached. Vocre is launching live translation feature for their iOS video calling app. It works very much likes conversation mode in Google Translate that was launched last year but is designed for video calls rather than real life meetings.

Google Knowledge Graph Could Change Search Forever

Google now wants to transform words that appear on a page into entities that mean something and have related attributes. It’s what the human brain does naturally, but for computers, it’s known as Artificial Intelligence.

Although it sounds less fascinating than some kind of flying robot, this type of research can actually have a great influence on our productivity by improving the process of finding the information. Google is certainly not the first attempting to extract more knowledge from web pages than keywords but given the resources Google has, both material and intellectual, it is reasonable to expect practical results soon (1-3 years).

Q:Bro , thanks for your blog , half of your blog will be on my presentation next week. I was wondering if you know any good examples or any advances of AI on medical fields ?

There is a lot of AI in medicine, mainly used for diagnosis and medical image processing. For example, diagnosis of pancreatic cancer (the one that killed Steve Jobs) from computed tomography imaging.

Among recent demos of AI in medical field the one in this video is perhaps the most spectacular.

There are a lot of hopes for future application of Watson in medicine. Here is the video about it I posted before:

Good luck with your presentation.

Sentiment Analysis for Twitter

Want to know what people think about a particular issue, a product or a public person thеn sentiment analysis is the technology you might be interested in. The link above demonstrates how sentiment analysis is applied to Twitter feeds to mine the opinions about Obama.

The task of sentiment analysis is to determine the polarity of text, such as negative, positive or neutral. The basic way to do it is to look for words that express the corresponding attitude. Example of positive words are “good”, “satisfied”, “happy”; negatives are “fail”, “sad”, “broken” and so on. The trick is to collect a large vocabulary of such words automatically and to consider the context where they are used in.
