The word “fuzzy” means something that is indistinct or vague, something that cannot be explained precisely. We all know what “search” means. That should give you a hint of what this blog post is about. Whenever you type something into the Google search engine, you will see that it always returns good results, even when you type the wrong spelling. How does it know what you meant? There are many different ways to misspell a word. How does it know exactly what word you have in mind? Continue reading “What Is Fuzzy Search?”
Quantum Computing And Machine Learning
Quantum Computing refers to the use of quantum mechanical phenomena to make computations. This field is making big strides in the last decade because it can actually help us solve some of the most challenging problems in the realm of computer science, particularly in machine learning and security. Machine learning is all about building better models of the world to make more accurate predictions and security is about safeguarding the things we have built. For example, if we want the machines to see things better, we need better models of how we process visual data. If we want to understand currency fluctuations, we need better models of how they change over time. If we want to create effective environmental policies, we need better models of what’s happening to our climate. So how can we use quantum computing to do these things?

How To Build A Web Crawler?
I was reading an article the other day and I came across the term “web crawler”. The context in which it was used got me a little curious about the design of a web crawler. A web crawler is a simple program that scans or “crawls” through web pages to create an index of the data it’s looking for. There are several uses for the program, perhaps the most popular being search engines using it to provide web surfers with relevant websites. Google has perfected the art of crawling over the years! A web crawler can pretty much be used by anyone who is trying to search for information on the Internet in an organized manner. It is referred to by different names like web spider, bot, indexer etc. Anyway, that article got me thinking about building a web crawler. I just wanted to fiddle with it and see how much time it will take to get something working on my machine. It turned out to be quite easy! Continue reading “How To Build A Web Crawler?”
Augmented Reality (AR) has been one of the most exciting fields to have come into prominence in the last few years. Back when people starting working aggressively on computer graphics, great innovations took place. Today, we have 3D movies with high end computer graphics, but it is still on the screen inside our machines. People then started to think how to pull the graphics out of the screen and integrate them into real world. The result of this effort was augmented reality. It tries to blur the line between what’s real and what’s virtual. It enhances our perception of reality. You can take a look at this video to see what I’m talking about. How does this technology work? How does it track the marker? Continue reading “Augmented Reality”
How Do We Recognize Objects?
Look around and you will see a lot of day to day objects. You recognize them almost instantaneously and involuntarily. You don’t have to wait for a few minutes after looking at a table to understand that it is in fact a table. Machines, on the other hand, find it very difficult to do this task. People have been working for decades to find a solution to this problem, but they have only been able to achieve an accuracy of around 65%. Why is it so hard for machines to recognize and categorize objects like humans? What’s so difficult here? We do it everyday and we get it right almost every single time. What’s the missing link? This is actually the holy grail of computer vision! Continue reading “How Do We Recognize Objects?”
Looking Into The Future With Google Glass
Unless you shut down all your gadgets and hid yourself in a dark alley with absolutely no connection to the rest of the world, you would have heard that the Google I/O conference started on June 27. It is one of the most exciting events in the realm of tech innovation. Google came up with a couple of new devices – A 7-inch Android Jelly Bean tablet called Nexus 7 and a social media streaming device called Nexus Q. But that’s not what this blog post is about. I want to talk about the insanely cool Google Glass demo that they presented in the conference. If you haven’t seen it yet, you can see it here. This reminded all of us why we love and adore Google. The technology falls in the category of Wearable Computing. When they started it out a few years ago, it sounded very futuristic, but not anymore. It’s here and we just saw it!
