Over the last few decades, we have seen a lot of technologies come by and make a significant impact. Most of these technologies, if you have noticed, revolve around intelligent actions. Let’s say you are in the middle of a street and you want a cab. We can solve this problem in a couple of different ways depending on the level of intelligence we put into our solution. How can we design something that can make use of all the data and provide the best possible solution to the person in the middle of the street? We can say that intelligent action involves search in some way. Searching is needed in a variety of situations, so developing mathematically and computationally strong algorithms is an absolute must. In most of the real life situations, we don’t really know where to look or how a particular search is going to pan out. How do we formulate this?

What Is Fuzzy Matching?
This is a continuation of the previous blog post on fuzzy search. We use fuzzy matching algorithms in fuzzy search to come up with the search results. The strength of a fuzzy search algorithm heavily depends on the strength of the fuzzy matching algorithm that is being used. The concept of matching refers to an input being matched to a set of entries, or records, in your database to come up with the best possible match. We encounter this scenario very frequently in our everyday lives. Whenever you are looking up a word in the dictionary or when somebody is looking up your account during a customer service call, some form of matching is being used to get the answers. So how exactly does fuzzy matching work? What’s the big deal here? Continue reading “What Is Fuzzy Matching?”
What Is Fuzzy Search?
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?

Content Delivery Network – Part 2/2
In the previous post, we discussed about content delivery network (CDN) and why we need it. This post is a continuation of that topic. Here, we will discuss about the pros and cons of using CDN. CDN obviously helps the sites that experience heavy traffic. Most of the times, you will think that just using a CDN will deliver a better performance, but this is not always the case. If you don’t choose your provider carefully, your site will end up suffering. Let’s look at some of the advantages and disadvantages of using CDN. Continue reading “Content Delivery Network – Part 2/2”
Content Delivery Network – Part 1/2
Internet users today are demanding faster and higher-quality services from their media hosting companies. Being an internet user yourself, you should know that we place a high demand on these services. This is the reason quick access and delivery of rich-media like music, photos, videos etc has become a top priority. Wait a minute, why we need to care about all that? Doesn’t that just happen somewhere on the server? Well, who do you think makes that happen? It’s the people who manage the website. The beautiful site that loads all the high-resolution images for you doesn’t just work magically by itself. It needs to be optimized in a zillion ways for you to not feel the pain. All of your pages, including your photos and videos, will load quickly and instantly if the website owners use the right Content Delivery Network (CDN). Let’s see what this whole thing is about, shall we? Continue reading “Content Delivery Network – Part 1/2”
Investors Are Unimpressed By Facebook’s Graph Search
Facebook unveiled its graph search recently. This announcement was highly anticipated and Facebook is banking on it to generate some revenue. While it is very good from a technological point of view, the unveiling didn’t exactly impress the investors. The stock prices actually went down after the announcement. Facebook really wants to create a source to generate sustainable revenues. What exactly are the investors looking for? Even though graph search looks promising, why aren’t the investors convinced yet? Continue reading “Investors Are Unimpressed By Facebook’s Graph Search”
Robot Vs Turing
In one of my previous blog posts, we discussed about measuring computer’s intelligence and how we can use the Turing test for it. After Turing proposed that test, a lot of people realized its importance and started working on it. People really wanted to believe that machines are indeed capable of thinking. We need a way to determine if a computer is thinking on its own. The biggest obstacle here is that this is a very subjective topic. Given the knowledge that something is indeed a machine, how do we ascertain that the machine is capable of thinking? Continue reading “Robot Vs Turing”
The Genesis Of Genetic Algorithms
Let’s say you have a function and you want to optimize it. In real life, this function can take many forms like choosing the right set of features for your car while keep the price low, picking the best possible apartment considering all the different factors like location, rent, closeness to stores etc, making a business plan, and many other things. In fact, we continuously use optimization in our everyday life without even realizing it. The interesting thing to note is that we don’t get the most optimal answer every time. We just look around for a while and stop when we get a good enough answer. More often than not, these answers are sub-optimal, mostly depending on the initial point we chose. So how do we get to the best answer? There might be billions of options, do we need check all of them to get to this global optimum? Continue reading “The Genesis Of Genetic Algorithms”
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?”
