Diving into Machine Learning!

Many believe robotics is on the cusp of becoming the next technological revolution and that we should expect a significant impact from “intelligent” robots in the near future. Even today, we can see robots and intelligent systems working here and there in different domains. But, robotics is only one application of machine learning and artificial intelligence (AI). Clearly, machine learning is serious business!  In this post, we review some machine learning techniques at a very abstract level. In a sense, the stone base of computer software is the...

A Brief History of Machine Learning

We saw earlier that although machines are stone-hearted, they can learn! As a subset of artificial intelligence (AI), machine learning algorithms enable computers to learn from data, and even improve themselves, without being explicitly programmed. That’s how your Siri communicates with you, or how your super car parks itself, or, partially, how your bank approves your loan request! Machines are getting more and more intelligent and AI is expanding to more businesses and industries. But does your fancy smart phone dream of digital sheep!? No, not yet…...

Text Mining to Understand more about Wine

  Just a hint of wild current with a smooth, buttery finish.  Whiffs of vanilla gently melded with soft, chewy tannins. Tastes good and it has a nice dark color. It goes well with fish… There are many, many ways to describe wine. The words change depending on your knowledge, expertise and where you come from. The French use different terms than Australians. Experts or people that work in the business have their own vocabulary and jargon that may not be well understood by the average consumer. And even though wine has been with us forever and has...
