Machine learning sounds like an idea from a science fiction movie. However, it’s not only real, but also the driving force behind some of the most recent technologies we use today. Why does this matter? Well, if you had this impression that machine learning is really hard and that it belongs only to people with a PhD in computer science or for masterminds that build artificial intelligence (AI) in some secret lab – you are wrong. In fact, you have been using machine learning applications every day and you didn’t even know about it!
Therefore, in this blog, we will take you through some of the most interesting machine learning applications that you might be new to. Whether it is aiding companies in making better judgments or further improving our conversation with gadgets, artificial intelligence is all over and that is something that has to be recognized by us today!
What Is Machine Learning?
Before we dive into the details, let us first give a brief description of what machine learning actually is. You may think of machine learning as a manner in which computers are able to learn from data without being given instructions on each step. In contrast to a human providing a device with an algorithm that tells it what to do next, machine learning algorithms give the device the capability to process data for itself, identify patterns, and conclude decisions upon what they find.
In short, you’re teaching a computer to fish, not giving it one. The wild part is that the computer keeps on getting better at fishing as time goes on, learning something from every catch.
There are two major types of machine learning:
- Supervised Learning: This is supervised learning whereby the machine is taught using a labeled dataset. It is akin to tutoring a child by providing him examples and then testing him if he has learnt it in the end.
- Unsupervised Learning: In unsupervised learning, the machine is given a whole bunch of data and told to do everything on its own. The machine has to try and find patterns or relationships in the data it was given to play with. It’s like being given a puzzle to solve but not being shown what the finished product is supposed to look like.
In recognition of these basic concepts, let us now explore some practical machine learning applications to demonstrate how machine learning is silently yet significantly propelling our lives towards a better, simpler and more captivating future.
