In the last chapter we talked about understanding machine learning basics. Please follow me on medium for getting updated whenever I publish a chapter daily in my upcoming blogs. In this chapter, we will try to discuss the different types of Machine Learning.

There are basically 3 types of machine learning:

  • Supervised Learning
  • Unsupervised Learning
  • Reinforcement Learning

Supervised Learning

Supervised Learning is a Machine Learning task of learning a function, which maps input to an output based on collected input output pairs. In the previous chapter we discussed about the example of a person cracking a business deal and getting rewarded from…


There is one thing which we do throughout the day. We do it even when we are asleep at night. There is not a moment in our life when we are not doing it. And that is — “Thinking”.

Thoughts never stop!!!

Our thoughts can become fewer or excessive. But our thinking can not completely stop. When we are worried or if the mind is burdened or lets say, if someone said something and we are feeling bad about it, then the number of thoughts increases. At such times we overthink. It feels as if there is neither a comma…


Machine Learning is a process where we try to train a machine to predict things for us. There are many online materials where they have covered the topics of machine learning in great depths. But is these depth really necessary to have a career in machine learning. My answer would be NO!!! Indeed the concepts of machine learning is really necessary to understand the insights of the projects you will come accross in the future, but it makes no sense to build an ocean. …


It has been lockdown because of Covid for a year now. We humans have been sitting idle at home all this time. I am a person who has always been very keen on learning new skills. So, I started with learning ukulele and eventually learning digital painting now. I also love watching TV (most of the time, YouTube). So this lockdown, I have been watching a lot of pet videos.

Somewhere deep inside my heart, I always wanted to have a dog for myself.

“Life is not about expecting, hoping and wishing. It’s about doing, being and happening. It’s about the choices you just made and the ones you are about to make.”

Do you agree to this lines? Lets give it a thought, no expectations means no ambition, no hoping means we will not get anything and if there are no wishes there are no fulfillment. Some of us might think now that our whole life till date is based on these three words.

I expected to become “the designation you are today”, I hoped that I overcome every hurdles in my life…

Let me introduce myself. I am Nayanjyoti Das. I am from Assam (a state in India). By profession I am a Data Scientist. This is my first story on Medium.

After I finished my Masters in Technology, I joined an MNC in Noida. I have been staying here for 2 years. The city is quite busy compared to my native home. Here people don’t even know their neighbors. I have been exploring the plastic smile from people. Everyone tries to be so politically correct here. These are not complaints, but indeed my observations being from all together a different community…

  1. Start by watching videos in Youtube.

Here I am not saying to start learning then and there. Start by watching some of the videos in Youtube. Watch the experts playing the instrument…


Let us define “Data in general”. Data in general, can be defined as the facts that we have some existing information or knowledge that has been represented or coded in some form which is suitable for better usage or processing.

For understanding Data better, we have to understand two terms:

Variables: Variable is a characteristic of any entity that is capable of taking on different entities. like Y can take 2 or 3 or any other value. So, Y is a variable.

Measurements: It is when a standard process is used to assign numbers to particular attributes or characteristics of…

Bitlocker is an encryption feature which is included with the windows version starting from Vistas I suppose. It is designed to protect the data we have in our PC.

The corona Virus Pandemic is going on. Most of us are working from home these days. Its has been 100 days now, I haven’t been to the office premises. I was using my Laptop which was provided by my Office. It was a Dell Latitude 7490. I was on meeting with my colleagues most of the time.
