Lets me start by telling you that this is a very common practice in the industry that is using AWS cluster and zeppelin notebook. This is my personal experience that whenever you want to see your script you need to start EMR Cluster and then after that only you can able to view your script.

The data analyst will work on Data Engineering and Data visualization. While Business Analyst will work with Data…
Let’s start with this, as you know that almost 70 percent of the time you are dealing with data Engineering stuff. Data Engineering includes Data formation as per business demand ,data wrangling, Data Cleaning, and Data preprocessing.
Some of the common programming languages used across all industries are Python, R, Scala, Splunk, SQL. From these, you should know at least 2 languages. Again for newcomers, I would like to suggest them to start with python and SQL.
During my year of experience, I almost devoted my 80% of the time in Data preparation, Data Formation, and other operations…
Do you know 98% of people don’t know what they are learning in Data Science? Hey, I want to become Data Scientist, what should I do know? From where should I start? Which programming language should I learn, Is it important to learn cloud technology like AWS, Azure, etc.
I will try to answer them as per my experience. The first question when I asked people why do you want to become Data Scientist?
The common answer, because there is a chance of getting more money and growth. Seriously, are you sure .wait …

Perfect tools for cross-checking your results but how?
Let's talk about my journey with pycaret. I started using it from April onwards and it really helps me a lot during model building. Absolutely perfect for cross-checking your result if you are new to machine learning, when I started with the Machine learning project I always want to try a different type of model and always try to give my best to improve my model and it takes a lot of time because if you go through a normal procedure you have to run all machine learning algorithm one by one…
