Why Natural Language Processing(NLP)?

Before getting into the topic, why is it important to have an NLP project in your portfolio? How can it help in your career?

The amount of text data getting generated is growing faster than ever. As per IDC, about 80% of global data will be unstructured by 2025. And this will be the pattern across the industries like retail, technology, healthcare, and anything you name it.

In the past, Organizations have been relying on structured data for extracting insights and the potential of unstructured data was unexploited. But now organizations have started to realize the value of unstructured data…


Elon Musk’s way of problem-solving

About 2000 years ago, Aristotle defined “First Principles” as “the first basis from which a thing is known”. This concept is still very much relevant and can help you to come up with an innovative solution for complex data science problems. The idea behind first principle thinking is to break down a complex problem into its fundamental parts and then use a bottom-up approach to build a unique solution that was not previously conceptualized.

In this article, I am going to explain to you how first principle thinking can be applied to solve data science problems. To make things simple…

I’m actively involved in mentoring and coaching people in data science. I also guide students to prepare them for a career in data science. Based on my interaction with them, I find many of them ignore the dataset while choosing a project. There are still many using dummy datasets for their data science portfolio projects. The goal of a portfolio project is better learning and to help with a data science job. The use of dummy data for your portfolio project doesn't help either with the learning or with getting a job.

Using a real-world dataset for your project offers…

When I started my career in data science a decade back, I just had a little bit of knowledge about the R, SQL, Gephi — an open-source tool for network analysis and basics about two or three algorithms, that’s it! But back then it was enough for me to get a data science job at one of the fastest-growing start-ups. Fast forward to the present, the scenario is totally different today. The industry is very competitive and very demanding as well. …
