Python Pro Tip: Start using Python defaultdict and Counter in place of dictionary

Learning a language is easy. Whenever I start with a new language, I focus on a few things in below order, and it is a breeze to get started with writing code in any language. Operators and Data Types: +,-,int,float,str Conditional statements: if,else,case,switch Loops: For, while Data structures: List, Array, Dict, Hashmaps Define Function However, learning to write a language and writing a language in an optimized way are two different things.
3 Awesome Visualization Techniques for every dataset

3 Awesome Visualization Techniques for every dataset

Visualizations are awesome. However, a good visualization is annoyingly hard to make. Moreover, it takes time and effort when it comes to present these visualizations to a bigger audience. We all know how to make Bar-Plots, Scatter Plots, and Histograms, yet we don’t pay much attention to beautify them. This hurts us - our credibility with peers and managers. You won’t feel it now, but it happens.
Chatbots  aren't as difficult to make as You Think

Chatbots aren't as difficult to make as You Think

Chatbots are the in thing now. Every website must implement it. Every Data Scientist must know about them. Anytime we talk about AI; Chatbots must be discussed. But they look intimidating to someone very new to the field. We struggle with a lot of questions before we even begin to start working on them. Are they hard to create? What technologies should I know before attempting to work on them?

Why Sublime Text for Data Science is Hotter than Jennifer Lawrence?

Just Kidding, Nothing is hotter than Jennifer Lawrence. But as you are here, let’s proceed. For a practitioner in any field, they turn out as good as the tools they use. Data Scientists are no different. But sometimes we don’t even know which tools we need and also if we need them. We are not able to fathom if there could be a more natural way to solve the problem we face.
NLP  Learning Series: Part 4 - Transfer Learning Intuition for Text Classification

NLP Learning Series: Part 4 - Transfer Learning Intuition for Text Classification

This post is the fourth post of the NLP Text classification series. To give you a recap, I started up with an NLP text classification competition on Kaggle called Quora Question insincerity challenge. So I thought to share the knowledge via a series of blog posts on text classification. The first post talked about the different preprocessing techniques that work with Deep learning models and increasing embeddings coverage.

NLP Learning Series: Part 3 - Attention, CNN and what not for Text Classification

This post is the third post of the NLP Text classification series. To give you a recap, I started up with an NLP text classification competition on Kaggle called Quora Question insincerity challenge. So I thought to share the knowledge via a series of blog posts on text classification. The first post talked about the different preprocessing techniques that work with Deep learning models and increasing embeddings coverage. In the second post, I talked through some basic conventional models like TFIDF, Count Vectorizer, Hashing, etc.
What my first Silver Medal taught me about Text Classification and Kaggle in general?

What my first Silver Medal taught me about Text Classification and Kaggle in general?

Kaggle is an excellent place for learning. And I learned a lot of things from the recently concluded competition on Quora Insincere questions classification in which I got a rank of 182/4037. In this post, I will try to provide a summary of the things I tried. I will also try to summarize the ideas which I missed but were a part of other winning solutions. As a side note: if you want to know more about NLP, I would like to recommend this awesome course on Natural Language Processing in the Advanced machine learning specialization.
