Close your eyes and imagine that you live in a utopian world of perfect data. What do you see? What do you wish to see? Wait! are you imagining a flawless balanced dataset? A collection of data whose labels form a magnificent 1:1 ratio: 50% of this, 50% of that; not a bit to the left, nor a bit to the right. Just perfectly balanced, as all things should be. Now open your eyes, and come back to the real world. Well, this blog is all about how to handle imbalanced datasets.Continue reading “Handling Imbalanced Dataset with SMOTE in Python”
In my previous blog, I discussed how I landed up interning at Dentsu. I also discussed that I worked on scouting and building a POC for a cloud agnostic, open source API management tool/platform which could help in setting up API design, gateway, store, and analytics. In this blog, I will be jotting down my work in much more detail.
We will be exploring four API Management platforms, namely:Continue reading “A Survey of API Management Platforms”
My experience of hunting for and landing an internship in Singapore.

Shree Krishna says Fight for the sake of duty, treating alike happiness and distress, loss and gain, victory and defeat. Fulfilling your duty and responsibility in this way, you will never incur sin.
Arjuna’s was apprehensive that by killing his enemies, he would incur sin. Shree Krishna addresses his apprehension and he advises him to do his duty (dharma), without attachment to the fruits of his action. Such an attitude will release him from any sinful reactions.
This blog is in continuation to my NLP blog series. In the previous blogs, I discussed data pre-processing steps in R and recognizing emotions present in ted talks. In this blog, I am going to predict the ratings of the ted talks given by viewers. This would require Multi Class Classification and quite a bit of data cleaning and preprocessing. We will discuss each step in detail below. So, let’s dive in.
This post is in continuation with my NLP blog series. You might want to checkout my previous blog in which I discussed data pre-processing in R. In this blog, I will determine the emotions in Ted Talks. At the end, I will compute a HeatMap of emotions and talks to aid in our visualization.
So, without further ado, let’s dive in!
I have recently got my hands dirty with Natural Language Processing (NLP). I know, it’s a little late to the party but I am at least in the party!
To start with a general overview, I implemented quite a few tasks related to NLP including Text Classification, Document Similarity, Part-of-Speech (POS) Tagging, Emotion Recognition, etc. These tasks were made possible by implementing text pre-processing (noise removal, stemming) and text to features (TF-IDF, N-Grams, Topic Modeling, etc). I implemented these in both R and Python. So, I will try to jot down my experiences in both of these environments. Therefore, I will write this as a blog series, wherein each blog will discuss only one particular thing implemented in one particular environment.
I have recently shifted gears in my life. A shift to academics after spending quite sometime in the industry has been equally exciting and challenging at the same time. Even with all the diversity in the cohort of my own program (in terms of work experience and country of origin) along with a campus hustling with activities all day, I wanted to explore the communities ingrained deep within the culture of Singapore. A natural choice for me, was to look for meetups.
I came to know about Google’s Machine Learning Crash Course (MLCC) from Sundar Pichai’s tweet. I then enquired about it with some close acquaintances working in Google. I was soon pretty convinced of pursuing this course, after their good words about it and my own research on the course content. This post is going to be an account of my learnings from MLCC. I will structure the learnings in such a way that it will look more like a review. I will also include what I really liked about the course and things which I think they can possibly improve, if the creators are planning to update the course content. So, let’s get started!
At Truebil, I was fortunate enough to be given an opportunity to solve a unique engineering problem. We had already outsourced CRM development to a third party but I had to integrate the data flow to CRM from our product and back. I mentioned earlier that I was given a unique engineering problem because of the challenges it posed. The challenge didn’t lie in the CRM integration alone, but the fact that Truebil has umpteen number of in-house products which spawn data close to about 1 Million data streams per hour. Besides building a bastion of such magnitude, I knew that it would be equally challenging to work with three different verticals and stakeholders. This post is going to be an account of my experiences dealing with two things. First, how Truebil catered to the transfer of a million JSON data stream to and from CRM without hampering its operations and customer support. The second experience deals in the art of working with different verticals. Not that I have mastered the art or something, but I will share my own experiences and learnings in this post.
