Most people think data science is smart people doing very smart stuff. Well that’s not it. Data science is just another subject involving its own bit of subtle complexities that has to be handled with knowledge and an innovative approach. JUST LIKE COOKING.
Cooking is art and science. So is Analytics. Both start from getting the right ingredients. No matter how many spices and cooking techniques you apply, the dish won’t…Continue

I’m going to keep this tutorial light on math, because the goal is just to give a general understanding.
The idea of Monte Carlo methods is this—generate some random samples for some random variable of interest, then use these samples to compute values you’re interested in.
I know, super broad. The truth is Monte Carlo has a ton of different applications. It’s…Continue
Random Forest is a machine learning algorithm used for classification, regression, and feature selection. It's an ensemble technique, meaning it combines the output of one weaker technique in order to get a stronger result.
The weaker technique in this case is a decision tree. Decision trees work by splitting the and re-splitting the data by…Continue

In my last post, I have explained about MSE, today I will explain the variance & bias trade-off, Precision recall trade-off while assessing the model accuracy.
Variance refers to the amount by which the estimated output (f) would change if we estimated it (f) using a different training dataset. Since the training data is used to fit the statistical learning method, different training sets will…

Many take inventory of their data and find out they have terabytes of data lying around. Surely something should be done with that, so here’s how we see a lot of companies going about implementing ‘something’ for their Big Data.

The Voice is a very successful show that runs in 28 countries around the globe. The basic concept in each version is the same: Four famous singers act as coaches. They have to select a team of vocalists through an audition process. The teams compete internally through a process of competitive elimination, until one vocalist per coach enters the Finals. There, the best vocalist of the four is declared 'The…Continue

At BigML, we know what it takes to develop code. One of the things we love is having a sandbox - an environment to play around in, free of charge, while developing our apps. So we hurried to create a free machine learning sandbox. Today we are proud to announce: BigML’s development mode!
Here’s how it works. If you don’t have an account yet,…Continue
