Splitting variable in big data

Big data

Big data is a term that describes the large volume of data – both structured and unstructured – that inundates a business on a day-to-day basis. But it’s not the amount of data that’s important. It’s what organizations do with the data that matters. Big data can be analyzed for insights that lead to better decisions and strategic business moves.

What is big data?

Most people have heard of “big data,” but few know exactly what it is. Big data is a term used to describe the exponential growth, availability and use of information. It’s being generated all around us, by everything from weblogs and social media to sensors and digital images. But handling big data presents challenges for organizations that want to take advantage of its opportunities.

To get a better handle on big data, it can be helpful to think of it in terms of the 3 V’s:

Volume: The first “V” stands for volume. This is the sheer amount of data that is being generated every day. For example, Facebook alone generates nearly 2.5 billion pieces of content (including status updates, photos, videos and links) each day.*

Velocity: The second “V” stands for velocity, which refers to the speed at which this data is being generated and collected. For example, studies have shown that tweets about a brand are often posted within minutes of an event or customer experience happening.**

Variety: The third “V” stands for variety, which refers to the different types of data that are being collected (e.g., text, images, video, audio). For example, a single customer service interaction could involve text from an email or chat conversation, audio from a phone call and images from a web camera.*

To make sense of all this data — and put it to good use — organizations need new technologies as well as new skills and processes.*

Splitting variable

we will discuss about splitting variable. Splitting variable is very important in big data. It is used to split the data into two parts. The first part is training data and the second part is test data.

Why is it important to split variable in big data?

In big data, it is important to split variables for a number of reasons. First, it allows for parallel processing, which can help speed up the analysis. Second, it can help to reduce the size of the data set, making it easier to work with. Finally, it can help to improve the accuracy of the results.

How to split variable in big data?

In big data, it is often necessary to split a variable into multiple pieces. This can be done for a number of reasons, including:

-To improve performance
-To reduce the size of the data
-To make the data easier to work with

There are a few different ways to split a variable in big data. The most common methods are:

-Bucketing: This method involves dividing the data into equal-sized groups, or buckets. This is often used when working with numerical data.
-Hashing: This method involves assigning each piece of data to a specific group, or hash. This is often used when working with non-numerical data.
-Random sampling: This method involves randomly selecting pieces of data from the original dataset. This can be used for both numerical and non-numerical data.


We have seen that there are a number of ways to split variables in big data sets, and each has its own advantages and disadvantages. In general, however, it is best to use a method that is both computationally efficient and able to handlemissing values. The methods described here are all able to do both of those things.
