Data cleansing is the process of identifying and resolving corrupt, inaccurate, or irrelevant data. This critical stage of data processing — also referred to as data scrubbing or data cleaning — boosts the co
Data pipelines are the backbones of data architecture in an organization. Here's how to design one from scratch.
The term “data processing” was first coined with the rise of computers in the 1950s. However, people have been processing data for far longer than that. From the first bookkeepers, thousands of years ago, to thethe “big data” of today’s world, data is and always has been of grea...
The return type offit_transformisnumpy.ndarray, so we convert it into a dataframe bypd.DataFrameand stored it in a variable. Then, to join it in our original data frame, we can usepd.concatthe function that concatenates 2 different data frames. We have usedaxis=1, which means it has t...
An effective chart appliesdata visualization design principlesthat take advantage ofpre-attentive visual processing. This style of visualization is essentially a hack for the brain to understand large amounts of information quickly. However, interactions such as filtering, selecting, or rerendering points...

Why is data preparation important? One of the main purposes of data preparation is to ensure that raw data being processed for analytics uses is accurate and consistent. Data is commonly created with missing values, inaccuracies or other errors. Also, separate data sets often have different format...

The merge/purge is one of the most important data processing functions that direly impacts a business’s marketing objectives, tasks and goals. It’s obvious that with rising data complexities, you’d want to optimize your lists and records to maximize on customer marketing, service, and person...
Augmented data: This involves creating modified versions of existing data to increase dataset diversity. For example, in image processing, applying transformations like rotations, flips, or color adjustments to existing images can help models generalize better. Synthetic data: This refers to artificially...
