Data preparation is the process of collecting, blending, organizing, and structuring data to make data analysis outcomes better and fast. It is a critical component of data analysis as it weeds out all the unimportant and irrelevant elements in datasets. Good data preparation makes it possible to have data that do not have any calibration issues or discrepancies between datasets and thereby deliver insights that are on track.
Outsource2india has over two decades of experience in data preparation services. We are driven by a team of experts that primarily includes web technicians, database administrators, systems programmers, and analysts. The team takes care of the process of sifting, formatting, verifying, and keying data correctly so that only high-quality data is available for analysis. Our clients have leveraged our services to enhance efficiency and experience higher productivity, through accurate querying, profiling, reporting, and sharing of high-quality data.

As a well-known data preparation services providing company, we provide our range of services to our clients. Some of these services include -
Data Cleaning Services
Data generated from different sources contain a lot of unwanted elements that must be weeded out to ready it for proper analysis. Data cleaning services entails correcting common problems and other errors in data. It is an operation performed in the first stages of data preparation. The objective is to make the data less messy and more useful. We leverage our domain expertise to identify misfit, messy, corrupt, or erroneous data and rectify it.
Data tend to have wrong values, because of reasons such as incorrect typing, duplicated data, corrupted data, and so on. We correct or prepare the data using various methods such as statistics to differentiate normal data from outliers, identify redundant rows of data and remove them, mark empty values, impute blank values using learned model or statistics, remove duplicate rows and columns.
The objective of data analysis is to develop models that assist in making a prediction. Feature selection is a technique that involves picking a group of input features that can take the place of a variable target and assist build a prediction model. This is an important part of the preparation process as irrelevant or redundant variables can mislead the algorithms completely and lead to improper predictions.
Our feature selection technique banks on groups that use both the target variable and those that do not. The target variable is broken into further groups that select features automatically to fit the model; select features to develop the best performing model, and give a score to each feature so that a close performing subset can be selected. We primarily bank on statistical methods for finding input features. The right method is chosen based on the input variable data types and the best possible statistical methods to be used.
This is a preparation stage in which a change in the data variable distribution is carried out. We make use of a range of techniques to transform data and apply it to output and input variables. Data may be categorical or numeric, with variable subtypes for each. At this stage, a numeric variable is either converted to an ordinal variable or code as a categorical variable as Boolean variables or integers.
We specialize in Discretization Transform, Ordinal Transform, or One-Hot Transform. In Discretization transform, we code a numeric variable to ordinal. In Ordinal Transform we code a categorical variable into integer and in One-Hot Transform, we code a categorical variable into binaries.
This a type of data preparation in which new input variables from the available data are created. Our subject matter experts identify new features that can be interpreted from the data. A common approach is to create copies of numerical input variables with a simple mathematical operation, such as multiplying them with other input variables or raising them to power.
Feature engineering is carried out to add a broader context to a single observation. Sometimes it also helps in breaking down a complex variable and providing a more straightforward and simple perspective on the input data.
The dimensionality of Data is the number of input features for a dataset. In this type of data preparation, the inputs can be scaled up or scaled down to any number of variables to create volumes of different dimensions. Unlike feature selection, the input variables, in this case, are not directly related to the original input variables. This makes the projection a bit hard to interpret. The big advantage of this technique is that it removes linear dependencies between correlated variables.
As the name implies, dimensionality reduction is the reduction of data from a high-volume space into a low-volume space so that the low-volume representation has some relevant and meaningful properties of the original data. We leverage the two most common approaches to dimensionality reduction i.e., Principal Component Analysis (PCA) and Singular Value Decomposition (SVD).
Data Preparation Process We Follow
Our data preparation process depends on the kind of data that needs to be parsed and analyzed. The following steps define the process -
01. Define Problem
In this stage, we take the right steps to understand and define the data problem that is to be solved. We look for a problem that is clear, concise, and measurable. Understanding this in the right perspective helps in the ways to collect data, identify data patterns, and show correlations and predict outcomes
02. Data Collection
The problem identification process is followed by the collection of the right data. The collection is usually done from an existing data catalog or added ad-hoc. We collect data from first-party, second-party, and third-party sources. However, first-party data helps in laying the foundation of the dataset. Additional data types help in increasing the scale of the audience or help identify new target audiences
03. Decide on Approach
Once the problem is identified we choose the data science algorithms that need to be applied to data. This helps in roughly grouping the data into families such as two-class classification, multi-class classification, clustering, regression, dimensional reduction, reinforcement learning, etc.
04. Cleanse and Test Data
Data cleaning is the most time taking part in the data preparation process. But it is extremely crucial as it entails removing faulty data and filling in gaps. In this process, we remove extraneous data and outliers, replace all missing values, standardize data to a particular pattern, hide sensitive or private data entries, etc. After cleaning the data we test it for errors that might have cropped up and resolve the issue
05. Transform and Enrich Data
In this process of data preparation, we change the format to make the data consistent so that a well-defined outcome can be reached. This makes the data easily understood by a wider audience. An integral part of this stage is to add and connect data with other pertinent information to get deeper insights
06. Store data
After all the steps are addressed sequentially, the data is stored in a third party application. This is primarily a business intelligence tool thereby preparing the stage for processing and analysis of the data to take place
