What is Data Transformation?
Data Transformation is the process of converting data from one format or structure to another, with the goal of making it more suitable for analysis or machine learning. It involves a set of techniques for cleaning, organizing, and manipulating data, with the goal of improving its quality, usability, and relevance. Data Transformation is an important step in the data science process, as it can have a significant impact on the accuracy and effectiveness of the resulting models.
What does Data Transformation do?
Data Transformation converts data from one format or structure to another, making it more suitable for analysis or machine learning:
- Cleans data: Data Transformation cleans the data by removing duplicates, handling missing values, and correcting errors.
- Organizes data: Data Transformation organizes the data by grouping it into features and labels, and by creating new variables based on existing ones.
- Manipulates data: Data Transformation manipulates the data by performing mathematical operations, aggregations, or filtering, with the goal of extracting insights or creating new variables.
Some benefits of Data Transformation
Data Transformation offers several benefits for data science and machine learning:
- Improved accuracy: Data Transformation improves the accuracy of machine learning models by converting the data into a format that is more suitable for analysis.
- Reduced errors: Data Transformation reduces errors in the data, which can lead to more reliable results and insights.
- Improved efficiency: Data Transformation streamlines the data science process by eliminating unnecessary data and creating new variables that capture the relevant information.
