What Is Data Science Methodology?
The Data Science Methodology is a resource for people who work in data science and are always looking for answers to a variety of problems. The procedure for solving a problem is described in Data Science Methodology. This is a cyclical process in which critical behavior guides business analysts and data scientists to respond appropriately.
- Business Understanding: Before a problem in the business sector can be solved, it must first be thoroughly understood. Business comprehension provides a solid foundation for easy query resolution. We should be clear about the problem we are attempting to tackle.
- Analytical comprehension: Based on the aforementioned business data, the analytical method to use should be determined. There are four types of approaches: descriptive (presents the current status and information), diagnostic (a statistical study of what is happening and why it is happening), predictive (predicts trends or the likelihood of future events), and prescriptive (prescribes actions) (how the problem should be solved).
- Data Requirements: The above-mentioned analytical approach specifies the data content, formats, and sources that must be acquired. During the data needs process, answers to queries such as “what,” “where,” “when,” “why,” “how,” and “who” should be found.
- Data Collection: Data may be gathered in any random format. As a result, the data gathered should be double-checked in light of the strategy chosen and the desired outcome. As a result, extra data may be collected if necessary, or data that is no longer needed may be discarded.
- Data Comprehension: Data comprehension answers the question, “Does the data obtained represent the problem to be solved?” This step may result in a return to the previous stage for rectification.
- For further understanding of this notion, consider two analogies. The first is to wash newly selected veggies, and the second is to just take what you wish to eat from the buffet. Washing veggies represents the removal of dirt, or undesired. items, from data. Noise reduction is carried out here. Putting just edible objects on the plate means that if we don’t require certain data, we couldn’t consider it for further processing. This entire procedure involves transformation, normalization, and so on.
- Modeling determines whether the data that is ready for processing is suitable or requires additional finishing and seasoning. This stage focuses on developing predictive and descriptive models.
- Model assessment occurs during the model creation process. It determines the quality of the model is evaluated as well as if it fits the business needs. It goes through a diagnostic measure phase (where the model performs as expected and where changes are needed) and a statistical significance testing phase (ensures proper data handling and interpretation).
- Deployment: The model is ready for commercial use after it has been thoroughly tested. The model’s resistance to the external environment and ability to outperform others is determined during the deployment step.
- Feedback is essential for developing the model and determining its effectiveness and impact. Defining the review procedure, tracking the record, measuring efficacy, and reviewing and improving are all steps in the feedback process.
After completing these ten stages, the model should not be left untreated; rather, it should be updated based on feedback and deployment. As new technologies emerge, new patterns should be investigated so that the model can continue to add value to solutions.
Data science education is in its early phases of growth; it is emerging as a self-sustaining subject that produces individuals with separate and complementary abilities to those in the computer, information, and statistical sciences.
