Next Up: How Does The Predictive Analytics Work?
Once data collection is complete, the statistical model is activated and trained to generate predictions based on the provided or selected data. The entire process can be summarized in just 5 steps:
1. Define the problem of interest: What do we want to ask this electronic brain? The data provided will undoubtedly be in vast quantities, so we must have a clear idea of what we want to derive from it. The best products to sell at Christmas? A list of potential spammers or industrial spies? Geographical areas at higher risk of catastrophic events than others? The possibilities might seem as endless as the database we managed to create.
2. Organize the data: It depends on how good we were at collecting and archiving them in historical records, but the more data we have, the more organized we must be. Even before developing Predictive Analytics models, we must set up the data in such a way that they are easily accessible and readable with centralized access that is valid for the entire system.
3. Level and process the data: Raw data itself is essential and highly valuable. But while it might be okay to view them individually, perhaps by saving them in an Excel spreadsheet on your computer, they might need to be "rearranged" for easy integration into a central system. They may require cleaning, leveling, and processing in such a way that the settings match in a single common flow.
4. Model development: This is undoubtedly the work of an expert technician. We should let Data Scientists do their work, utilizing a series of tools and techniques to develop predictive models depending on the problem we have chosen. As mentioned earlier, the most commonly used models are based on machine learning systems, artificial intelligence, and statistical models.
5. Data validation and distribution: After the initial decisions, accumulation, cleaning, and data processing, and especially after developing predictive models, we are ready to make them usable for anyone we think needs them. To make things easier, these models are usually transformed into web interfaces, such as applications or a website, much more user-friendly and easy to consult.
