What Do They Do?

  • Imagine you are buying a phone online.
  • The App gives you suggestion like phone cover, head set, charger that can be bought together.
  • Have you ever wondered how this recommedations appear?
  • This is done with the help of a machine-learning model that analyses the data from the App and uses this to predict what people may be interested.
  • The person who builds this model is called a Data Scientist.
  • 👉 In simple words: Data Scientists use data to find patterns and build AI models that make predictions .
