Data Acquisition/Acquiring Data


              Data acquisition, also known as acquiring data, refers to the procedure of gathering data like raw facts, figures or
              statistics from relevant sources either for reference or for analysis needed in AI projects. This involves searching

              for datasets suitable for training AI models. The process typically comprises three key steps and plays a crucial
              role in obtaining and preparing data for analysis.

              For example, to collect data for making a CV model for a self-driving car.

              The three key steps involved in data acquisition are given below:

              Step 1: Data Discovery
              Data discovery is about hunting for valuable information in different places, checking if it’s good quality, and
              making sense of what we find. In the above example:

              ●  We will require pictures of roads and the objects on roads.
              ●  We can search and download this data from the Internet.

                                                                                                    Cars
