As a blogger, I often come across the question, "What is data science's synonym?" In simple terms, data science can be referred to as 'knowledge discovery' or 'data mining.' It's basically the process of extracting valuable information from massive amounts of data using various techniques, tools, and algorithms. I believe that understanding data science as 'knowledge discovery' really highlights its purpose - to discover hidden patterns and insights within data that can be used to make informed decisions. So, the next time you think of data science, remember that it's all about discovering the knowledge hidden within the data we collect.
