Subset refers to a category of trends that involve mathematical and statistical concepts. It's like going back to high school, but with fewer bullies and more brain power. From supervised learning to sampling probability, these trends all center around understanding and analyzing data. The common theme here is taking a smaller section of data and using it to make conclusions about the larger picture. It's like analyzing a slice of cake to determine how the entire cake tastes. These trends are perfect for those who like to see patterns and trends, and love diving deep into data. So, whether you're a math nerd or just looking to impress your boss with some fancy statistical jargon, Subset has got you covered.
