R Program to find elements that are present in two given data frames
In this Learn by Coding example, we are explaining how to write an R program to find elements that are present in two given data frames. Here we are using a built-in function intersect(). The function intersect() helps to calculate the intersection of subsets of a probability space and the comparisons are made row-wise. The syntax of this function is,

Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning: This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
