When do we use each method?

Our course came to its end. Now you are in a position to choose between the most well-known dimensionality reduction techniques for a range of different data types. You have solved a number of challenging code exercises and you are able to use R for solving a group of data science problems related to datasets with high dimensionality. Our last multiple choice exercise asks you to answer the simple (by now) but critical question that you will be facing many times in the future. When do we use each of the taught methods?
