Course Introduction：In machine learning, features refer to measurable and quantifiable properties or characteristics of an object, person, or phenomenon. Features can be roughly divided into two categories: sparse features and dense features. Sparse Features Sparse features are those features that occur discontinuously in a dataset and have most values ​​equal to zero. Examples of sparse features include the presence or absence of specific words in a text document or the occurrence of specific items in a transaction dataset. They are called sparse features because they have few non-zero values ​​in the data set and most of the values ​​are zero. Sparse features are common in natural language processing (NLP) and recommender systems, where data are often represented as sparse matrices. Working with sparse features can be more challenging because they often have many zero or near-zero values, which makes them computationally
