What is equal-width discretization? Let’s say a column in a dataset contains continuous numerical values, such as age, weight, price, etc. Now, we want to convert the continuous numerical values into discrete intervals. This process of converting continuous numerical...
Let’s say we have a dataset. The dataset has several columns. And we want to transform different columns differently. For example, we may want to use Standard Scaler for one column, and Min-Max Scaler for another column. One way to do it is to use the Standard Scaler...
In frequency encoding, each value in a categorical column is replaced with the total count or the frequency of the value. For example, let’s say a categorical column has 10 rows. The value “A” occurs 4 times, “B” occurs 3 times, “C” occurs 2 times and “D” occurs 1...
What is One-Hot Encoding? Let’s say a column in a dataset contains categorical values. There are three different values in the categorical column. Let’s say, these values are “A”, “B”, and “C”. If we perform One Hot Encoding on the data of the column, then three...
What is ordinal encoding? A categorical variable contains categorical data, such as name, gender, address, etc. There are different types of categorical variables. A nominal categorical variable contains categorical data that cannot be ranked over each other. For...
