Practical Business Python Introduction In many practical Data Science activities, the data set will contain categorical variables. These variables are typically stored as text values which represent various traits. Some examples include color (“Red”, “Yellow”, “Blue”), size (“Small”, “Mediu...
This exercise shows how to convert categorical variables into numerical values using label encoding for machine learning models. Sample Solution: Code : importpandasaspdfromsklearn.preprocessingimportLabelEncoder# Load the datasetdf=pd.read_csv('data.csv')# Initialize the LabelEncoderle=LabelEncoder()# ...

Categorical variables: These variables portray the category or groups in the data values. Example: [apple,mango,berry] In a dataset, we come across data that contains the categorical data in the form of groups such as [apple, berry, mango]. In order to represent each category of the data...
These categorical variables pose a challenge for machine learning algorithms. Implementation of One-Hot Encoding Here, we will implement One-Hot Encoding using Python. Let's import the libraries. import pandas as pd #for one-hot encoding we will import OneHotEncoder from the sklearn from sk...
