What are the potential issues with label encoding when dealing with a large number of categories in a column?
Label encoding is a common technique used in machine learning to convert categorical variables into numerical representations. It assigns a unique integer value to each category in a column, transforming the data into a format that algorithms can process. However, when dealing with a large number of categories in a column, label encoding can introduce

What is label encoding and how does it convert non-numerical data into numerical form?
Label encoding is a technique used in machine learning to convert non-numerical data into numerical form. It is particularly useful when dealing with categorical variables, which are variables that take on a limited number of distinct values. Label encoding assigns a unique numerical label to each category, allowing machine learning algorithms to process and analyze
How can non-numerical data be handled in machine learning algorithms?
Handling non-numerical data in machine learning algorithms is a important task in order to extract meaningful insights and make accurate predictions. While many machine learning algorithms are designed to handle numerical data, there are several techniques available to preprocess and transform non-numerical data into a suitable format for analysis. In this answer, we will explore
What is the purpose of encoding categorical data in the dataset preparation process?
Encoding categorical data is a important step in the dataset preparation process for machine learning tasks in the field of Artificial Intelligence. Categorical data refers to variables that represent qualitative attributes rather than quantitative measurements. These variables can take on a limited number of distinct values, often referred to as categories or levels. In order
