What are the applications of lambda functions in machine learning?

Lambda functions are anonymous functions that can be used for various tasks in machine learning, such as data preprocessing, feature extraction, and model evaluation.

Can you give me an example of how to use a lambda function in data preprocessing?

Sure! You can use a lambda function to apply a transformation to a dataset, like normalizing values. For example, data['column'] = data['column'].apply(lambda x: (x - min(data['column'])) / (max(data['column']) - min(data['column']))).

Are there any specific libraries in Python that support lambda functions?

Yes, libraries like Pandas and NumPy support lambda functions extensively, allowing for efficient data manipulation and analysis.

What are the advantages of using lambda functions over regular functions?

Lambda functions are more concise and can be defined in a single line, making your code cleaner and easier to read, especially for simple operations.
