name 'regularizers' is not defined

The term 'regularizers' is often used in the context of machine learning, specifically in relation to regularization techniques that are used to prevent overfitting in models. However, if you are encountering an error message that says "name 'regularizers' is not defined," it is likely that you are trying to use this term in a programming context without first defining it.

In order to use regularizers in your code, you will first need to import the necessary module or library that contains the regularizers you want to use. For example, in TensorFlow or Keras, you might import the regularizers module like this:

from tensorflow.keras import regularizers

Once you have imported the regularizers module or library, you can then use the specific regularization techniques provided by that module in your code. For example, you might use L1 regularization like this:

model.add(Dense(64, input_dim=64, activation='relu', kernel_regularizer=regularizers.l1(0.01)))

In general, if you encounter an error message that says "name 'X' is not defined," it means that you need to define X before you can use it in your code. This might involve importing a module or library, defining a function or variable, or otherwise setting up the necessary infrastructure for your code to work properly.
