Summary of Changes

Hello @Kayyuri, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the clarity of the Dense layer's documentation by explicitly addressing the use of the use_bias parameter in conjunction with batch_normalization. The update aims to help users understand when it is appropriate to disable the bias term in a Dense layer, thereby preventing redundant parameters and promoting more efficient model design when batch normalization is subsequently applied.

Highlights

  • Documentation Update: The documentation for the Dense layer in Keras has been updated to provide clearer guidance on the use_bias parameter.
  • Batch Normalization Interaction: A specific clarification has been added regarding the interaction between use_bias and batch_normalization, advising that use_bias can be set to False when batch_normalization is applied, as batch normalization includes its own parameters for handling shifts.

Code Review

This pull request aims to clarify the usage of the use_bias parameter in the Dense layer when it is followed by a BatchNormalization layer. The intention is good, but the added documentation has some grammatical errors and lacks clarity. I've provided a suggestion to improve the wording, making it more accurate and easier to understand, while also adhering to the documentation style.
