Why is batch size important in machine learning?

Batch size refers to the number of training examples utilized in one iteration. It's crucial because it affects the model's performance and training speed.

What happens if the batch size is too small?

If the batch size is too small, the model may take longer to converge and can lead to noisy gradient estimates, which might affect learning.

And what about a batch size that's too large?

A large batch size can speed up training but may lead to poorer generalization and can require more memory, potentially causing out-of-memory errors.

Is there an optimal batch size?

The optimal batch size often depends on the specific dataset and model architecture, but common sizes range from 32 to 256.

How can I determine the best batch size for my model?

You can experiment with different batch sizes and monitor the model's performance on validation data to find the best fit.
