What is the impact of optimizer choice in machine learning?

The choice of optimizer can significantly affect the convergence speed and final performance of a model. Different optimizers have unique characteristics that can lead to varying results.

Can you explain how different optimizers like SGD and Adam differ?

Sure! SGD (Stochastic Gradient Descent) updates weights based on the gradient of the loss function, while Adam adapts the learning rate for each parameter based on first and second moments of the gradients, often leading to faster convergence.

Which optimizer would you recommend for a deep learning project?

It depends on the specific project, but Adam is often a good starting point due to its adaptive learning rate. However, experimenting with different optimizers is key to finding the best fit for your model.

Are there any scenarios where SGD might be preferred over Adam?

Yes, SGD can be preferred in scenarios where you want more control over the learning process, such as when fine-tuning a model or when working with very large datasets.
