What is the Adam optimizer in deep learning?

The Adam optimizer is an adaptive learning rate optimization algorithm used in training deep learning models. It combines the advantages of two other extensions of stochastic gradient descent.

How does it differ from traditional gradient descent?

Unlike traditional gradient descent, which uses a fixed learning rate, Adam adjusts the learning rate for each parameter individually based on the first and second moments of the gradients.

What are the benefits of using Adam?

Adam is known for its efficiency and effectiveness, especially in handling sparse gradients and noisy problems. It often converges faster than other optimizers.

Are there any drawbacks to using Adam?

One potential drawback is that Adam can sometimes lead to suboptimal solutions in certain scenarios, particularly with non-convex problems.
