Deep Learning and Neural Networks

This practical guide takes you from the fundamentals to advanced levels of deep learning.

Deep learning has revolutionized machine learning, enabling systems to learn from complex data and solve problems previously considered impossible. This guide will walk you through the basics of neural networks, their architectures, and practical applications.

❌ Overly Deep/Wide Network

Start with a simple architecture and gradually increase complexity. Use regularization for complex models.

❌ Ignoring the validation set

Frequently asked questions

What is StepLR? It reduces by a fixed number?

StepLR: Reduces by a fixed number of epochs (e.g., by 10 times every 30 epochs)

What does ReduceLROnPlateau do? Does it reduce when the metric improves?

ReduceLROnPlateau: Reduces when the metric stops improving – this is the most popular approach.

What is CosineAnnealing? Does it change according to a cosine curve?

CosineAnnealing: Changes according to a cosine curve.

What is Warm-up? Does it start with a small LR and then increase?

Warm-up: Starts with a small LR and then increases it.
