45. Your First Neural Network in PyTorch
Pahila net: Sequential, loss, Adam, train loop. Mauli-style tiny table. zero_grad → backward → step.
What you will learn in this chapter
- Build a tiny Sequential net
- Loss and optimizer
- Train loop
- Predict with sigmoid
- Practice before DL vs ML
Fictional data
Blinkit / Amazon Now / Mauli Dairy figures in this chapter are fictional sample data for learning only. They do not show real company numbers. People names are for practice; e-mails use example.com.
