What is a Deep Neural Network?

A deep neural network (DNN) has multiple hidden layers between the input and output. These extra layers allow the network to learn more abstract and complex patterns.

✅ Key Points

  • Structure: Input → Hidden Layer 1 → Hidden Layer 2 → ... → Hidden Layer N → Output

  • Can handle large and complex datasets.

  • Used in modern AI applications like image recognition, NLP, and speech recognition.

  • Requires high computational power and large amounts of data.
