Difference Between Neural Network and Deep Neural Network

A Neural Network is a computational model inspired by the human brain, consisting of interconnected layers of neurons that process data. A Deep Neural Network (DNN) is a type of neural network with multiple hidden layers, allowing it to learn complex patterns from data.

Key Differences:

Feature	Neural Network	Deep Neural Network
Number of Layers	Typically 1-2 hidden layers	Multiple hidden layers (deep architecture)
Complexity	Handles simple tasks	Handles complex tasks like image recognition, NLP
Training Time	Faster training	Requires more computational power
Performance	Limited feature extraction	Can learn hierarchical features
Use Cases	Basic classification, regression	Advanced AI applications (self-driving cars, speech recognition)

Why Deep Neural Networks Work Better?

More layers allow hierarchical feature learning (e.g., detecting edges → shapes → objects in images).
Better generalization for complex datasets.
Improved accuracy in deep learning tasks.
