3. Introduction to Neural
Networks
Neural networks are a fundamental component of artificial intelligence,
inspired by the biological neural networks in the human brain. They are
composed of interconnected nodes, called neurons, that process and
transmit information through weighted connections, similar to how neurons in
the brain communicate.
Neural networks are crucial in the field of AI as they enable machines to learn
and adapt, allowing for the development of intelligent systems that can
perform complex tasks such as image recognition, natural language
processing, and predictive analytics.

4. Key Components of Neural Networks
1. Neurons (Nodes): The basic processing units within a neural network, inspired by the structure of the
human brain.
2. Weights: Adjustable parameters that determine the strength of connections between neurons,
allowing the network to learn complex relationships.
3. Biases: Additional parameters that provide flexibility and control the activation of neurons, enabling the
model to capture non-linear patterns.
4. Layers: The hierarchical structure of a neural network, consisting of:
• Input Layer: Receives the initial data
• Hidden Layers: Perform feature extraction and transformation
• Output Layer: Generates the final predictions or classifications

5. How Neural Networks Work
1
Forward Propagation
Neural networks process data by
feeding it through the network from the
input layer to the output layer, allowing
the model to make predictions.
2 Loss Calculation
The network compares its output to the
true values, calculating a loss function
that measures the error or discrepancy
between the predicted and actual
outputs.
3
Backpropagation
Using the calculated loss, the network
adjusts the internal weights and biases
to minimize the errors, gradually
improving the model's accuracy. 4 Iteration
This cycle of forward propagation, loss
calculation, and backpropagation is
repeated many times, allowing the
neural network to continually refine its
understanding and performance.
