Welcome to the tutorial on Neural Network Implementation! In this guide, we'll explore the basics of implementing a neural network from scratch. A neural network is a series of algorithms that can recognize underlying relationships in a set of data through a process that mimics the way the human brain operates.

Basics of Neural Networks

A neural network consists of layers of interconnected nodes, or "neurons," that work together to process information. The network can be used for various tasks, including classification, regression, and clustering.

Key Components

  • Input Layer: Receives the input data.
  • Hidden Layers: Perform computations using weights and biases.
  • Output Layer: Produces the final output.

Learning Process

Neural networks learn by adjusting the weights and biases in each layer. This process is known as backpropagation.

Implementing a Neural Network

To implement a neural network, we'll need to:

  1. Initialize the Network: Set up the layers, neurons, and initial weights.
  2. Forward Propagation: Pass the input data through the network to generate an output.
  3. Backpropagation: Adjust the weights and biases based on the error between the predicted and actual outputs.
  4. Training: Repeat the forward and backpropagation steps for a number of iterations to train the network.

Example Code

Here's an example of a simple neural network implementation in Python.
