A Convolutional Neural Network (CNN) is a neural network architecture that is specifically designed for processing structured grid data such as images. CNNs have become the state-of-the-art approach for image recognition, classification, and segmentation tasks due to their ability to learn spatial hierarchies of features directly from the input data.
In this tutorial, we will cover the basics of CNNs and how to implement a simple CNN using HTML tags. Before we dive into the HTML code, let’s review the key components of a CNN:
-
Convolutional Layer: The core building block of a CNN, the convolutional layer applies a set of learnable filters (kernels) to the input data to extract features. Each filter scans the input data with a sliding window and generates feature maps that capture patterns in the data.
-
Pooling Layer: The pooling layer reduces the spatial dimensions of the feature maps by aggregating neighboring pixels. This helps to reduce computational complexity and allows the network to focus on the most important features.
-
Activation Function: The activation function introduces non-linearity into the network, allowing it to learn complex patterns and relationships in the data. Common activation functions include ReLU (Rectified Linear Unit) and Sigmoid.
- Fully Connected Layer: The fully connected layer processes the high-level features extracted by the convolutional layers and generates the final output. This layer connects every neuron from the previous layer to every neuron in the current layer.
Now, let’s create a simple CNN using HTML tags:

<h1>Simple Convolutional Neural Network</h1>

<!-- Fully Connected Layer -->

</div>
</body>
</html>In this HTML code, we have defined the four key components of a CNN using div elements:
- Input Layer: Displays the input image that will be processed by the CNN.
- Convolutional Layer: Shows the filter and feature map generated by the convolutional layer.
- Pooling Layer: Displays the pooled feature map generated by the pooling layer.
- Fully Connected Layer: Outputs the final class label predicted by the CNN.
To implement a complete CNN, you would need to add CSS styling and JavaScript functionality to handle the processing of the input data through the different layers of the network. Additionally, you would need to train the CNN on a dataset using a deep learning framework such as TensorFlow or PyTorch.
I hope this tutorial gives you a better understanding of Convolutional Neural Networks and how they can be implemented using HTML tags. Happy coding!
