Convolutional Neural Networks (CNNs) are a class of deep neural networks that are particularly effective for analyzing visual imagery. They are widely used in various fields such as image recognition, object detection, and natural language processing.
Introduction to CNNs
CNNs are inspired by the biological structure of the human visual system. They mimic the way the human brain processes visual information by using layers of interconnected neurons.
Key Components of CNNs
- Convolutional Layers: These layers apply various filters to the input image to extract features such as edges, textures, and shapes.
- Pooling Layers: These layers reduce the spatial dimensions of the feature maps, which helps to decrease the computational complexity and parameter size.
- Fully Connected Layers: These layers connect every neuron in the previous layer to every neuron in the current layer, similar to a traditional neural network.
CNN Example
Let's take a look at a simple CNN architecture for image classification:
- Input Layer: The input layer receives the raw image data.
- Convolutional Layer: The convolutional layer applies filters to the input image to extract features.
- Pooling Layer: The pooling layer reduces the spatial dimensions of the feature maps.
- Fully Connected Layer: The fully connected layer connects every neuron in the previous layer to every neuron in the current layer.
- Output Layer: The output layer produces the final classification result.
