Description: High-level features in convolutional neural networks (CNNs) are abstract representations derived from raw data, such as images or audio signals. These features are fundamental to the functioning of CNNs, as they enable the network to identify complex and relevant patterns in the data. In the lower layers of a CNN, low-level features like edges and textures are extracted. As one moves to the upper layers, the features become more abstract and complex, allowing the network to recognize objects, faces, or even emotions. This hierarchical learning process is what makes CNNs particularly effective in various classification and detection tasks. High-level features are crucial for the model’s generalization, as they allow the network to apply what it has learned to new, unseen data. Additionally, these features can be visualized and analyzed to better understand how the network makes decisions, which is essential for improving the interpretability and trust in artificial intelligence models.
