Underwater Robotics

Definition

Convolutional neural networks (CNNs) are a class of deep learning algorithms specifically designed to process structured grid data such as images. They utilize convolutional layers that apply filters to the input data, allowing the network to automatically and adaptively learn spatial hierarchies of features. This makes CNNs particularly effective for tasks involving visual data, making them crucial in applications like navigation and control systems in robotics.

5 Must Know Facts For Your Next Test

  1. CNNs typically consist of multiple layers, including convolutional layers, pooling layers, and fully connected layers, which work together to progressively extract higher-level features from the input images.
  2. One of the main advantages of CNNs is their ability to reduce the number of parameters needed compared to fully connected networks, making them less prone to overfitting and more efficient for image classification tasks.
  3. CNNs can effectively handle translation invariance, meaning they can recognize objects in images regardless of their position within the frame.
  4. The use of data augmentation techniques, such as rotation and scaling, helps improve the robustness of CNNs by providing more diverse training samples.
  5. Transfer learning allows pre-trained CNN models to be fine-tuned on specific tasks, saving time and computational resources while achieving high performance in new applications.
