Description: An activation vector in the context of convolutional neural networks is a numerical representation that captures the activated outputs of a specific layer within the network. This vector is generated after applying an activation function to the layer’s outputs, allowing the neural network to learn complex patterns in the input data. Each element of the vector corresponds to a neuron in the layer, and its value indicates the degree of activation of that neuron, i.e., how relevant the feature it has detected in the input is. Activation vectors are fundamental to the backpropagation process, where the weights of the network are adjusted based on errors in predictions. Additionally, these vectors allow for the interpretation of the features learned by the network, facilitating the understanding of how the network makes decisions. In summary, the activation vector is a key component that enables convolutional neural networks to efficiently and effectively process and learn from complex data, such as images and signals.
