Deep Learning Systems
In the context of deep learning, particularly convolutional neural networks (CNNs), a kernel is a small matrix used to apply convolution operations to input data. It scans over the input to extract features by performing element-wise multiplication and summing the results, allowing the network to learn spatial hierarchies and important patterns within the data. The kernel plays a critical role in determining how the network interprets various aspects of the input, influencing the subsequent layers such as pooling and fully connected layers.
congrats on reading the definition of kernel. now let's actually learn it.
