How are filters learned in a convolutional neural network?

Saturday, 05 August 2023 by EITCA Academy

In the realm of convolutional neural networks (CNNs), filters play a important role in learning meaningful representations from input data. These filters, also known as kernels, are learned through a process called training, wherein the CNN adjusts its parameters to minimize the difference between predicted and actual outputs. This process is typically achieved using optimization
