👉 Spadefuls are a type of mathematical operation that is used in digital signal processing and computer graphics. They are similar to convolutional neural networks (CNNs) but have some differences. In the context of DSP, a spadeful operation is an operation that takes a sequence of values from the input data and produces a new output value based on a set of rules or parameters. The rule can be any function or formula, and it doesn't necessarily have to be linear. For example
