Webb8 okt. 2024 · 1. Pooling Layer. Other than convolutional layers, ConvNets often also use pooling layers to reduce the size of the representation, to speed the computation, as well … WebbThe pooling layer serves to progressively reduce the spatial size of the representation, to reduce the number of parameters and amount of computation in the network, and hence …

WebbInstead, we reduce the number of qubits by performing operations upon each until a specific point and then disregard certain qubits in a specific layer. It is these layers where we stop performing operations on certain qubits that we call our ‘pooling layer’. Details of the pooling layer is discussed further in the next section. WebbIn the practical application scenarios of safety helmet detection, the lightweight algorithm You Only Look Once (YOLO) v3-tiny is easy to be deployed in embedded devices because its number of parameters is small.
