Web24 de jul. de 2024 · Specially, in each hierarchical receptive field block (HRFB), we apply standard convolutions with different kernel sizes and dilated convolutions with different dilation factors to adaptively obtain multi-scale features. Meanwhile, to ease the training process and make the model focus on the prediction of image details ... WebFirst, an input image is fed to the network. Filters of a given size scan the image and perform convolutions. The obtained features then go through an activation function. Then, the output goes through a succession of pooling and other convolution operations. As you can see, features are reduced in dimension as the network goes on.

In this paper, we propose a model of learning in complex cells based on the Bienenstock, Cooper, and Munro (BCM) rule. We demonstrate that properties of receptive fields of complex cells can be learned using this biologically plausible learning rule.
