A Convolutional Neural Network (CNN), also known as ConvNet, is a specialized type of deep learning algorithm mainly designed for tasks that necessitate object recognition, including image classification, detection, and segmentation. CNNs are employed in a variety of practical scenarios, such as aut...
we have developed a convolutional neural network algorithm for multi-wavelength oximetry, showing a greatly improved calculation performance in comparison to previously reported techniques. The algorithm is calibration free, performs sensing of the four main hemoglobin conformations with no prior knowledge of...
卷积神经网络Convolutional Neural Networks In the previous post, we figured out how to do forward and backward propagation to compute the gradient for fully-connected neural networks, and used those algorithms to derive the Hessian-vector product algorithm for a fully connected neural network....
