The neural network is a model. The deep learning method can effectively solve the problem that the neural network with many layers is difficult to learn. In order to allow the multi-layer neural network with many layers to be trained, a series of new structures and new methods have been developed. - The commonly used loss function for classification problems: - Cross-Entropy Loss Function (also known as the softmax loss function): It can be used to solve multi-classification problems by converting the output into a probability form through exponentiation. - Hinge loss function: Under normal circumstances, the effect of the cross-entropies loss function is better than that of the Hinge loss function. - Ramp loss function: It has strong anti-interference ability against outlier or noise. It is a robust loss function that will intercept areas with large errors. - Large margin loss function: While ensuring the correct classification, it also meets the requirements of increasing the differences between classes, improving the distinguishing ability of the features and preventing the network from overfitting; - [Central loss function: While ensuring the correct classification, it also reduces the differences within the class and improves the distinguishing ability of the features.] - The commonly used loss function for the return problem: - L1 loss function: It measures the deviation between the predicted value and the actual value. - l2 loss function: the effect is better than l1; - Tukey's Biweight loss function was a robust loss function. - The loss function of other tasks: The KL-Dispersion loss function, which measures the difference between the sample marker distribution and the real marker distribution, can be used for age estimation, etc. ** X. Consecutive neural networks ** 1. [Question: What is a Consecutive neural network?] Please explain the meaning of the convolutions. - ** Answer **: In Consecutive neural networks,"Consecutive" and "neural network" are understood separately. Convolutions meant that the neural network no longer processed the input information of each pel, but processed each small pel region on the image. This approach strengthened the continuity of the image information, allowing the neural network to see the image instead of a point. At the same time, it also deepened the neural network's understanding of the image. "A Short History of the Future: Legends of the Intelligent Era" was equally exciting.
