Cost function of neural network is non-convex? - Cross Validated
Web12 de mar. de 2024 · Loss functions in artificial neural networks (ANNs) are used to quantify the error produced by the model on a given dataset. ANNs are trained via the minimisation of a given loss function. Therefore, loss function properties can directly affect the properties of the resulting ANN model [ 1, 4 ]. WebA training method for a robust neural network based on feature matching is provided in this disclosure, which includes following steps. Step A, a first stage model is initialized. The first stage model includes a backbone network, a feature matching module and a fullple loss function. Step B, the first stage model is trained by using original training data to obtain … book club illustration
