Loss function reflectivity

WebWhereas the real part of the static dielectric function shifts to 13.5 eV for FeCrHfSn alloy; this suggests a negative value of ε 1 (ω), in the energy band 0–0.3 eV demonstrating the loss of light transit of FeCrHfSn alloy. Web4 de ago. de 2024 · A loss function is a function that compares the target and predicted output values; measures how well the neural network models the training data. When training, we aim to minimize this loss between the predicted and target outputs.
