returns the quantile loss for the trained quantile neural network regression model Mdl. The function uses the predictor data in the table Tbl and the response values in the ResponseVarName table variable. For more information, see Quantile Loss....
We introduced the existing methods and the core idea of representing the structurally unknown dynamics of a differential equation system by a deep neural network, and proposed a novel objective function formulation, which combines strategies from simulation-based inference and classical approximation ...

Step 1: Choose a Suitable Loss Function: Determine the type of problem you’re working on (e.g.,regression, binary classification, multiclass classification) and choose a loss function appropriate for that problem. You can also design a custom loss function tailored to your specific needs. ...
2.1. Regression loss function analysis In object detection tasks, regression loss functions fall into two main categories. The first category utilizes Ln norm regression losses, such as L1, L2, and Smooth-L1 losses. The second category employs Intersection over Union (IoU) regression losses, includ...
In this post, you have seen loss functions and the role that they play in a neural network. You have also seen some popular loss functions used in regression and classification models, as well as how to use the cross entropy loss function in a TensorFlow model. Specifically, you learned: ...
for my neural network, it's very important to not have a high error-range, i.e. a higher mean-error is better than a higher error-range. That's why I'd like to implement a different loss function. My network has a regressionLayer Output which computes loss based on mean squared ...
