In the discrete setting, a weig When working on a Machine Learning or a Deep Learning Problem, loss/cost functions are used to optimize the model during training. The objective is almost always to minimize the loss function. The lower the loss the better the model. Cross-Entropy loss is a most important cost function. It is used to optimize classification models.and cost-sensitive re-weighting. In re-sampling, the number of examples is directly adjusted by over-sampling (adding repetitive data) for the minor class or under-sampling (re-moving data) for the major class, or both. In cost-sensitive re-weighting, we inﬂuence the loss function by assigning 1 arXiv:1901.05555v1 [cs.CV] 16 Jan 2019 Weighted space.
