In this work, we validate experimentally thatconstellation lossoutperforms other metrics for class embedding tasks resulting in higher class classification performance and better cluster separability metrics such as Silhouete[19]and Davis-Boulding index.[20]We also remove the need of using specific suppo...

As evaluation metrics we considertrue positives,false negatives, andrecallmetrics,because we are interested to measure how well the model predicts frauds. In fact using accuracy, in this case, would not be a proper choice: a “model” that always predictsfalse(that is, no fraud) would get m...
In this work, we investigate a wide variety of loss spectral functions for a recurrent neural network architecture suitable to operate in online frame-by-frame processing. We relate magnitude-only with phase-aware losses, ratios, correlation metrics, and compressed metrics. Our results reveal that ...
Loss function plays a key role in successful DML frame- works and a large variety of loss functions have been pro- posed in the literature. Contrastive loss [2, 6] captures the relationship between pairwise data points, i.e., similarity or dissimilarity. Triplet-based losses are also widely...
The contribution of many deep metric learning al- gorithms, such as [26, 22, 5, 2, 3], is the design of a loss function that can learn more discriminant features. Since neural networks are usually trained using the stochastic gradient descent (SGD) in mini-batches, these loss functions ...
In machine learning, loss functions help models determine how wrong it is and improve itself based on that wrongness. They are mathematical functions that quantify the difference between predicted and actual values in a machine learning model, but this isn’t all they do. ...
Search before asking I have searched the YOLOv8 issues and discussions and found no similar questions. Question Hello, I've gone through the discussions regarding loss functions (#4219 and #4025). However, I still have some questions abo...
