Huber Loss
The Huber loss function is a robust loss function used in machine learning that combines the strengths of mean squared error (MSE) and mean absolute error (MAE), mitigating the impact of outliers while maintaining sensitivity to smaller errors. Current research focuses on adapting the Huber loss, often through dynamic parameter adjustments or variations like the pseudo-Huber loss, to improve performance in diverse applications such as image generation (diffusion models), time series analysis (nonlinear system parameter estimation), and federated learning. This adaptability makes the Huber loss a valuable tool across various fields, enhancing the robustness and accuracy of models in the presence of noisy or corrupted data. Its impact is seen in improved model performance and more reliable estimations in numerous applications, from 5G network optimization to reinforcement learning.
