Towards Scalable Backpropagation-Free Gradient Estimation
A new study on arXiv discusses the limitations of backpropagation in deep learning, particularly its requirement for two passes through neural networks and the storage of intermediate activations. The research highlights the challenges faced by existing gradient estimation methods that utilize forward-mode automatic differentiation, which often struggle to scale effectively due to high variance in estimates. This work is significant as it seeks to address these issues, potentially paving the way for more efficient training methods in machine learning.
