New frameworks offer gradient-free and hierarchical learning for stable deep network training

Two new research papers propose alternative methods for training deep neural networks. One paper introduces a projection-based framework called PJAX, which treats training as a feasibility problem solvable through iterative projections, offering a gradient-free and parallelizable approach. The other paper presents Self-Abstraction Learning (SAL), a hierarchical method where simpler networks guide the training of more complex ones sequentially, aiming to improve stability and overcome issues like gradient vanishing.
