arXiv:2607.08406v1 Announce Type: new Abstract: Backpropagation (BP) dominates deep learning training, but its reliance on gradients brings inherent troubles -- vanishing and exploding gradients. The pursuit of gradient-free methods has long been a goal in the field of artificial intelligence. This paper shows that indeed the simplest Monte Carlo algorithm implemented on a single GPU -- randomly mutate a parameter, keep it if the loss decreases, otherwise retry -- can practically train deep networks. This gradient-free method does not even need common techniques such as batch normalization or
The deep learning field continues to seek more efficient and less computationally demanding training methods, pushing research towards alternatives to the dominant backpropagation algorithm.
This research suggests a potential paradigm shift in how neural networks are trained, potentially democratizing advanced AI development by reducing dependence on complex and resource-intensive gradient-based methods.
The fundamental reliance on backpropagation for neural network training may be challenged, opening avenues for simpler, gradient-free approaches to become practical for deep learning.

A practical gradient-free training method could significantly lower the barrier to entry for developing complex deep learning models.
Reduced computational complexity might accelerate AI innovation by allowing for faster iteration and exploration of novel network architectures.
This could lead to a decentralization of AI development, as the need for massive, specialized compute clusters for training is diminished, potentially impacting the compute supply chain dynamic.
