Could you build this?
No Training a 500-layer neural network without gradient descent or skip connections requires novel fundamental machine learning research and non-standard mathematical optimization algorithms.
What it would actually take: A real implementation requires novel research into alternative optimization methods (such as forward-forward algorithms, target propagation, or synthetic gradients) combined with custom CUDA/PyTorch kernels to manage numerical stability across 500 unconstrained layers. This demands specialized theoretical ML expertise and extensive empirical hyperparameter exploration.
