IDInit is a novel initialization method for neural networks that maintains identity transitions within layers, enhancing convergence, stability, and performance during training. By employing a padded identity-like matrix and addressing issues like dead neurons, IDInit offers a straightforward yet effective approach applicable to various deep learning models and large-scale datasets.

Efficient backpropagation (BP) is a fundamental technique in deep learning, first introduced by Seppo Linnainmaa in 1970, building on earlier concepts by Henry J. Kelley in 1960 and others. Despite its origins, BP faced skepticism for decades before gaining acceptance as a viable training method for deep neural networks, which can now efficiently optimize complex models. The article highlights the historical development of BP and addresses misconceptions surrounding its invention and application in neural networks.
