Pre-Warm: Input-Conditioned Weight Initialization for Convolutional Neural Networks

arXiv:2606.25256v1 Announce Type: cross Abstract: We introduce Pre-Warm, a simple yet effective zero-training-cost method for data-conditioned initialization of the first convolutional layer. Before the first forward pass, Pre-Warm extracts mean-centered local patches from a single training batch, clusters them with MiniBatchKMeans, applies inverse Manhattan spatial weighting, and uses the resulting centroids to initialize half of the first-layer filters (the remainder retain Kaiming initialization). We derive closed-form rules for all hyperparameters except a single insensitive scale paramete

Why this matters
Why now

The continuous push for more efficient and performant AI models drives innovation in foundational techniques like initialization.

Why it’s important

Improved initialization methods, especially zero-training-cost ones, can significantly reduce the computational burden and time required to train advanced convolutional neural networks.

What changes

This method offers a potentially more efficient way to initialize the first layer of CNNs, leading to faster convergence and better performance without additional training overhead.
