The paper introduces CoNN-AL, a framework that combines stream-based active learning with a Cooperative Neural Network and Denoising Autoencoder to efficiently perform partial inverse design in engineering. By estimating predictive uncertainty with Monte Carlo dropout, the method selectively labels the most informative samples in real time, dramatically reducing the number of required simulations. Applied to an automotive glass run channel dataset of over 900,000 designs, CoNN-AL achieves R-squared values between 0.967 and 0.982 using only 2.3% of the full training set, outperforming random sampling and approaching the performance of models trained on much larger datasets.

The paper introduces GCNO, a physics‑based, variable‑rate neural operator that compresses wireless channel matrices by identifying a sample‑dependent set of dominant propagation paths instead of treating the matrix as an image. GCNO leverages receive‑transmit channel structure, a first‑order Taylor correction, and least‑squares recovery to encode path directions and strengths, and the base station reconstructs the channel analytically from these tuples. Experiments on three ray‑traced environments show GCNO outperforms neural feedback baselines in reconstruction accuracy for the same payload or achieves the same accuracy with lower payload, and it generalizes to unseen antenna counts without retraining.
