Forward-only CNNs achieve new state-of-the-art with learnable channel assignment

Researchers have developed a new forward-only learning algorithm for convolutional neural networks (CNNs) that improves upon existing methods. This approach introduces a learnable mechanism for assigning channels to classes, allowing for more adaptive and data-driven specialization. Additionally, a loss-aware layer contribution strategy weights intermediate predictions based on their validation performance, enhancing inference. When integrated into residual CNNs, this method achieves state-of-the-art performance among forward-only models on several image datasets, significantly closing the gap with traditional backpropagation techniques.

    Forward-Only Convolutional Neural Networks with Learnable Channel-Class Assignment

    arXiv:2606.09928v1 Announce Type: cross Abstract: The Forward-Forward (FF) algorithm offers a biologically inspired alternative to backpropagation by replacing gradient-based credit assignment with local, forward-only objectives. While recent extensions have adapted FF to convolu…
