BGDB: Bernoulli-Gaussian Decision Block with Improved Denoising Diffusion Probabilistic Models

AAAI 2025technical

Generative models can enhance discriminative classifiers by constructing complex feature spaces, thereby improving performance on intricate datasets. Conventional methods typically augment datasets with more detailed feature representations or increase dimensionality to make nonlinear data linearly…

Beyond Skip Connection: Pooling and Unpooling Design for Elimination Singularities

AAAI 2025technical

Training deep Convolutional Neural Networks (CNNs) presents unique challenges, including the pervasive issue of elimination singularities—consistent deactivation of nodes leading to degenerate manifolds within the loss landscape. These singularities impede efficient learning by disrupting feature pr…
