DPAR: Dynamic Patchification for Efficient Autoregressive Visual Generation

CVPR 2026

Decoder-only autoregressive image generation typically relies on fixed-length tokenization schemes whose token counts grow quadratically with resolution, substantially increasing the computational and memory demands of attention. We present DPAR, a novel decoder-only autoregressive model that dynami

Incorporating functional summary information in Bayesian neural networks using a Dirichlet process likelihood approach

AISTATS 2023poster

Bayesian neural networks (BNNs) can account for both aleatoric and epistemic uncertainty. However, in BNNs the priors are often specified over the weights which rarely reflects true prior knowledge in large and complex neural network architectures. We present a simple approach to incorporate prior k…
