BiGR: Harnessing Binary Latent Codes for Image Generation and Improved Visual Representation Capabilities

ICLR 2025poster

We introduce BiGR, a novel conditional image generation model using compact binary latent codes for generative training, focusing on enhancing both generation and representation capabilities. BiGR is the first conditional generative model that unifies generation and discrimination within the same fr…

Elucidating the design space of language models for image generation

ICML 2025poster

The success of large language models (LLMs) in text generation has inspired their application to image generation. However, existing methods either rely on specialized designs with inductive biases or adopt LLMs without fully exploring their potential in vision tasks. In this work, we systematically…

Referee Can Play: An Alternative Approach to Conditional Generation via Model Inversion

ICML 2024poster

As a dominant force in text-to-image generation tasks, Diffusion Probabilistic Models (DPMs) face a critical challenge in controllability, struggling to adhere strictly to complex, multi-faceted instructions. In this work, we aim to address this alignment challenge for conditional generation tasks.…

Inducing Neural Collapse in Deep Long-tailed Learning

AISTATS 2023poster

Although deep neural networks achieve tremendous success on various classification tasks, the generalization ability drops sheer when training datasets exhibit long-tailed distributions. One of the reasons is that the learned representations (i.e. features) from the imbalanced datasets are less effe…
