An Intermediate Fusion ViT Enables Efficient Text-Image Alignment in Diffusion Models

no code implementations25 Mar 2024 Zizhao Hu, Shaochong Jia, Mohammad Rostami

Diffusion models have been widely used for conditional data cross-modal generation tasks such as text-to-image and text-to-video.

Text-to-Image Generation

Efficient Multimodal Diffusion Models Using Joint Data Infilling with Partially Shared U-Net

no code implementations28 Nov 2023 Zizhao Hu, Shaochong Jia, Mohammad Rostami

Recently, diffusion models have been used successfully to fit distributions for cross-modal data translation and multimodal data generation.

Cognitively Inspired Cross-Modal Data Generation Using Diffusion Models

no code implementations28 May 2023 Zizhao Hu, Mohammad Rostami

Most existing cross-modal generative methods based on diffusion models use guidance to provide control over the latent space to enable conditional generation across different modalities.

Encoding Binary Concepts in the Latent Space of Generative Models for Enhancing Data Representation

1 code implementation22 Mar 2023 Zizhao Hu, Mohammad Rostami

We propose a novel binarized regularization to facilitate learning of binary concepts to improve the quality of data generation in autoencoders.

Continual Learning Disentanglement

GalilAI: Out-of-Task Distribution Detection using Causal Active Experimentation for Safe Transfer RL

no code implementations29 Oct 2021 Sumedh A Sontakke, Stephen Iota, Zizhao Hu, Arash Mehrjou, Laurent Itti, Bernhard Schölkopf

Extending the successes in supervised learning methods to the reinforcement learning (RL) setting, however, is difficult due to the data generating process - RL agents actively query their environment for data, and the data are a function of the policy followed by the agent.
