Human-Centric Video Generation via Collaborative Multi-Modal Conditioning

AAAI 2026technical

Human-Centric Video Generation (HCVG) methods seek to synthesize human videos from multimodal inputs, including text, images, and audio. Existing methods struggle to effectively coordinate these heterogeneous modalities due to two challenges: the scarcity of modality-complete data and the difficulty

Phantom-Data: Towards a General Subject-Consistent Video Generation Dataset

ICLR 2026poster

Subject-to-video generation has witnessed substantial progress in recent years. However, existing models still face significant challenges in faithfully following textual instructions. This limitation, commonly known as the copy-paste problem, arises from the widely used in-pair training paradigm. T…

A4A: Adapter for Adapter Transfer via All-for-All Mapping for Cross-Architecture Models

CVPR 2025poster

Large-scale text-to-image models evolve rapidly in size and architecture. The existing adapters struggle to keep pace with these models, requiring extensive retraining. This paper proposes a novel adapter transfer framework, A4A (Adapter for Adapter), which uses an all-for-all mapping approach to se…

CustomContrast: A Multilevel Contrastive Perspective for Subject-Driven Text-to-Image Customization

AAAI 2025technical

Subject-driven text-to-image (T2I) customization has drawn significant interest in academia and industry. This task enables pre-trained models to generate novel images based on unique subjects. Existing studies adopt a self-reconstructive perspective, focusing on capturing all details of a single im…

Phantom: Subject-Consistent Video Generation via Cross-Modal Alignment

ICCV 2025poster

The continuous development of foundational models for video generation is evolving into various applications, with subject-consistent video generation still in the exploratory stage. We refer to this as Subject-to-Video, which extracts subject elements from reference images and generates subject-con…

An Effective Deployment of Diffusion LM for Data Augmentation in Low-Resource Sentiment Classification

EMNLP 2024main

Sentiment classification (SC) often suffers from low-resource challenges such as domain-specific contexts, imbalanced label distributions, and few-shot scenarios. The potential of the diffusion language model (LM) for textual data augmentation (DA) remains unexplored, moreover, textual DA methods st…

DreamIdentity: Enhanced Editability for Efficient Face-Identity Preserved Image Generation

AAAI 2024technical

While large-scale pre-trained text-to-image models can synthesize diverse and high-quality human-centric images, an intractable problem is how to preserve the face identity and follow the text prompts simultaneously for conditioned input face images and texts. Despite existing encoder-based methods…

Enhancing Hindi Feature Representation through Fusion of Dual-Script Word Embeddings

COLING 2024main

Pretrained language models excel in various natural language processing tasks but often neglect the integration of different scripts within a language, constraining their ability to capture richer semantic information, such as in Hindi. In this work, we present a dual-script enhanced feature represe…

PuLID: Pure and Lightning ID Customization via Contrastive Alignment

NeurIPS 2024poster

We propose Pure and Lightning ID customization (PuLID), a novel tuning-free ID customization method for text-to-image generation. By incorporating a Lightning T2I branch with a standard diffusion one, PuLID introduces both contrastive alignment loss and accurate ID loss, minimizing disruption to the…

Towards Accurate Image Coding: Improved Autoregressive Image Generation With Dynamic Vector Quantization

CVPR 2023highlight

Existing vector quantization (VQ) based autoregressive models follow a two-stage generation paradigm that first learns a codebook to encode images as discrete codes, and then completes generation based on the learned codebook. However, they encode fixed-size image regions into fixed-length codes and…
