VQ-Transplant: Efficient VQ-Module Integration for Pre-trained Visual Tokenizers

ICLR 2026poster

Vector Quantization (VQ) underpins modern discrete visual tokenization. However, training quantization modules for state-of-the-art VQ-based models requires significant computational resources which, in practice, all but prevents the development of novel, cutting-edge VQ techniques under resource co…

Rethinking the Uniformity Metric in Self-Supervised Learning

ICLR 2024poster

Uniformity plays an important role in evaluating learned representations, providing insights into self-supervised learning. In our quest for effective uniformity metrics, we pinpoint four principled properties that such metrics should possess. Namely, an effective uniformity metric should remain inv…

Controlled Text Generation Using Dictionary Prior in Variational Autoencoders

ACL 2022findings

While variational autoencoders (VAEs) have been widely applied in text generation tasks, they are troubled by two challenges: insufficient representation capacity and poor controllability. The former results from the posterior collapse and restrictive assumption, which impede better representation l…
