PCA-VAE: Differentiable Subspace Quantization without Codebook Collapse

Hao Lu, Onur C. Koyun, Yongxin Guo +3

Vector-quantized autoencoders deliver high-fidelity latents but suffer inherent flaws: the quantizer is non-differentiable, requires straight-through hacks, and is prone to collaps…

Beyond Stationarity: Rethinking Codebook Collapse in Vector Quantization

Hao Lu, Onur C. Koyun, Yongxin Guo +3

Vector Quantization (VQ) underpins many modern generative frameworks such as VQ-VAE, VQ-GAN, and latent diffusion models. Yet, it suffers from the persistent problem of codebook co…
