IA-FaceS: A Bidirectional Method for Semantic Face Editing

1 code implementation24 Mar 2022 Wenjing Huang, Shikui Tu, Lei Xu

To strike a balance between the reconstruction capacity and the control flexibility, the encoder is designed as a multi-head structure to yield embeddings for reconstruction and control, respectively: a high-dimensional tensor with spatial properties for consistent reconstruction and four low-dimensional facial component embeddings for semantic face editing.

Revisit Lmser and its further development based on convolutional layers

no code implementations12 Apr 2019 Wenjing Huang, Shikui Tu, Lei Xu

Proposed in 1991, Least Mean Square Error Reconstruction for self-organizing network, shortly Lmser, was a further development of the traditional auto-encoder (AE) by folding the architecture with respect to the central coding layer and thus leading to the features of symmetric weights and neurons, as well as jointly supervised and unsupervised learning.
