Variational Autoencoded Regression:
High Dimensional Regression of Visual Data on Complex Manifold
Abstract
This paper proposes a new high dimensional regression
method by merging Gaussian process regression into a variational autoencoder framework. In contrast to other regression methods, the proposed method focuses on the case
where output responses are on a complex high dimensional
manifold, such as images. Our contributions are summarized as follows: (i) A new regression method estimating
high dimensional image responses, which is not handled by
existing regression algorithms, is proposed. (ii) The proposed regression method introduces a strategy to learn the
latent space as well as the encoder and decoder so that the
result of the regressed response in the latent space coincide
with the corresponding response in the data space. (iii) The
proposed regression is embedded into a generative model,
and the whole procedure is developed by the variational autoencoder framework. We demonstrate the robustness and
effectiveness of our method through a number of experiments on various visual data regression problems.
