HIGH DIMENSIONAL SURROGATE MODELING FOR LEARNING UNCERTAINTY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240135185 titled 'HIGH DIMENSIONAL SURROGATE MODELING FOR LEARNING UNCERTAINTY
Simplified Explanation
The method described in the patent application involves using a variational autoencoder (VAE) to learn a low-dimensional latent space representation of high-dimensional data, and then using a polynomial chaos expansion to map new data samples in the latent space to the corresponding data output. This allows for estimation with high-dimensional datasets under uncertainty, such as missing values, by estimating the values using the set of distributions learned by the VAE.
- Variational autoencoder (VAE) used to learn a low-dimensional latent space representation of high-dimensional data
- Encoder part of the VAE outputs a set of distributions of the high-dimensional dataset in a latent space
- New data samples are sampled in the latent space using the set of distributions from the encoder
- Polynomial chaos expansion is used to map the new data samples in the latent space to the corresponding data output
- Estimation with high-dimensional datasets under uncertainty, such as missing values, is performed using the set of distributions learned by the VAE

Original Abstract Submitted
a method to determine data uncertainty is provided. the method receives a high dimensional data input and a corresponding data output. the method trains a variational autoencoder (vae) with the high dimensional data input to learn a low dimensional latent space representation of the high dimensional data input. an encoder part of the vae outputs a set of distributions of the high dimensional dataset in a latent space. the method samples new data samples in the latent space using the set of distributions outputs from the encoder part of the vae. the method learns a polynomial chaos expansion to map the new data samples in the latent space to the corresponding data output to learn the set of distributions and their relation to perform estimation with high-dimensional dataset under uncertainty such as missing values by estimating the values using the set of distributions.
