We propose and show the efficacy of a new method to address generic inverse problems. Inverse modeling is task whereby one seeks determine hidden parameters natural system that produce given set observed measurements. Recent work has shown impressive results using deep learning, but we note there trade-off between model performance computational time. For some applications, time at inference fo...

A Theory-guided Auto-Encoder (TgAE) framework is proposed for surrogate construction and further used uncertainty quantification inverse modeling tasks. The built based on the (or Encoder-Decoder) architecture of convolutional neural network (CNN) via a theory-guided training process. In order to achieve training, governing equations studied problems can be discretized finite difference scheme ...

The ability of global transport models to go up in resolution becomes discriminating for greenhouse gas atmospheric inversions. This paper describes the porting on Graphics Processing Units model currently used European operational Copernicus Atmosphere Monitoring Service (CAMS) CO2 and N2O It represents an important milestone achieve sub-degree resolution. code includes not only direct but als...

Abstract: The legged robot can only walk very similar to human walking pattern. Therefore, many robots have been researched and developed in recent years. However, the biped robots still have many issues for the natural human walking in terms of the redundant degree of freedom, complexity of the kinematics, and stability. In this paper, we have described our biped robot modeling in the forward ...

The lack of a primary method for determination of optical parameters remains a significant barrier in optical study of turbid media. We present a complete system of experimental setups and Monte Carlo modeling tools for fast and accurate solution of the inverse problem from the measured signals of homogeneous turbid samples. The calibration of the instrument and validation of the Monte Carlo mo...

Mathematical modeling and algorithms of direct,and inverse electromagnetic scattering formulation due to biological tissues are investigated. The algorithms are used for a model based illustration technique within the microwave range. A number of methods is given to solve the direct,and inverse electromagnetic scattering problem in which the nonlinear and ill-posed nature of the problem are ack...
