Lighting Esimation using GANs
For Face lighting estimation, we lack ground truth lighting.
1. Used Spherical Harmonics(SH) to model Lighting
2. Used SIRFS methods to generate noisy SH for Synthetic and Real images.
3. Implemented domain adaption method and implemented LDAN paper
Source code
4. Implemented denoising AutoEncoder to denoise noisy SH and trainined on single neural network which did not perform better than domain adaptation.

Co-Operative GANs
Training GANs is difficult, Generator can face following problems- Mode Collapsing, Saddle point and Local Minima
Updated GANs training procedure as follows to solve these problems-
1. Use multiple Generator with different configuration
2. At the end of each epoch copy weights of best performing Generator to all other Generators
3. Step 2 makes sure we start all-over again and progress towards better resolution
4. Results- Results

ADMM Optimizer in PyTorch
1. Implemented ADDM Optimizer for Lasso solver and Ridge Regression problem
2. Outperformed Scikit-Learn's state of the art Lasso and Ridge solves.
