- MILADeep Learning | Visiting ResearcherRESEARCHMay 2019 - February 2020 (9 months)Montreal, CanadaDeep Learning Research | Mila, Montreal, CanadaDuring my year at Mila, I had the opportunity to collaborate with a world-class team of deep learning researchers under the guidance of Turing Laureate Yoshua Bengio. My primary focus was on the "This Climate Does Not Exist" project, an innovative generative AI-driven tool designed to raise awareness about the impacts of climate change.Technical ContributionsAs part of this interdisciplinary team, I played a key role in implementing state-of-the-art Generative Adversarial Networks (GANs) to develop a Flooding Simulator. This involved extending the GAN architecture to generate realistic visualizations of climate-related disasters, such as floods and wildfires, by analyzing and transforming Google Street View images. Through this work, I gained extensive experience in deep learning, computer vision, and neural network architecture.Impact and RecognitionOur project successfully bridged the gap between AI and climate science, harnessing machine learning to incite action. The tool received recognition at the NeurIPS Workshop and Montreal AI Symposium, showcasing its potential to use technology for social good.LearningsThis experience honed my skills in advanced machine learning techniques, collaboration in a multidisciplinary environment, and effectively communicating complex technical concepts.Published work:
- Developed ClimateGAN, a deep learning model for visualizing extreme climate events, which was presented at ICLR 2022. ClimateGAN, is a model that leverages both simulated and real data for unsupervised domain adaptation and conditional image generation. https://openreview.net/forum?id=EZNOb_uNpJk - DOI: 10.48550/arXiv.2110.02871 Simulator available online: https://thisclimatedoesnotexist.com/
