Conditional COT-GAN for Video Prediction with Kernel Smoothing

Tianlin Xu, Beatrice Acciaio

Causal Optimal Transport (COT) results from imposing a temporal causality constraint on classic optimal transport problems, which naturally generates a new concept of distances bet…

Generative modeling of spatio-temporal weather patterns with extreme event conditioning

Konstantin Klemmer, Sudipan Saha, Matthias Kahl +2

Deep generative models are increasingly used to gain insights in the geospatial data domain, e.g., for climate data. However, most existing approaches work with temporal snapshots…

COT-GAN: Generating Sequential Data via Causal Optimal Transport

Tianlin Xu, Li K. Wenliang, Michael Munn +1

We introduce COT-GAN, an adversarial algorithm to train implicit generative models optimized for producing sequential data. The loss function of this algorithm is formulated using…

Variational f-divergence Minimization

Mingtian Zhang, Thomas Bird, Raza Habib +2

Probabilistic models are often trained by maximum likelihood, which corresponds to minimizing a specific f-divergence between the model and data distribution. In light of recent su…
