Quantized Conditional COT-GAN for Video Prediction

Causal Optimal Transport (COT) results from imposing a temporal causality constraint on classic optimal transport problems, which naturally generates a new concept of distances between distributions on path spaces. The first application of the COT theory for sequential learning was given in Xu et al. [50], where COTGAN was introduced as an adversarial algorithm to train implicit generative models optimized for producing sequential data. Relying on [50], the contribution of the present paper is twofold. First, we develop a conditional version of COT-GAN suitable for sequence prediction. This means that the dataset is now used in order to learn how a sequence will evolve given the observation of its past evolution. Second, we improve on the convergence results by working with modifications of the empirical measures via a specific type of quantization due to Backhoff et al. [8]. The resulting quantized conditional COT-GAN algorithm is illustrated with an application for video prediction.
