PHENAKI: VARIABLE LENGTH VIDEO GENERATION FROM OPEN DOMAIN TEXTUAL DESCRIPTIONS
We present Phenaki, a model capable of realistic video synthesis, given a sequence of textual prompts. Generating videos from text is particularly challenging due to the computational cost, limited quantities of high quality text-video data and variable length of videos. To address these issues, we introduce a new mode...

MODE REGULARIZED GENERATIVE ADVERSARIAL NETWORKS
Although Generative Adversarial Networks achieve state-of-the-art results on a variety of generative tasks, they are regarded as highly unstable and prone to miss modes. We argue that these bad behaviors of GANs are due to the very particular functional shape of the trained discriminators in high dimensional spaces, wh...

What Do We Mean by Generalization in Federated Learning?
Federated learning data is drawn from a distribution of distributions: clients are drawn from a meta-distribution, and their data are drawn from local data distributions. Thus generalization studies in federated learning should separate performance gaps from unseen client data (out-of-sample gap) from performance gaps ...

SPREADING VECTORS FOR SIMILARITY SEARCH
Discretizing multi-dimensional data distributions is a fundamental step of modern indexing methods. State-of-the-art techniques learn parameters of quantizers on training data for optimal performance, thus adapting quantizers to the data. In this work, we propose to reverse this paradigm and adapt the data to the quant...

DEEP IMITATIVE MODELS FOR FLEXIBLE INFERENCE, PLANNING, AND CONTROL
Imitation learning provides an appealing framework for autonomous control: in many tasks, demonstrations of preferred behavior can be readily obtained from human experts, removing the need for costly and potentially dangerous online data collection in the real world. However, policies learned with imitation learning ha...

DEEP AUTOAUGMENT
While recent automated data augmentation methods lead to state-of-the-art results, their design spaces and the derived data augmentation strategies still incorporate strong human priors. In this work, instead of fixing a set of hand-picked default augmentations alongside the searched data augmentations, we propose a fu...

Offline Reinforcement Learning with Differentiable Function Approximation is Provably Efficient
Offline reinforcement learning, which aims at optimizing sequential decision-making strategies with historical data, has been extensively applied in real-life applications.

CHURN REDUCTION VIA DISTILLATION
In real-world systems, models are frequently updated as more data becomes available, and in addition to achieving high accuracy, the goal is to also maintain a low difference in predictions compared to the base model (i.e. predictive "churn"). If model retraining results in vastly different behavior, then it could caus...

NEURAL OPTIMAL TRANSPORT WITH GENERAL COST FUNCTIONALS
We introduce a novel neural network-based algorithm to compute optimal transport (OT) plans for general cost functionals.In contrast to common Euclidean costs, i.e., ℓ 1 or ℓ 2 , such functionals provide more flexibility and allow using auxiliary information, such as class labels, to construct the required transport ma...

OUT-OF-DISTRIBUTION DETECTION AND SELECTIVE GENERATION FOR CONDITIONAL LANGUAGE MODELS

Self-training is one of the earliest and simplest semi-supervised methods.
