UnsupervisedGraphNeuralArchitectureSearch withDisentangledSelf-supervision

Neural Information Processing Systems

The existing graph neural architecture search (GNAS) methods heavily rely on supervised labels during the search process, failing to handle ubiquitous scenarios where supervisions are not available. In this paper, we study the problem of unsupervised graph neural architecture search, which remains unexplored inthe literature. The key problem is to discover the latent graph factors that drive the formation of graph data as well as the underlying relations between the factors andtheoptimal neural architectures.





Consensus Learning with Deep Sets for Essential Matrix Estimation

Neural Information Processing Systems

Robust estimation of the essential matrix, which encodes the relative position and orientation of two cameras, is a fundamental step in structure from motion pipelines. Recent deep-based methods achieved accurate estimation by using complex network architectures that involve graphs, attention layers, and hard pruning steps.






Successor-Predecessor Intrinsic Exploration Changmin Y u 1,2 Neil Burgess

Neural Information Processing Systems

Exploration is essential in reinforcement learning, particularly in environments where external rewards are sparse. Here we focus on exploration with intrinsic rewards, where the agent transiently augments the external rewards with self-generated intrinsic rewards.
