Unsupervised Scale-consistent Depth and Ego-motion Learning from Monocular Video

Neural Information Processing Systems

Recent work has shown that CNN-based depth and ego-motion estimators can be learned using unlabelled monocular videos. However, the performance is limited by unidentified moving objects that violate the underlying static scene assumption in geometric image reconstruction.





Approximation Ratios of Graph Neural Networks for Combinatorial Problems

Neural Information Processing Systems

To this end, we first establish a new class of GNNs that can solve a strictly wider variety of problems than existing GNNs. Then, we bridge the gap between GNN theory and the theory of distributed local algorithms.
