Deep Learning the City : Quantifying Urban Perception At A Global Scale [article]

Abhimanyu Dubey, Nikhil Naik, Devi Parikh, Ramesh Raskar, César A. Hidalgo
2016 arXiv   pre-print
Our results show that crowdsourcing combined with neural networks can produce urban perception data at the global scale.  ...  Using this data, we train a Siamese-like convolutional neural architecture, which learns from a joint classification and ranking loss, to predict human judgments of pairwise image comparisons.  ...  So scaling up the computational methods to map urban appearance from the regional scale, to the global scale, requires methods that can be trained on larger and sparser datasets-which contain a large,  ...

Local2Global: Scaling global representation learning on graphs via local training [article]

Lucas G. S. Jeub, Giovanni Colavizza, Xiaowen Dong, Marya Bazzi, Mihai Cucuringu
2021 arXiv   pre-print
We propose a decentralised "local2global" approach to graph representation learning, that one can a-priori use to scale any embedding technique.  ...  Preliminary results on medium-scale data sets (up to ∼7K nodes and ∼200K edges) are promising, with a graph reconstruction performance for local2global that is comparable to that of globally trained embeddings  ...  Our preliminary results on medium-scale data sets are promising and achieve comparable accuracy on graph reconstruction as globally trained VGAE embeddings.  ...
