Learn low-dim Embeddings that encode GRAPH structure (data) : "Representation Learning" /arXiv

Описание: Optimize your complex Graph Data before applying Neural Network predictions. Automatically learn to encode graph structure into low-dimensional embeddings, using techniques based on deep learning and nonlinear dimensionality reduction.

An encoder-decoder perspective, random walk approaches or Neighborhood aggregation methods/encoders.

Since central problem in machine learning on graphs is finding a way to incorporate information about graph-structure into a machine learning model.

Find a way to represent, or encode, graph structure so that it can be easily exploited by your Machine Learning models.
