Reviews: Beyond Vector Spaces: Compact Data Representation as Differentiable Weighted Graphs

Neural Information Processing Systems 

Except the presence of each edge is probabilistic than deterministic, the core idea is quite similar to Isomap. The novelty should be better addressed by comparing to Isomap. For example, edges between words that frequently co-occur in the same contexts are not independent to each other. Edges between pixels in small coherent regions are not independent. Do we eventually need to know such dependency structures a priori to correctly represent arbitrary geometry in the data?
