It explains the need for graph sparsification and provides a concrete example using medical data. The post also delves into the details of using PMI to assess the relevance of edges in the graph and remove irrelevant edges. It concludes with caveats and potential improvements when using PMI for graph sparsification. ## Full article daily.dev links to this article rather than hosting it.
