数据挖掘 9 Graph Embedding
Main problem with graphs: lack of predefined node ordering. Graph is non-Euclidean: the distance among two nodes does not depend on the coordinates of the nodes. Origin idea of graph embedding: graph could become a set of multi-dimensional points in which Euclidean distances represent similarities among the nodes. 2 methods of embedding: Linear embedding: linear transformation of the edges. Random-walk embedding: preserving the probability that a node is reachable from another node. Linear Em ...
Fair Division Conjectures on Price of Fairness for EEFX/MXS
After reading the paper Optimal Bounds on the Price of Fairness for Indivisible Goods to know the notion of Price of Fairness and the paper New Fairness Concepts for Allocating Indivisible Items to adapt new fairness notions EEFX and MXS, it is natural to consider the left open problem: What is the PoF for EEFX and MXS? The Relation between EFX, EEFX, MXS, PROP1 It is not hard to say that EFX⊂EEFX⊂MXS⊂PROP1EFX\sub EEFX\sub MXS\sub PROP1 EFX⊂EEFX⊂MXS⊂PROP1 Every EFX allocation is EEFX allocatio ...
数据挖掘 8 Link Analysis
PageRank as a fundamental tool in graph mining, connections to Markov process and linear algebra. Random Walk PageRank An algorithm that provides a score to each web page. It follows: Each link’s vote is proportional to the importance of its source page. If node jjj with importance rjr_jrj has nnn out links, each of the jjj’s neighbors gets rj/nr_j/nrj/n votes. Page jjj’s own importance is the sum of the votes on its in-links. PageRank can be simply expressed as the sum of the scores of the ...
随机算法 8 Faster Dimensionality Reduction
Lecture notes by Kasper. This lecture: different approaches used to speed up the JL transform. Recall: classic JL transform works by drawing a random matrix AAA with coordinates i.i.d. either N(0,1)\mathcal N(0,1)N(0,1) or uniform random among {−1,+1}\{-1,+1\}{−1,+1} and then embedding a vector xxx to m−1/2Axm^{-1/2}Axm−1/2Ax. m=O(ϵ−2logn)m=O(\epsilon^{-2}\log n)m=O(ϵ−2logn) if one wants to preserve all pairwise distances to within (1±ϵ)(1\pm\epsilon)(1±ϵ) and embedding time is O(dm)O(dm)O(dm). ...
Fair Division 5 Is EF1 Compatible with Pareto-optimality? Introduction to EFX.
Objective: Examine the compatibility of EF1 with Pareto-optimality, introducing the concept of EFX. Activities: Read and present the paper The Unreasonable Fairness of Maximum Nash Welfare. Ioannis et al. ACM Transactions on Economics and Computation 2019 It’s worth to mention that Iannis received Kalai Prize 2024 for this paper 🎆 Hint from Iannis: Ignore appendix, experiments. Focus on the proof, paraphrase it in my own words, a easy way! Maximum Nash welfare (abbr. MNW) selects an allocatio ...

数据挖掘 7 Community Detection
Community detection finds sets of nodes, i.e., that are highly connected inside the community and coarsely connected outside the community. Community: a group of individuals sharing common interests. A community is a subset C⊆VC\subseteq VC⊆V of the nodes VVV. Non-overlapping communities or partitions are pairwise disjoint set Ci,CjC_i,C_jCi,Cj s.t. Ci∩Cj=∅C_i\cap C_j=\emptyCi∩Cj=∅ for each i,ji,ji,j. Overlapping communities are not necessarily pairwise disjoint. Non-overlapping Community D ...
