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 ...
随机算法 7 Dimensionality Reduction
Lecturer: Iannis Goal of dimensionality reduction: represent a high dimensional data set in a lower dimensional space while preserving much of the important structure. PCA (principle component analysis): to maintain as much variance in the data as possible while reducing the dimensionality. The mapping of data from a high dimensional space to a low dimensional space is called an embedding. Johnson-Lindenstrauss Dimensionality Reduction Lecture notes by Allan Grønlund Main results of JL: any mmm ...
Fair Division 4 Alternatives to EFX
Objective: Investigate alternative fairness concepts for allocating indivisible items. Activities: Read and present the paper New Fairness Concepts for Allocating Indivisible Items by Ioannis et al. IJCAI2023 🍬Bonus: Methodology After reading some papers in fair division with indivisible items. I have come up with a naive 👓 methodology about research in this field.

数据挖掘 6 Spectral Theory and Clustering
This module introduces graph mining. Data points from networks, graphs, of connections. Purpose: extract patterns from graphs. 3 different areas of graph mining: Community detection: finding groups of nodes with similar characteristics. Link analysis: understanding which node is more important than others. Embedding: capturing similarities among nodes. Graph G=(V,E)G=(V,E)G=(V,E): a set of vertices VVV connected through edges E⊆V×VE\subseteq V\times VE⊆V×V. undirected & directed graph Grap ...
随机算法 6 Streaming Heavy Hitters
Lecture notes by Kasper. Review of Count Sketch This course: extends the results for count sketch algorithm (Lecture 5). Strict turnstile model, where we maintain estimates of some underlying frequency vector fff. The vector fff has coordinates indexed by integers in [U][U][U] for some universe size UUU. We receive updates one at a time. An update: (i,Δ)(i,\Delta)(i,Δ) and has the effect of updating fi←fi+Δf_i\gets f_i+\Deltafi←fi+Δ for i∈[U]i\in[U]i∈[U] and Δ∈{x}x=−MM\Delta\in\{x\}_{x=-M}^MΔ ...
Fair Division 3 Price of Fairness and MMS Property
Objective: Explore the concept of the Price of Fairness and Maximin Share (MMS) property. Activities: Read and present paper Optimal Bounds on the Price of Fairness for Indivisible Goods (2020) and Approximation Algorithms for Maximin Fair Division (2020). Paper on PoF Price of Fairness measures the worst-case loss of social welfare due to fairness constraints. This paper: Both EF1 and 12{1\over2}21-MMS guarantees has PoF O(n)O(\sqrt n)O(n), where nnn is number of agents. For 12{1\over2}21- ...
