Dear workshop community,
We will convene for the Applied Statistics Workshop (Gov 3009) tomorrow on
Wednesday (11/28).
The speaker is* Tracy Ke *(Harvard Stats) who will be presenting her work
"Statistical Analysis of Large Social Networks".
<http://www.mattblackwell.org/files/papers/telescope_matching.pdf>
*Where:* CGIS Knafel Building, Room K354 (see this link
<https://map.harvard.edu/?bld=04471&level=9> for directions).
*When: *Wednesday, November 28th --- 12 noon - 1:30 pm.
*Abstract:* Severe degree heterogeneity is a universal phenomenon in large
social networks. However, the degree parameters are largely nuisance to our
major interest, and their effects can be carefully removed with proper
statistical strategies. In the first part of the talk, I will take the
mixed-membership estimation as an example and present several useful ideas
for dealing with degree heterogeneity. We assume the network has K
perceivable communities. Each node is associated with a K-dimensional
“membership” vector whose entries describe the nodes’ “weights” on
different communities. The goal is to estimate these membership vectors. We
adopt a degree-corrected mixed-membership model and propose a spectral
method that is conceptually simple, computationally fast, and rate-optimal.
*¶* In the second part, I will showcase a dataset we have collected about
coauthor/citation networks of statisticians. The data set consists of the
meta information (e.g., authors, abstracts, citation counts, etc.) of about
70,000 papers in 36 representative journals in statistics and related
fields, from 1984-2015. The dataset provides a fertile ground for
methodological comparisons and for scientific discoveries. We report some
Exploratory Data Analysis (EDA) results, such as productivity,
journal-journal citation exchanges, and citation patterns of individual
papers.
*All are welcome! Lunch is provided! *
Best,
