Anomaly Detection in Bitcoin Network Using Unsupervised Learning Methods
Thai Pham,Steven F. Lee +1 more
TL;DR: Three unsupervised learning methods including k-means clustering, Mahalanobis distance, and Unsupervised Support Vector Machine are used on two graphs generated by the Bitcoin transaction network to detect which users and transactions are the most suspicious.
Journal ArticleDOI
Estimating Average Treatment Effects: Supplementary Analyses and Remaining Challenges
TL;DR: In this article, the authors extend lessons from the earlier literature to this new setting and propose that in addition to reporting point estimates and standard errors, researchers report results from a number of supplementary analyses to assist in assessing the credibility of their estimates.

Anomaly Detection in the Bitcoin System - A Network Perspective
Thai Pham,Steven F. Lee +1 more
TL;DR: The goal is to detect which users and transactions are the most suspicious; in this case, anomalous behavior is a proxy for suspicious behavior in the Bitcoin transaction network.
