Decoder-only Clustering in Attributed Graphs
Yik Lun Kei, Oscar Hernan Madrid Padilla, Rebecca Killick +3
This manuscript studies nodal clustering in graphs having multivariate attributes at each node. The framework includes node-specific priors for low-dimensional representations, cou…
Genetic Algorithms in Regression
Mo Li, QiQi Lu, Robert Lund +1
Many statistical problems involve optimization over a discrete parameter space having an unknown dimension. In such settings, gradient-based methods often fail due to the non-diffe…
The Asymptotic Distribution for a Single Joinpoint Changepoint Model
Xueheng Shi, Robert Lund
A single joinpoint changepoint model partitions a time series into two segments, joined at the changepoint time by constraining the estimated piecewise linear regression responses…
Single Changepoint Procedures
Robert Lund, Xueheng Shi
Single changepoint tests have become a staple check for homogeneity of a climate time series, suggesting how climate has changed should non-homogeneity be declared. This paper summ…
