Heterogeneous Relational Kernel Learning [article]

Andre T. Nguyen, Edward Raff
2019 arXiv   pre-print
Recent work has developed Bayesian methods for the automatic statistical analysis and description of single time series as well as of homogeneous sets of time series data.  ...  We extend prior work to create an interpretable kernel embedding for heterogeneous time series.  ...  A time series is modeled by a Gaussian process model and the goal is to find a descriptive and expressive kernel.  ...

2011 International Journal on Applied Bio-Engineering  
We evaluate time series data from microarray experiments.  ...  Time series microarray data analysis provides an invaluable insight into the genetic progression of metastasis. In this paper we analyzed time series microarray data of cancer metastasis.  ...  We use a different distance measures that mainly take the shape of the time series into account and to construct clusters that can be explained by a given set of features.  ...

Toward More Honest Description1

Jennifer Douglas
2016 The American Archivist  
I conclude by arguing for a more honest description of archives, one that acknowledges the various ways in which archives are shaped over time, even when these ways conflict with traditional archival thinking  ...  It suggests that archivists need to more carefully consider three types of archives shaping: shaping by the archiving I; shaping by other interested parties; and shaping by the archivist.  ...  I focus on three different types of archival shaping-shaping by the creator of the archives, shaping by the archivist, and shaping by other interested parties.  ...
