Exact inference under the perfect phylogeny model
Surjyendu Ray, Bei Jia, Sam Safavi +4
Motivation: Many inference tools use the Perfect Phylogeny Model (PPM) to learn trees from noisy variant allele frequency (VAF) data. Learning in this setting is hard, and existing…

Efficient Projection onto the Perfect Phylogeny Model
Bei Jia, Surjyendu Ray, Sam Safavi +1
Several algorithms build on the perfect phylogeny model to infer evolutionary trees. This problem is particularly hard when evolutionary trees are inferred from the fraction of gen…

On the Complexity of the Weighted Fused Lasso
Jose Bento, Ralph Furmaniak, Surjyendu Ray
The solution path of the 1D fused lasso for an -dimensional input is piecewise linear with segments (Hoefling et al. 2010 and Tibshirani et al 2011). However, e…
