A Machine Learning Approach for Using the Postmortem Skin Microbiome to Estimate the Postmortem Interval
Hunter Johnson,Donovan D Trinidad,Stephania Guzman,Zenab Khan,James V. Parziale,Jennifer M. DeBruyn,Nathan H. Lents +6 more
TL;DR: A machine learning approach for the use of necrobiome data in the prediction of the postmortem interval (PMI) of microbial samples is outlined, providing a successful proof-of- concept that skin microbiota is a promising tool in forensic death investigations.
Compression Schemes, Stable Definable Families, and o-Minimal Structures
TL;DR: The combinatorial complexity of any definable family in a structure with a o-minimal theory is bounded by the number of parameters in the defining formula, and extended compression schemes for uniformly definable families corresponding to stable formulas are shown to exist.
Some new maximum VC classes
TL;DR: It is shown that Floyd's lemma applies to a wider class of linearly parameterized functions than has been formally recognized to date and, modulo some minor technicalities, the sets of positivity for any linear combination of real analytic functions is maximum on points in general position.

Vapnik-Chervonenkis density on indiscernible sequences, stability, and the maximum property
TL;DR: A maximum set system analogue to Shelah's characterization of stability using indiscernible sequences is given and a way of producing lower bounds on VC_ind-density is given to compute the exact VC-ind- density of polynomial inequalities, and a variety of geometric set families.
