Title: Explainable Forensic Evaluation for Trace Evidence Executive Summary Introduction: Statement of the Problem - Brittleness Motivation NIJ report statement (no consistent method) Example: Pics of iris data set before and after using cliff Contributions Propose cliff to augment current models to reduce brittleness Propose knn+cliff as forensic model Results from knn+cliff are easy to explain to a jury Cliff runs in linear time Related Work Forensic evaluation of trace evidence with univariate data (glass) Forensic evaluation of trace evidence with multivariate data (glass + spectra) Statistical and Bayesian Methods CLIFF Design and Implementation Idea behind cliff: *to increase speed and reduce brittleness of evaluation - reduce instance space to only the best instances which represent each class *to have a measure of how reliable results are Bore algorithm for ranking attribute values Instance selection algorithm Implications for criminal justice policy and practice in the United States. Measure of the reliability of forensic evaluation and speed can help guide the direction of an investigation Evaluation $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Main body.
