Ensemble of Score Likelihood Ratios under the common source problem
Type: Presentation Slides Research Area(s): Forensic Statistics
Published: 2023 | By: Frederico Veneri
Machine learning-based Score Likelihood Ratios have been proposed as an alternative to traditional Likelihood Ratios and Bayes Factor to quantify the value of evidence when contrasting two opposing propositions. Under the common source problem, the opposing proposition relates to the…

Source Camera Identification on Multi-Camera Phones
Type: Presentation Slides Research Area(s): Digital,Forensic Statistics
Published: 2023 | By: Stephanie Reinders
Camera identification addresses the scenario where an investigator has a questioned digital image from an unknown camera. The investigator wants to know whether the questioned image was taken by a camera on a person of interest’s phone. Researchers discovered that…
Twin Convolutional Neural Networks to Classify Writers Using Handwriting Data
Type: Poster Research Area(s): Forensic Statistics,Handwriting
Published: 2023 | By: Pilhyun (Andrew) Lim
Identifying the source of handwriting is an important application in the field of forensic science that addresses questioned document evidence found in criminal cases and civil litigation. It is difficult, given the idiosyncrasies of a person’s handwriting, to recognize the…
Quantifying Bayes Factors for Forensic Handwriting Evidence
Type: Poster Research Area(s): Forensic Statistics,Handwriting
Published: 2023 | By: Anyesha Ray
Questioned Document Examiners (QDEs) are tasked with analyzing handwriting evidence to make source (or writership) determinations. The Center for Statistics and Applications of Forensic Evidence (CSAFE) has previously developed computational methods to automatically extract quantifiable handwriting features and statistical methods…
Quantifying Writer Variance Through Rainbow Triangle Graph Decomposition of the Common Word “the”
Type: Poster Research Area(s): Forensic Statistics,Handwriting
Published: 2023 | By: Alexandria Arabio
Handwriting comparative analysis is based on the principle that no two individuals can produce the same writing and that an individual cannot exactly reproduce his/her handwriting. This project aims to assess and quantify the natural variations produced by a distinct…
A Likelihood Ratio Approach for Detecting Behavioral Changes in Device Usage Over Time
Type: Poster Research Area(s): Digital
Published: 2023 | By: Rachel Longjohn
This work focuses on the situation in which investigators have obtained as evidence logs of user-generated activities on a device, such as sending text messages or emails, opening or interacting with mobile apps, or making calls from particular locations. Quantitative…
