	Multi-Camera Smartphone Image Identification Source camera identification uses small imperfections in a camera’s sensor array, called a camera fingerprint. We introduce the new CSAFE multi-camera smartphone image database and discuss how we adapt traditional camera identification methods to work on multi-camera smartphones. This webinar is scheduled for Tuesday, September 26, at 11:00 a.m. CT.
	Cognitive Bias in Forensic Analyses What does it mean when someone talks about human factors considerations or cognitive bias concerns in forensic science and what recommendations exist to address these concerns? This webinar will be followed by a group activity in which attendees will work through the simple implementation of a new framework to address concerns raised in the webinar. This 90-minute webinar/workshop is scheduled for Tuesday, October 24, at 11:00 a.m. CT.
	Intentional Language in Forensic DNA Testimony & Reporting This webinar is a practical training tool for criminal justice training partners and DNA analysts who intend to provide clear and accurate descriptions of DNA results in forensic testimony and reports. This event will include real-life examples of good reporting practices and poor testimony practices from transcripts with immediate tips on how to avoid making common mistakes. This webinar is on-demand and available immediately.
	Visual Diagnostics for Algorithmic Cartridge Case Comparisons Automatic cartridge case comparison algorithms can be used to measure the similarity between two fired cartridge cases. However, many of these algorithms are difficult to interpret, understand, and audit. We introduce a suite of visual diagnostic tools that are useful for understanding the behavior of automatic comparison algorithms and introduce a novel algorithm that returns a probability that two cartridge cases originated from the same firearm. This webinar is on-demand and available immediately.
	Creating a Forensic Database of Footwear Impressions from Retail Tread Photos Shoe tread impressions are one of the most common types of evidence left at crime scenes. The seminar will describe the development and evaluation of computer vision-based techniques for automatically matching class characteristics of crime scene evidence to a large-scale database of commercial footwear tread photos. This webinar is on-demand and available immediately.
	Algorithms for Forensic Science Learn more about the key components of the use of and barriers to implementation of algorithms in forensic science. This learning opportunity is on-demand and available immediately.
	Combining Kinematic and Visual Data to Implement Various Twin Convolutional Neural Networks to Classify Writers This research poster was presented at the American Academy of Forensic Sciences annual conference in 2023. An interactive poster is available for your viewing.
	Error Rate Testing Learn more about what makes a good validation study and what makes a good error rate study. This learning opportunity is on-demand and available immediately.
	A Likelihood Ratio Approach for Detecting Behavioral Changes in Device Usage Over Time This research poster was presented at the American Academy of Forensic Sciences annual conference in 2023. An interactive poster is available for your viewing.
	Introduction to R Stats Starter This beginner level Stats Starter introduces learners to R - a programming language often used to navigate statistics -and its application to forensic evidence. This learning opportunity is on-demand and available immediately.
