February is off to a busy start for the CHAMPS. On Tuesday, January 30th, 2024, the team delivered their Qualification Review Board (QRB) presentation to a committee of coaches including Dr. Rong Zhang, Dr. Jorg Peters, and Dr. Catia Silva. The presentation discussed the project overview and progress as well as risks and mitigation strategies. Based on the feedback, the CHAMPS performed well with only a few adjustments to make to their ongoing plan. Dr. Silva explained that the team lacks a model output evaluation method and recommended that the CHAMPS utilize synthetic data to measure accuracy. The team has since discussed this issue with Verifone on Thursday and the liaisons are actively working to provide data for testing purposes. The QRB review committee also deliberated that the presentation lacked system usage and process details. Consequently, the CHAMPS are addressing these comments for the QRB 2 presentation on February 27th by including system design diagrams, deployment outlines, and the motivation behind each model architecture. During the rest of the week, the team also made progress with dimensionality reduction, researching ensemble methods, and implementing the isolation forest. The CHAMPS will continue working on these tasks into the next week with hopeful results of increased model efficiency.
