This week, Team INSIGHT continued making strides in our Verifone project, collaborating to complete the required QRB documents. These efforts ensured that we were aligned with Verifone’s expectations and prepared for the subsequent phases of development. Each subteam made notable progress, laying a strong foundation for upcoming tasks.

The UI team focused on designing the whole pipeline’s backend architecture, incorporating Verifone’s suggestions. This design work is critical to ensuring a seamless integration of the front and back ends. The Feature Engineering (FE) team implemented z-score calculations for duration and amount using a rolling window, experimenting with different designs to optimize runtime. They also made significant progress in spatial feature engineering, extracting key geographical attributes such as city, state, and zip code. The Machine Learning (ML) team advanced their work on isolation forests, seq2seq models, and Optuna integration, further refining our approach to anomaly detection.

Looking ahead, the subteams have ambitious plans for next week. The UI team will continue Angular development, focusing on map integration and clustering research while finalizing anomaly and statistics scripts for UI implementation. The FE team aims to complete their proposed spatial features and optimize the preprocessing pipeline in collaboration with the ML team. The ML team will work on formatting JSON outputs for backend integration, ensuring that anomaly detection results are effectively communicated.

As we reflect on this week, it’s clear that collaboration and communication remain the keys to our success. We are excited to build on this momentum as we move closer to delivering a polished and impactful solution.
