Scraping jobs are defined in YAML configuration files rather than imperative scripts, supporting pagination, rate limiting, headless Chrome rendering, and failure recovery out of the box.</p> <p>The goal is a tool that makes structured data collection from the web reliable and repeatable without requiring users to write and maintain brittle scraping code.</p> <p><strong>Collaborators:</strong> Dhyanna Patel, Santosh Iragvarapu</p> 2025-08-01T00:00:00+00:00 2025-08-01T00:00:00+00:00 Unknown https://arpeggio.group/projects/bounceback/ <p><strong>BounceBack</strong> is a community-centric decentralized disaster recovery logistics services platform, conceived by Noah Guzinski after volunteering in tornado recovery efforts in the summer of 2025.</p> <p>The core insight: in the immediate aftermath of a disaster, centralized coordination often lags behind the speed at which communities self-organize. BounceBack explores how local-first approaches — where data and decision-making live at the edge, close to the people doing the work — can support more effective grassroots disaster response.</p> <p>The project sits at the intersection of several Arpeggio AWARE research areas: distributed systems engineering, cloud-native resilience, and the social dynamics of how communities coordinate under stress.</p> <p><strong>Collaborators:</strong> Noah Guzinski, Jack Crane, Samuel Kann, Mathew Shereni, Ngan Nguyen</p> 2025-05-15T00:00:00+00:00 2025-05-15T00:00:00+00:00 Unknown https://arpeggio.group/projects/eye-in-the-sky/ <p>Fall 2024–Spring 2025.

This Spring 2025 Sigma Xi project explores how data-driven insights can identify a skater's ideal conditions for executing spins, jumps, and full programs. Using CatBoostRegressor and SHAP (SHapley Additive exPlanations), the study analyzes individual training factors to produce actionable, personalized recommendations for each skater.</p> <p><strong>Collaborator:</strong> Elizabeth Wangley</p> 2024-12-15T00:00:00+00:00 2024-12-15T00:00:00+00:00 Unknown https://arpeggio.group/projects/legal-semiotics/ <p>Legal Semiotics: A Focus on the Intersectionality between Technology and Intellectual Property.
