Researchers and developers in the tr affic domain have also designed and improved DL models for forecasting tas ks such as estimation of traffic speed and time of arrival. However, there exist many challenges in analyzing DL models due to the black-box propert y of DL models and complexity of traffic data (i.e., spatio-temporal depen dencies). Collaborating with domain experts, we design a visual analytics system, AttnAnalyzer, that enables users to explore how DL models make pre dictions by allowing effective spatio-temporal dependency analysis. The sy stem incorporates dynamic time warping (DTW) and Granger causality tests f or computational spatio-temporal dependency analysis while providing map, table, line chart, and pixel views to assist user to perform dependency an d model behavior analysis. For the evaluation, we present three case studi es showing how AttnAnalyzer can effectively explore model behaviors and im prove model performance in two different road networks. We also provide do main expert feedback.\n\nAuthors: Seungmin Jin, Hyunwook Lee, Cheonbok Par k, Hyeshin Chu, Yunwon Tae, Jaegul Choo, Sungahn Ko\n\nRegistration Catego ry: FULL ACCESS, EXPERIENCE PLUS ACCESS, TRADE EXHIBITOR\n\nLanguage: ENGL ISH\n\nFormat: IN-PERSON URL:https://sa2022.siggraph.org/en/full-program/?id=gp_134&sess=sess258 END:VEVENT END:VCALENDAR
