A new research paper explores using autoencoder latent feature representations to detect bus delays and service anomalies in Niterói. The study found that while the autoencoder's latent representation did not significantly improve delay detection compared to traditional methods, it did provide a stable day-level anomaly signal. However, the effectiveness of this signal was limited by the alarm threshold, and the delay model relied heavily on a single feature, with no individual latent dimensions proving interpretable. AI
