  1. Waymos Have Trouble With Floods, Which Is Surprising

    Waymo's autonomous vehicles have encountered significant issues with flooded roads, leading to service disruptions and a recall for a software update. The self-driving cars have driven into floodwaters and become stuck, with one incident involving a vehicle being washed away. This is surprising given Waymo's reliance on LIDAR and detailed mapping, which theoretically should help detect and navigate such hazards, though the company has declined to comment on the specific reasons for these failures.

  5. StruMPL: Multi-task Dense Regression under Disjoint Partial Supervision and MNAR Labels

    Researchers have developed StruMPL, a novel multi-task dense regression model designed to estimate forest aboveground biomass (AGB) using disparate data sources. The model integrates satellite lidar data, which provides structural information but lacks biomass estimates, with ground-based plot data that offers biomass figures but is subject to bias and missingness. StruMPL addresses these challenges by employing a shared encoder with regression, imputation, and propensity heads for spatial correction, alongside a learnable physics module to enforce known allometric laws between variables.
