Uber plans to deploy 20,000 robotaxis across U.S. and international markets over six years, with rides available exclusively through the Uber app.

Geospatial Knowledge Graphs (GeoKGs) model geoentities (e.g., places and natural features) and spatial relationships in an interconnected manner, providing strong knowledge support for geographic applications, including data retrieval, question-answering, and spatial reasoning. However, existing methods for mining and reasoning from GeoKGs, such as popular knowledge graph embedding (KGE) techniques, lack geographic awareness. This study aims to enhance general-purpose KGE by developing new strategies and integrating geometric features of spatial relations, including topology, direction, and distance, to infuse the embedding process with geographic intuition. The new model is tested on downstream link prediction tasks, and the results show that the inclusion of geometric features, particularly topology and direction, improves prediction accuracy for both geoentities and spatial relations. Our research offers new perspectives for integrating spatial concepts and principles into the GeoKG mining process, providing customized GeoAI solutions for geospatial challenges.

After months of teasers and announcements, Lucid Motors will finally reveal its first all-electric luxury sedan, the Air, during a live stream on September 9. But of course, the day before the big reveal, a little bit of news has trickled out. Lucid Motors has previously alluded that it will offer a high-end variant of the Air. That flagship variant, called the Dream, is expected to cost $169,000 (or $161,500 after federal tax credits are accounted for), according to a report by Bloomberg. The report said Lucid will produce a Grand Touring variant that will be priced in the low $130,000s after federal tax credits, as well as a sub-$100,000 Touring model.
