摘要： Embodiments of the disclosure provide a method for configuring indication devices in transportation services. The method includes receiving a plurality of transportation requests including passenger pick-up points located in a preset geographical area. The method further includes identifying a first transportation request matching a first vehicle and a second transportation request matching a second vehicle, where the first vehicle and the second vehicle are detected to be located in the preset geographical area. The method also includes determining that first indication information assigned with the first transportation request shares an attribute with second indication information assigned with the second transportation request. The method additionally includes adjusting the first indication information so that the first indication information no longer shares the attribute with the second indication information.

摘要： Embodiments of the disclosure provide systems and methods for audio signal processing. An exemplary system may include a communication interface configured to receiving a first audio signal acquired from an audio source through a first channel, and a second audio signal acquired from the same audio source through a second channel. The system may also include at least one processor coupled to the communication interface. The at least one processor may be configured to determine channel features based on the first audio signal and the second audio signal individually and determine a cross-channel feature based on the first audio signal and the second audio signal collectively. The at least one processor may further be configured to concatenate the channel features and the cross-channel feature and estimate spectral-spatial masks for the first channel and the second channel using the concatenated channel features and the cross-channel feature. The at least one processor may also be configured to perform beamforming based on the spectral-spatial masks for the first channel and the second channel.

摘要： The present disclosure includes artificial intelligence systems and methods for identifying grids for a geofence in an area in a map that includes a plurality of independently indexed regions of grids. The map is gridded into a plurality of grids and divided into a plurality of partitions. The methods include obtaining information of the geofence in the map, and determining a boundary grid series of the geofence from the plurality of grids. The methods include identifying at least one enclosed area in the geographical region, and upon determining that an enclosed area crosses two or more partitions, segmenting the enclosed area into two or more sub-areas. The methods also include determining boundary grids for each sub-area, and identifying internal grids in the sub-area for each sub-area. The methods further include identifying grids in the geographical region by collecting the boundary grids and the internal grids.
