Abstract: A progressive localization method for text-to-video clip localization. The method comprises: first, respectively extracting features of two modes, namely a video mode and a text mode by using different feature extraction methods; then progressively selecting different step sizes, and learning the correlation between the video and the text in multiple stages; and finally, training a model in an end-to-end manner based on the correlation loss of each stage. Moreover, the fine time granularity stage is fused with information of the coarse time granularity stage by means of a condition feature update module and up-sampling connection, such that different stages are mutually promoted. Different stages can pay attention to clips with different time granularities, and the model can cope with the situation that the length of a target clip is obviously changed based on the interrelation between the stages.

Abstract: A database system that, after receiving the query request, adopts a pre-trained deep learning model to predict probing cardinality corresponding to the query request based on the query vector in the query request, the number of vectors of the query result, and the vector corresponding to the distances between the query vector and the center vector of a plurality of data partitions stored in the storage device. The system then determines the target data partitions according to the probing cardinality, and obtains the query result from the target data partitions. Since the probing cardinality is dynamically determined based on the query request, decreases to both the query efficiency due to a larger setting of the probing cardinality, and the query recall due to a smaller setting of the probing cardinality are avoided, which is beneficial in reducing the average number of target data partitions and improving query efficiency.

Abstract: Embodiments of this application provide a method and an apparatus for determining radio channel multipath information and a related device. A server obtains reference signal received powers of a plurality of downlink beams, and determines a path angle and path strength of a propagation path from an antenna in a power angular spectrum cell indicated by each power angular spectrum cell identity to a grid indicated by each grid identity, based on an association relationship between the reference signal received powers of the plurality of downlink beams and the following: a grid identity, a serving cell identity, and a power angular spectrum cell. The server can determine the radio channel multipath information based on the reference signal received powers of the plurality of downlink beams, instead of depending on map and engineering parameter information. This helps improve accuracy of the radio channel multipath information.

Abstract: In a method an Intelligent Data Conversion (IDC) engine of a dataflow system detects a stage transition of a dataflow application executing on the dataflow system. In response, the IDC engine determines that data among stage data of the application has a first Stage Data Format (SDF).

The IDC engine also determines a second processing unit, of the dataflow system to perform the data conversion and dispatches the second processing unit to perform the data conversion. The dataflow computing system can include a runtime processor and the IDC engine can interact with the runtime processor to detect the stage transition and/or dispatch the first processing unit.
