The present invention discloses a method for fine-tuning the boundaries of hand-woven cashmere images based on weakly supervised learning and multi-stage segmentation. First, a coarse-grained trimap map is obtained through a basic weakly supervised teacher-student network, and a cashmere dense alpha map, edge area and sparse area are obtained through segmentation. Then, the cashmere edge area is expanded using a global cold loss and local ant loss algorithm to obtain the expanded edge area, and the expanded area is input into a collaborative parallel multi-resolution convolutional network for fine cashmere edge segmentation. A lightweight triple loss network is used to segment the sparse area to obtain a coarse-grained cashmere sparse area alpha map. Finally, through continuity judgment, a fine cashmere sparse area alpha map is synthesized, and the three alpha maps are combined for batch normalization and splicing to output the final overall alpha map. This method can effectively improve the accuracy of cashmere area segmentation, especially the robustness of fine-grained and edge processing, solves the problem that the length of existing hand-woven cashmere can only be detected manually, and reduces the annotation cost of pixel-level images.

Methods are disclosed for UE handling of arrangements of AI / ML related measurements and data collected but not yet transferred to the network in case of termination or loss of network connection. This can include mobility operations (e.g., handover); RRC state transitions; radio link failure; or change of PSCell. From configuration information received from a source network node specifying measurement and data collection for AI / ML model training, the UE handles the AI / ML data according to one of several procedures. The UE can delete it; send it to a target RAN node (with which the UE reestablishes network connection); continue performing AI / ML measurements; indicate to the target RAN node availability of previously collected data; or indicate to the target RAN node whether the source node configured AI / ML measurement configuration.
