The present invention relates to improvements to systems and methods for determining a current location of a client device, and for identifying and selecting appropriate geo-fences based on the current location of the client device. An improved geo-fence selection system performs operations that include associating media content with a geo-fence that encompasses a portion of a geographic region, sampling location data from a client device, defining a boundary based on the sampled location data from the client device, detecting an overlap between the boundary and the geo-fence, retrieving the media content associated with the geo-fence, and loading the media content at a memory location of the client device, in response to detecting the overlap.

A vision transformer network having extremely low latency and usable on mobile devices, such as smart eyewear devices and other augmented reality (AR) and virtual reality (VR) devices. The transformer network processes an input image, and the network includes a convolution stem configured to patch embed the image. A first stack of stages including at least two stages of 4-Dimension (4D) metablocks (MBs) (MB) follow the convolution stem. A second stack of stages including at least two stages of 3-Dimension MBs (MB) follow the MBstages. Each of the MBstages and each of the MBstages include different layer configurations, and each of the MBstages and each of the MBstages include a token mixer. The MBstages each additionally include a multi-head self attention (MHSA) processing block.

Systems, devices, media, and methods are presented for selectively partitioning and precaching data elements. The systems and methods identify a device context for a client device and identify a cell based on the device context. The cell is associated with one or more partition characteristics and a plurality of data elements stored in a precache of data elements. The systems and methods select a set of data elements corresponding to the cell and at least a portion of the one or more partition characteristics. The systems and methods then retrieve the selected set of data elements from the precache of data elements and cause presentation of at least one data element of the selected set of data elements at a display device coupled to the client device.
