Abstract: An approach is described for a method, product, and apparatus for a machine learning process using weight sharing within a systolic array having reduced memory bandwidth. According to some embodiments, this approach includes providing a systolic array that includes processing elements which each have some number of storage elements for storing weights. For example, the weights can be reused for different data sets by identifying/capturing a current state of the storage elements, generating a plan to transition to a target state of those storage elements, and application of the transition plan such that weights that are already stored in those storage elements can be reused and/or relocate. This lowers the bandwidth requirements for weight memory by allowing weights that have previously been read into the systolic array to be reused.

Abstract: Systems and methods may facilitate initial establishment and/or handover of an air-to-ground (ATG) communication link between an aircraft and a ground-based cellular communication network (e.g., a 5G network). The systems and methods may be particularly applicable for an aircraft having a user equipment (UE) antenna that uses narrow beamforming to connect to a cell of a base station (gNB). The UE identifies candidate cells based upon the location of the UE and locations and orientations of cells in the network, identifies a cell having a higher likelihood of connection success compare to other cells, and directs a beam to the chosen cell. The systems and methods may enable the UE to create neighbor lists in real time based upon the UE location, and may prevent blind searching normally associated with narrow beamforming methods.
