摘要： Systems, apparatuses, methods, and computer-readable media, are provided for distributed machine learning (ML) training using heterogeneous compute nodes in a heterogeneous computing environment, where the heterogeneous compute nodes are connected to a master node via respective wireless links. ML computations are performed by individual heterogeneous compute nodes on respective training datasets, and a master combines the outputs of the ML computations obtained from individual heterogeneous compute nodes. The ML computations are balanced across the heterogeneous compute nodes based on knowledge of network conditions and operational constraints experienced by the heterogeneous compute nodes. Other embodiments may be described and/or claimed.

摘要： A system and method that may facilitate transmission bandwidth savings in non-stationary vehicle-to-vehicle wireless communication channels. At a transmitting vehicle, a transmitter may adaptively change the number of pilot symbols or pilot rate within a frame based upon the current channel statistics. The transmitter may utilize a look-up table approach to select a best pilot rate based upon current conditions associated with the transmitting vehicle, and/or a new frame structure to transmit pilot rate information. At the receiving vehicle, the receiver may be configured to detect a unique waveform transmitted by the transmitting vehicle to estimate the pilot rate information. Alternatively, the receiver on the receiving vehicle may be configured to predict and verify the pilot rate information from an encoded data symbol embedded within a frame transmitted by the transmitting vehicle, which may entail a detection algorithm using encoded data symbols and/or an estimation algorithm using channel statistics.

摘要： An apparatus and an associated method selects rates at which received signals are sampled in a multi-user communication system. The signals are sampled at initial sampling rates during a first period. An estimate is made of the number of received signals, and selection is made of an updated sampling rate, based in part upon the estimate.
