Abstract: A combination of two or more trained machine learning models can exhibit a combined accuracy greater than the accuracy of any one of the constituent models. However, this increase accuracy comes at additional computational cost. Cascades of machine learning models are provided herein that result in increased model accuracy and/or reduced model compute cost. These benefits are obtained by conditionally executing one or more of the models of the cascade based on the estimated correctness of already-executed models. The estimated correctness can be obtained as an additional output of the already-executed model(s) or could be determined as an entropy, maximum class probability, maximum class logit, or other function of the output(s) of the already-executed model(s). The expected computational cost of executing the model cascade is reduced by only executing the downstream model(s) when the upstream model(s) has resulted in an output whose accuracy is suspect.

Abstract: The disclosure relates to methodology and apparatus for a non-coherent over-the-air computation (OAC) methodology to calculate the majority vote (MV) reliably in fading channel. The disclosed approach relies on modulating the amplitude of the elements of complementary sequences (CSs) based on the sign of the parameters to be aggregated. Since the disclosed method does not use channel state information at the nodes, it is compatible with time-varying channels. The methodology is useful for an unmanned aerial vehicle (UAV) guided by distributed sensors based on the MV computed with the method. The method improves the computation error rate with a longer sequence length in fading channel while maintaining the peak-to-mean-envelope power ratio of the transmitted orthogonal frequency division multiplexing signals to be less than or equal to 3 dB.
