Abstract: Power-combining devices, and more particularly spatial power-combining devices with increased output power are disclosed. Increased output power may be realized by increasing a number of transmission paths for amplification that are associated with each amplifier assembly of a spatial power-combining device. Each transmission path may include an input antenna structure, an amplifier, and an output antenna structure for providing amplification of signals that pass therethrough. In this manner, a total number of transmission paths for amplification may be increased without having to increase a total number of amplifier assemblies. Further improvements to electrical separation and stability between neighboring amplifier assemblies may be provided by electrically grounded conductive sheets that are arranged between neighboring amplifier assemblies.

Abstract: Gradient Boosting Decision Tree (GBDT) successively stacks many decision trees which at each step try to fix the residual errors from the previous steps. The final score produced by the GBDT is the sum of the individual scores obtained by the decision trees for an input vector. Overfitting in GBDT can be reduced by removing the input values that have the least impact on the output from the training data. One way to determine which input variable has the lowest predictive value is to determine the input variable that is used for the first time in the latest decision tree in the GBDT. This method of identifying the low-predictive features to be removed does not require that earlier trees be regenerated to generate the new GBDT. Since the removed feature was already not used in the earlier trees, those trees already ignore the removed feature.

It further includes inserting the metrics data point into the determined time series. It further includes updating a metadata catalog based at least in part on the metrics data point.

Abstract: A transmitter/receiver (1) up-converts, using an LO signal as a local oscillation signal, an IF signal having a predetermined frequency band, thereby generating a transmission signal RFTX. Moreover, the transmitter/receiver (1) generates a (LO+IF)2 signal and a (LO?IF)2 signal based on the IF signal and the LO signal. Using the LO signal obtained by adding-up of the (LO+IF)2 signal and the (LO?IF)2 signal, a reception signal RFRX is down-converted. Thus, a local oscillation signal generation unit of a receiving unit is not necessary.
