  • Publication number: 20240080116
    Abstract: A method for determining a quantity of passive inter-modulation sources. A quantity of passive inter-modulation sources of a multi-antenna device is obtained. An interference signal that is excited by a sounding signal and that is from a passive inter-modulation source is received. Singular value decomposition is performed on a first matrix corresponding to the interference signal. A quantity of passive inter-modulation sources is determined based on a result of the singular value decomposition. In this way, the quantity of passive inter-modulation sources of the multi-antenna device is directly determined by performing operations including signal receiving and sending and calculation of the multi-antenna device, to implement convenient, accurate, and secure detection of information about the quantity of the passive inter-modulation sources of the multi-antenna device.

  • Patent number: 10579922
    Abstract: The use of the alternating direction method of multipliers (ADMM) algorithm to train a classifier may reduce the amount of classifier training time with little degradation in classifier accuracy. The training involves partitioning the training data for training the classifier into multiple data blocks. The partitions may preserve the joint distribution of input features and an output class of the training data. The training may further include performing an ADMM iteration on the multiple data blocks in an initial order using multiple worker nodes. Subsequently, the training of the classifier is determined to be completed if a stop criterion is satisfied following the ADMM iteration. Otherwise, if the stop criterion is determined to be unsatisfied following the ADMM iteration, one or more additional ADMM iterations may be performed on different orders of the multiple data blocks until the stop criterion is satisfied.
