  • Patent number: 10764150
    Abstract: A system, method, and computer program product are provided for preparing multi-feed of log data in an AI-managed communication system. In use, log data of a communication network is obtained and a plurality of artificial intelligence (AI) models are obtained. The log data is analyzed with a first AI model of the plurality of AI models to detect at least one occurrence of a respective classifier. A first confidence level for the first AI model is computed. A reduced log data feed is formed by eliminating at least one parameter from the log data. Further, a second confidence level for the first AI model is calculated by repeating the analysis of the log data, the computation of the first confidence level, and the formation of the reduced log data feed until at least one: the second confidence level is lower than the first confidence level, or the second confidence level reaches a threshold.

    Abstract: Systems and methods include initializing a trainees population (TP), calculating an objective function (OF) of the TP to identify a trainer. A teaching pool is created using variables of each trainee and the identified trainer, and unique variables are added to obtain an updated teaching pool (UTP). Search is performed on the UTP to obtain ‘m’ subset of variables and OFs. The OFs of ‘m’ subset are compared with OFs of the trainer's and each trainee's variable and one of the trainer or each trainee are updated accordingly. An updated learning pool (ULP) is created for selected trainee and the trainees, by adding unique variables to obtain ‘n’ subset. The OF of ‘n’ subset are compared with objective functions of selected trainee and the trainees and variables are updated accordingly. These steps are iteratively performed to obtain an optimal subset of variables that is selected for teaching and learning phase.

In a linear system, the correction parameter converges to a constant when optimized (evaluated on-line). The new MPC controller and method can also be applied on a nonlinear system. In a non-linear system, where the time constant is non-linear, the correction parameter will be variable.

    Abstract: Methods and systems for controlling a physical system (plant) are disclosed. The plant is modeled as a linear, finite-dimensional system having a state vector, a control input vector, a plant output vector, and a disturbance vector comprising disturbances having known basis functions and unknown amplitudes. An adaptive control law is used with separate adaptive gains for an error vector associated with the plant output vector, and the disturbance vector, plus a fixed gain for a disturbance estimator. The adaptive control law is operable to adjust the control input vector so as to minimize the error vector. The plant includes modes which are not Almost Strictly Positive Real (ASPR).
