Abstract: Systems, apparatuses, and methods for training a machine learning (ML) model. Training the ML model may include using contour lines on a plot of prediction values to expected values to determine loss values indicative of errors between prediction values output by the ML model and corresponding expected values. The contour lines may be associated with loss values. Using the contour lines to determine the loss values may include, for each prediction value-expected value pair: generating a one-dimensional loss function through the prediction value-expected value pair, and using the one-dimensional loss function to determine a loss value for the prediction value-expected value pair. Training the ML model may include using an overall loss function to determine an overall loss of the ML model based on the determined loss values. Training the ML model may include adjusting the ML model to minimize the overall loss of the ML model.

Abstract: Systems, apparatuses, and methods for training and/or assessing the stability of a machine learning (ML) model. Training and/or assessing the stability may include, for each input sample n of N input samples, for each perturbation q of Q perturbations: determining a perturbed input sample nq by perturbing the input sample n and using the ML model to obtain a perturbed output yqn based on the perturbed input sample nq. Training and/or assessing the stability may include, for each input sample n of the N input samples, aggregating the perturbed outputs yqn to obtain an aggregate perturbed output yn of the Q perturbations for the input sample n. Training the ML model may include updating one or more parameters of the ML model based on at least the aggregate perturbed outputs yn. Assessing the stability may include aggregating the aggregate perturbed outputs yn (or relative output variations ynrel).

Abstract: A charging circuit for a capacitor in a defibrillator includes a control enabling a setting of a desired time to charge a capacitor to a desired voltage in the defibrillator. The charging circuit further includes a flyback charge-pump circuit comprising a switch, an energy transfer transformer, an energy storage capacitor and a control. The switch is configured to stop or allow storage of energy in a transformer. The transformer transfers the energy to the capacitor. The flyback charge-pump circuit controls a duty-cycle on the switch so that a current draw from a power source (e.g. battery) is sufficient to enable charging the capacitor to the desired voltage within the desired time set on the control.

Abstract: Systems and methods for flexible and extensible contact center routing are disclosed. Incoming communications are received at a contact center from one or more customers. A pairing score is determined for each agent capable of servicing the incoming communications for each of the one or more customers based on customer attributes and/or agent attributes that are adjustable and extensible. An incoming communication is routed from a customer to an agent having a highest pairing score with the customer. The incoming communication can be routed on a first communication channel and then switched over to a second communication channel. The first communication channel and second communication channel can be different types of communication channels.

Abstract: A method and related system provide for data tracking and generation for workforce management. The system has a database and tracks customers and conversations customers have with agents. The system tracks contact items each having a contact type and a channel. The system tracks work sessions each having one or more work bursts, based on tracking conversations and contact items. The system provides access to the database for users, reports or workforce management systems.

Abstract: A computer system may receive a layout of a data center, the layout of the data center identifying physical locations of a plurality of server racks, electrical distribution feeds, and uninterruptible power supplies. The computer system may receive a fault domain configuration for the datacenter, the fault domain configuration identifying virtual locations of a plurality of logical fault domains for distributing one or more instances so that the instances are stored on independent physical hardware devices within a single availability fault domain. The computer system may determine the configuration for the data center by assigning the plurality of fault domains to a plurality of electrical zones, wherein each electrical zone provides a redundant electrical power supply across the plurality of logical fault domains in an event of a failure of one or more electrical distribution feeds. The computer system may display the configuration for the data center on a display.

Abstract: Systems and methods are discussed herein for an optimal approach for wireless emergency alerting within cells of wireless communication networks by using a careful estimation of a “true effective radius” of each cell/sector to eliminate broadcasts falling short of alert area boundaries (with users in such gaps in coverage not receiving an alert despite being in the designated alert area). By utilizing true provisioning information of each cell/sector that is at least partly within the alert area boundaries to understand the true effective radii of particular cell sectors can be selected for broadcast of the alert such that the entire alert area is covered for broadcasting of the alert without excessive over-broadcasting, e.g., broadcasting excessively beyond the alert area boundaries. Alerts can then be broadcast within each selected cell sector.
