Abstract: Described herein is a mechanism to adapt a machine learning model used in a language understanding model that has been trained using a first set of user input having a first set of features to effectively operate using user input having a second set of features. Losses are defined based on the first set of features, the second set of features or features common to both the first set and second set. The losses comprise one or more of a source side tagging loss, a reconstruction loss, an adversarial domain classification loss, a non-adversarial domain classification loss, an orthogonality loss, and target side tagging loss. The losses are jointly minimized using a gradient descent method and the resulting coefficients are used to retrain the machine learning model.

Abstract: A computer-implemented technique is described for facilitating the creation of a language understanding (LU) component for use with an application. The technique allows a developer to select a subset of parameters from a larger set of parameters. The subset of parameters pertains to a LU scenario to be handled by the application. The larger set of parameters pertains to a plurality of LU scenarios handled by an already-existing generic LU model. The technique creates a constrained LU component that is based on the subset of parameters in conjunction with the generic LU model. At runtime, the constrained LU component interprets input language items using the generic LU model in a manner that is constrained by the subset of parameters that have been selected, to provide an output result. The technique also allows the developer to create new rules and/or supplemental models.

Abstract: The present disclosure relates to a technique for radio link monitoring in a wireless communication system, and to operation procedures of the base station and user equipment and a method for radio link quality evaluation on the basis of the technique. In the method, the user equipment divides the downlink channel bandwidth into multiple frequency ranges, measures channel states for each frequency range, and evaluates the radio link quality based on channel state measurement results. Thereafter, the user equipment sends frequency range quality information to the base station, which may then utilize the same for downlink resource allocation. Hence, it is possible to solve the problem of the existing scheme wherein the user equipment enters the physical layer problem detection state or the radio link failure state although a frequency range usable for service provisioning is present within the downlink channel bandwidth.
