Abstract: Provided herein are systems and methods for sanitizing logged data packets in a distributed system prior to storing them in a remote or third-party data server. Interactions with an application are monitored and values in a data packet are extracted from the interaction. The values are classified based on a classification configuration and respective labels of the values. The values are then sanitized based on the classification to prevent exposure of secure or private data. The sanitized data packets are then logged into the remote data server. The logged data can be used to help resolve events occurring in the application. The classification configuration can be iteratively updated and the interactions repeated to capture data that was previously sanitized to aid in resolution of events. The logged data can also be used in research or analysis, such as for identifying potential improvements to the application.

Machine classifiers may be used to help users to perform tasks indicated by the user. When a user utterance is received, natural language processing techniques may be used to understand the user's intent. Templates may be determined based on the user's intent in the generation of responses to solicit information from the user. A variety of persona attributes may be determined for a user. The persona attributes may be determined based on the user's utterances and/or provided as metadata included with the user's utterances. A response persona may be used to generate responses to the user's utterances such that the generated responses match a tone appropriate to the task. A response persona may be used to generate templates to solicit additional information and/or generate responses appropriate to the task.

Abstract: A method for determining a wearing state of an earphone. Acceleration data are acquired using an acceleration sensor. A time characteristic of the acceleration data is ascertained, and curve segments are ascertained. The curve segments are each formed by first and second sections. A first wearing state of the earphone is determined, in which the earphone is worn on the ear, if a curve segment including a first section having a positive course and a second section having a negative course is ascertained, and if a first characteristic shape is ascertained for the curve segment. A second wearing state of the earphone is determined, in which the earphone is not worn on the ear, if a curve segment including a first section having a negative course and a second section having a positive course is ascertained, and if a second characteristic shape is ascertained for the curve segment.

Abstract: LiDAR system and methods discussed herein use a dispersion element or optic that has a refraction gradient that causes a light pulse to be redirected to a particular angle based on its wavelength. The dispersion element can be used to control a scanning path for light pulses being projected as part of the LiDAR's field of view. The dispersion element enables redirection of light pulses without requiring the physical movement of a medium such as mirror or other reflective surface, and in effect further enables at least portion of the LiDAR's field of view to be managed through solid state control. The solid state control can be performed by selectively adjusting the wavelength of the light pulses to control their projection along the scanning path.

Abstract: Machine classifiers in accordance with embodiments of the invention capture long-term temporal dependencies in the dialogue data better than the existing RNN-based architectures. Additionally, machine classifiers may model the joint distribution of the context and response as opposed to the conditional distribution of the response given the context as employed in sequence-to-sequence frameworks.

The random padding of the input data may further provide regularization during the training of the machine classifier and/or reduce exposure bias. In a variety of embodiments, the input data may be encoded based on subword tokenization.
