Abstract: A data transmission method includes: A transmit end obtains indication information used to indicate that a first compressed packet is lost or fails to be decompressed. The transmit end sends a target original packet or a target compressed packet. The target compressed packet is generated by compressing the target original packet based on a preset compression parameter. The target original packet includes at least one of the following packets: a first original packet corresponding to the first compressed packet, and a second original packet corresponding to a second compressed packet compressed after the first compressed packet. The technical solution provided in this application can improve transmission efficiency that exists when a compressed packet is lost or fails to be decompressed.

Abstract: A preliminary software feature is applied in a testing rollout to a discrete subset of customers. Survey data may be collected from those customers through a variety of sources, such as chatbot text, session workflow, historical user data, social media data, email survey data, user profile data, messaging threads, and the like. This survey data is analyzed using machine learning algorithms to derive the meaning of input text as well as to determine the user sentiment expressed therein. The outputs of this analysis are normalized across sources and aggregated at a feature-level to generate overall metrics of customer satisfaction with the feature. A holistic analysis is performed on this customer sentiment data to obtain an aggregate or combined user satisfaction score. This score is applied against a set of guardrails to determine whether to ship the feature to a broader customer base.

Abstract: A computing device receives a message including a request for a recommendation. A representation of a hypothetical ideal recommendation to provide in response to the message is determined based on the message content. Data regarding entities that are potential recommendations are retrieved from a data store, the data regarding each entity including a representation of the entity (e.g., a vector) derived from factual information about the entity and opinions of other users of the entity. Ranking scores are determined for at least a subset of the entities based on the difference between the entity representations and the representation of the hypothetical ideal recommendation. An entity to recommend is selected based on the ranking scores and a reply to the message is sent that identifies the selected entity.

Abstract: Methods and devices are provided for optically interrogating subsurface tissues of a body. Optical interrogation includes illumination of a target tissue through an external body surface and detection of light emitted in response to the illumination. Parameters of such optical interrogation are controlled according to operational modes that are selected to maximize detector sensitivity to a target property of the target subsurface tissues. Operational modes are selected based on detected properties of the target tissue and of intervening tissues (e.g., thickness of intervening tissues between the target tissue and an external body surface) between the target tissue and an interrogating optical device. Operational modes can be determined based on simulated optical interrogation of subsurface tissue across a range of optical detector configurations and tissue conditions. Operational modes can include calibration curves specifying optical interrogation parameters based on intervening tissue properties.
