Abstract: An acoustic respiratory monitoring system (105) detects, monitors, and/or tracks acoustic features of respiratory conditions for a human patient. Acoustic respiratory data is derived from breathing sound captured by a sensor array (410) comprising a plurality of acoustic sensor elements (412). A plurality of logical channels is determined based on the acoustic respiratory data. An adventitious feature is detected in the breathing sound using the plurality of logical channels, and an indication of an abnormal respiratory sound is provided via a user interface (800), in response to detecting the adventitious feature. The sensor array (410) may be integrated with a wearable article (560), such as a shirt, vest, or belt, for example.

Abstract: Artificial intelligence (AI) techniques for connection networking are described. A method comprises receiving an input vector by a multi-tower machine learning (ML) model for a content delivery system of a connection network system, generating a set of user embeddings from a first vector of the input vector by a first tower of the multi-tower ML model based on the activity data associated with users of the connection network system, generating a set of campaign embeddings from a second vector of the input vector by a second tower of the multi-tower ML model based on the textual description of the content delivery campaign, generate a metric based on a subset of the user embeddings and a subset of the campaign embeddings, selecting audience user identifiers based on the metric, and sending content items for the content delivery campaign to electronic devices of the audience user identifiers.

Abstract: In an example embodiment, a generator model such as a large language model (LLM) is leveraged to generate embeddings for both pieces of content and users. The embeddings map the pieces of content and the users into the same latent n-dimensional space. The embeddings are then fine-tuned using a two-tower deep neural network, with one of the towers representing users and the other tower representing content. The two-tower deep neural network is trained to optimize the embeddings over some shared goal, such as user engagement with content, and uses information such as user interactions with content in that process. A clustering technique, such as K-nearest neighbor (kNN) can then be used to identify a grouping of top user/content pairs based on similarity between users and content, as reflected in the embeddings. For a given piece of content, therefore, the top users from that cluster can then be recommended as an audience for the content.
