  • Patent number: 12775627
    Abstract: The present disclosure relates generally to systems and methods for executing a search query using a combination of single-vector searching and multi-vector comparing to more efficiently and accurately identify a set of documents that are responsive to the search query. This involves applying a vector generation model to a search query to generate both single-vector and multi-vector embeddings for the search query. A single-vector search is performed to determine a candidate set of documents that might be relevant to the search query. A more robust multi-vector comparison is then performed to generate a result set including a re-ranked set of documents and/or a further reduced set of documents that is responsive to the search query.

  • Publication number: 20260320663
    Abstract: A system, for example, an online system uses a machine learning based language model, for example, a large language model (LLM) to process crowd-sourced information provided by users. The crowd-sourced information may include comments from users represented as unstructured text. The system further receives queries from users and answers the queries based on the crowd-sourced information collected by the system. The system generates a prompt for input to a machine-learned language model based on the query. The system provides the prompt to the machine-learned language model for execution and receives a response from the machine-learned language model. The response comprises the insight on the topic and evidence for the insight. The evidence identifies one or more comments used to obtain the insight.

  • Publication number: 20260311061
    Abstract: Disclosed is a method for constructing a machine learning model for recommending an airway opening posture angle. The method includes collecting independent variable data affecting a glottis exposure effect when opening a patient airway, conducting an airway opening experiment, taking a posture angle corresponding to an optimal glottis exposure image as an optimal posture angle, performing single-factor analysis on the independent variables, and screening out statistically significant independent variable data as candidate prediction variables. The method further includes preselecting machine learning models, training and verifying the models, evaluating using AUC values, and selecting a model with a highest AUC value as a prediction model for recommending the optimal airway opening posture angle.

  • Patent number: 12602361
    Abstract: An online system uses benchmarking tests to identify indexing algorithms for an embedding database. To perform these benchmarking tests, the online system receives a set of parameters for configuring an embedding database. For example, the parameters may include a performance parameter and a latency parameter. The online system generates algorithm scores for a set of candidate indexing algorithms based on the parameters. Specifically, the online system tests each of the candidate indexing algorithms by generating a testing database based on a subset of the entries for the full database and by performing benchmarking tests on the testing database. The online system uses these tests to compute performance metrics for each candidate indexing algorithm and uses those performance metrics to compute an algorithm score for each indexing algorithm. The online system uses the computed algorithm scores to select an indexing algorithm for the embedding database.

  • Publication number: 20260090686
    Abstract: A vacuum cleaning system comprising a vacuum cleaner having a vacuum motor, a dirt bin, a primary separation system, a membrane filter, and an air valve arrangement configured to control air flow through at least the membrane filter. The vacuum cleaner is configured to be operable in a surface cleaning mode of operation and a self-cleaning mode of operation. In the surface cleaning mode of operation, the vacuum cleaner is configured such that the vacuum motor draws dirty air from a dirty-air inlet through the dirt bin, the primary separation system and the membrane filter in a first airflow direction, and, in the self-cleaning mode of operation, the vacuum cleaner is configured to permit air to flow from the air valve arrangement through the membrane filter in a second airflow direction to clean dirt from the membrane filter. Usefully, therefore, airflow can be routed through the vacuum cleaner in a second or ‘reverse’ direction to clean the caked on dirt from the membrane filter.

  • Publication number: 20250285055
    Abstract: An online system receives a description of a task and generates a prompt for a generative machine-learned model. The prompt includes the description of the task and a request for a sequence of actions associated with the task, and a list of candidate actions and attributes related to the list of candidate actions. The online system provides the prompt to a model serving system deployed with the machine-learning model for execution. The online system obtains a response from the model serving system to extract wherein at least one workflow including the sequence of actions once executed completes a portion of the task. The online system receives, as output from the machine-learned model, the sequence of actions associated with the description of the task. The sequence of actions is executed in order to complete at least a portion of the task.

  • Patent number: 12363605
    Abstract: This disclosure provides systems, methods and apparatuses for a high priority route selection descriptor (RSD) selection timer. A protocol data unit (PDU) session may be established for an application associated with a user equipment (UE). If the PDU session is associated with a lower RSD priority than the highest RSD priority for the application, the UE may initiate an RSD selection timer. After expiration of the RSD selection timer, the UE may try to establish another PDU session for the application with the highest RSD priority for the application. If another PDU session with the highest RSD priority is accepted, the UE may release the initial PDU session with the lower RSD priority and establish a new PDU session with the highest RSD priority. Such implementations may increase data rates, quality of service, and reliability for the application, decrease latency of the application, or decrease power consumption of the UE.
