  • Patent number: 12641148
    Abstract: A system and method of interacting with cloud systems using a first cloud system (“FCS”) and an application programming interface (“API”) that interacts with a second and third cloud system, the method comprising: receiving, by the API, a user instruction associated with a file; accessing, in a database of the FCS, metadata for the file to identify a storage setting of the file; accessing, by the processor and when the storage setting is an infrequent identifier, an infrequent storage of the FCS; accessing, by the processor and when the storage setting is a frequent identifier, the frequent storage of the FCS; monitoring, by the processor, a change to the media in the FCS; and implementing, by the processor, the change to the media in the second and third cloud systems thereby syncing and performing real-time reconciliation across the first, second, and third could systems.

  • Publication number: 20250181617
    Abstract: Generating responses to queries with text extracts from unstructured data using AI models includes (i) extracting text from unstructured data sources to create machine-searchable documents, (ii) replacing PII and PHI with entity types and attributes, (iii) determining text extracts that indicate criteria, (iv) using a small-scale ML model to perform text searches and find conceptually associated text strings, (v) generating a custom context for a large language model (LLM), (vi) prompting the LLM to generate a response, (vii) combining the response with an extractive QA model to obtain relevant text extracts as response basis, and (viii) providing system-generated recommendations for next best actions based on responses that produce the most optimal outcomes in historical input documents for manually selected or automatically recommended resolution paths.

  • Patent number: 10026441
    Abstract: The present disclosure relates to a method and apparatus for processing of multi-dimensional readback signal from magnetic recording or optical, physical data recording so as to reduce/control Inter Symbol Interference (ISI) and noise within acceptable limits. The method is based on Partial Response Maximum Likelihood (PRML) detection and takes care of time varying channel conditions. In an embodiment, the filter coefficients of both the equalizer and the partial response (PR) target are jointly adapted to account for the channel condition for both separable and non-separable targets thus reducing signal detection complexity. In an aspect, the disclosure provides an apparatus that incorporates an adaptation engine along with the equalizer and the PR target that updates filter coefficients of both the equalizer and the PR target following the formulated mathematical equations.
