Patent Number: 12223080
This disclosure describes a natural language question (NLQ) query service within a service provider network that provides row level security (RLS) for autocomplete during entry of NLQs and fuzzy matching in NLQ answering. The rules take the form of per-user predicates such as Tim can only see rows with region=US. In configurations a complex extraction and preprocessing pipeline to extract distinct combinations of values against RLS predicate “rule keys” is used. Those distinct values…

Thrashing detection and avoidance for a tiered data processing service

Granted: February 4, 2025
Patent Number: 12216653
Methods for improving performance of tiered storage of a data processing service by detecting and reducing thrashing of data blocks between warm and cold storage tiers are disclosed. In order to understand the frequency of hits by incoming queries to data blocks that are not currently stored in the warm storage tier, the elapsed time between query hits to the respective data blocks may be tracked using timers. Times below a given amount of time may be used to indicate thrashing. For…

Meta-Q learning

Patent Number: 12217137
Techniques for Meta-Q-Learning (MQL) are described. A method of MQL may include receiving a request from an agent to perform adaptation based at least on task data associated with a new task collected by the agent, identifying a subset of meta-training data corresponding to the task data in a replay buffer, and adapting a policy using the subset of meta-training data and the task data to generate an adapted policy, wherein the adapted policy is used identify a next action for the agent…

On-demand co-processing resources for quantum computing

Granted: February 4, 2025
Patent Number: 12217090
An algorithm execution management system of a provider network may receive a request from a user for executing an algorithm using different types of computing resources, including classical computing resources and quantum computing resources. The request may indicate a container that includes the algorithm code and dependencies such as libraries for executing the algorithm. The algorithm execution management system may first determine that the quantum computing resources are available to…

Computer system-based pausing and resuming of natural language conversations

Granted: February 4, 2025
Patent Number: 12216963
Techniques for computer system-based conversations are described. In an example, a system receives, from a first device, first data corresponding to a first interaction in a conversation that requests a function. The system causes the first device to output a first response to the first interaction. Prior to an execution of the function, the system determines that the conversation is to be paused and causes the first device to output a first indication that the conversation is paused.…

Secure monitors for memory page protection

Granted: February 4, 2025
Patent Number: 12216921
Technologies are disclosed for using hardware-embedded monitors to monitor pages of local memory and detect attribute violations or other unauthorized operations relating to the memory. The attribute violations may include mismatches of attributes (e.g., designating a page as writeable versus executable or vice versa) in entries in a translation buffer that point to a same physical address or other mismatches between designations of attributes for a page in physical and virtual space.…

Computer-implemented methods for machine learning model based spatial-temporal adaptive shift for end-to-end text-video retrieval

Granted: February 4, 2025
Patent Number: 12216709
Techniques for performing a machine learning model based spatial-temporal adaptive shift for end-to-end text-video retrieval are described. According to some examples, a computer-implemented method includes receiving a video comprising a plurality of frames at a content delivery service; generating, by the content delivery service, a set of embeddings for each of a plurality of sections of each frame of the plurality of frames; determining, by a candidate selector machine learning model…

Distributed transactions across multiple consensus groups

Granted: February 4, 2025
Patent Number: 12216679
Methods, systems, and computer-readable media for distributed transactions across multiple consensus groups are disclosed. A distributed transaction system comprises a proposer and a plurality of consensus groups, including a first consensus group comprising a first plurality of members and a second consensus group comprising a second plurality of members. The proposer proposes a transaction to at least a portion of the first consensus group and at least a portion of the second consensus…

Enhancing i/o performance using in-memory reservation state caching at block storage services

Granted: February 4, 2025
Patent Number: 12216592
A thread of a storage server determines that a command to modify a reservation record which comprises access permissions of an object stored at the server has been received. A version of the record is stored in an in-memory cache. The thread acquires a first lock associated with the record in exclusive mode, and a second lock in shared mode. The thread reads the cached version, constructs a modified version indicated in the command, and releases the second lock without updating the…
