Abstract: Systems and techniques are described herein for quantizing a codebook used in the context of quantizing post-training parameters (e.g., vectors of weights) of a pre-trained model. For example, a device can perform rank reduction on a tensor of a codebook associated with parameters of a layer of a pre-trained machine learning model to generate a first tensor factor having a first shape and a second tensor factor having a second shape. The device can perform an optimization technique on the first tensor factor and the second tensor factor to minimize an output reconstruction error of the layer. The device can quantize the first tensor factor to generate a reduced size codebook.

Abstract: The systems and methods disclosed herein receives artifacts generated using a first set of models within a multi-model superstructure. The multi-model superstructure includes a second set of models to test the first set of models. The multi-model superstructure dynamically routes the artifacts of the first set of models to one or more models of the second set of models by (i) determining a set of dimensions of the artifacts against which to evaluate the artifacts and (ii) identifying the models in the second set used to test the particular dimension. The second set of models then assesses each artifact against a set of assessment metrics. If an artifact fails to meet one or more assessment metrics, the second set of models generates actions to align the artifact with the set of assessment metrics.

Abstract: A system uses an artificial intelligence (AI) engine to generate a response for end-user devices using services and to provide threat protection in a cloud-based network. The system consists of tenants, tunnels, the AI engine, and an AI reporter. A tenant includes the end-user devices. The tunnels transmit and segregate traffic between the end-user devices and the services. The AI engine intercepts traffic within tunnels, receives a request from a user, and applies functions to manage it. The AI engine monitors the request and generates the response. The AI engine determines patterns based on interactions of the user with services, processes the patterns, generates a baseline of user activity and change settings. The AI engine generates the response based on the settings and sends it to the user to fulfill the request. The AI reporter transmits information corresponding to the request and response across the tenants of the cloud-based network.

Further, the runtime agent may execute one or more actions based on detecting the loading of the one or more software classes by the first computer program where the one or more actions may impact the execution of the first computer program on the virtual machine.

Abstract: A downhole separation system for use upstream of any tool through which a media flows. The separation system filters at least a portion of any solids from the media flowing through a filter flow path. The separation system flushes at least a portion of the filtered solids through a flush flow path, through a flush outlet on an outer surface of a housing, and into a space surrounding the housing. A screen and an activation mechanism are disposed within a housing inner bore. The filter flow path extends through a plurality of openings in the screen. The activation mechanism is configured to move between a default position in which it directs fluid through the filter flow path and an activated position in which it directs fluid through the flush flow path. Optionally, a spring within the housing inner bore is configured to bias the activation mechanism toward the default position.

Abstract: Disclosed embodiments relate to isolation devices for use downhole in a wellbore, for example to isolate a zone of a well. Isolation device embodiments may include a slip, a wedge, a seal element, and a retaining mechanism. The slip may have a run-in position with respect to the wedge and a set position with respect to the wedge. The seal element may be configured to expand radially during movement from the run-in position to the set position. The retaining mechanism may be configured to allow movement of the slip from the run-in position towards the set position, but to lock the slip in the set position. In embodiments, the retaining mechanism may be configured to prevent dislocation of the slip when set, for example forming a retaining cage around the slip.
