Abstract: Disclosed herein are training strategies for query-based object detectors, referred to herein as Query Recollection (QR). In one variation or QR, dense query recollection, every intermediate query is collected and independently forwarded to every downstream stage. In a second variation or QR, selective query recollection, intermediate queries are collected from the two nearest previous stages and forwarded to the next downstream stage. This eliminates the phenomena wherein intermediate stages of the decoder produce more accurate results than later stages of the decoder.

Abstract: Disclosed methods respond to detecting the receipt, by a management controller, such as a baseboard management controller (BMC), of an information handling system, of a provisioning request from a management client, by rebooting the information handling system to initiate a Universal Extensible Firmware Interface (UEFI) boot sequence that is configured to load an EFI application, referred to herein a provisioning application. A two way communication channel such as a WebSocket is established between the management client and the management controller to stream OS image data corresponding to an OS image to the management controller. The OS image data streamed to the management controller is written to an OS image partition of a boot device, after which the stored OS image may be booted to load the OS. The provisioning request may be communicated as a representational state transfer (REST) compliant (RESTful) request using, in at least some deployments, a Redfish application programming interface (API).
