Sequential learning technique for medical image segmentation
Sequential learning techniques, such as auto-context, that apply the output of an intermediate classifier as contextual features for its subsequent classifier have shown impressive performance for semantic segmentation. It is shown that these methods can be interpreted as an approximation technique derived from a Bayesian formulation. To improve the effectiveness of applying this approximation technique, a new sequential learning approach is proposed for semantic segmentation that solves a segmentation problem by breaking it into a series of simplified segmentation problems. Sequentially solving each of the simplified problems along the path leads to a more effective way for solving the original segmentation problem. To achieve this goal, a learning-based method is proposed to generate simplified segmentation problems by explicitly controlling the complexities of the modeling classifiers. Promising results were reported on the 2013 SATA canine leg muscle segmentation dataset. |

On the client device, a counterpart video rendering application can receive the transmitted video data, decode it, and render it in a window that is overlaid onto a corresponding area of the virtual desktop graphical user interface (GUI) in a client application. Headless video composition can be implemented for rendering the video on the client, giving the illusion of the video playing inside the virtual desktop, while it is actually playing on the client itself. |

Write-back storage cache based on fast persistent memory
A storage device uses non-volatile memory devices for caching. The storage device operates in a mode referred to herein as write-back mode. In write-back mode, a storage device responds to a request to write data by persistently writing the data to a cache in a non-volatile memory device and acknowledges to the requestor that the data is written persistently in the storage device. The acknowledgement is sent without necessarily having written the data that was requested to be written to primary storage. Instead, the data is written to primary storage later. |

Backup mechanism of writing sequential data to single-level cell buffer and multi-level cell buffer
A data storage device includes a memory device and a controller. The memory device includes a first buffer, a second buffer, and a backup memory block. The first buffer is an MLC block and the second buffer is an SLC block. The controller is coupled to the memory device, receives a write command to write predetermined data in the memory device and determines whether the predetermined data has to be written into different buffers. When the controller determines that the predetermined data has to be written into different buffers, the controller writes a portion of the predetermined data that has been written in one or more predetermined pages of the first buffer into the backup memory block. |

Automated integration testing with mock microservices
Automated software-testing systems and computer program products use mock software entities to perform integration testing on a microservices-based application. The mock entities emulate the behavior of other microservices or external software applications that would normally interact with the tested microservices in a production environment. The mock entities are managed by a mock server that communicates with the test system through a messaging system. The mock server determines how the mock entities should respond to the tested application's service requests by referring to test guidelines stored in a behavior store. During testing, the test system dynamically updates the behavior store in response to the tested application's service requests and to other indicators of the current state of the tested application. If the tested application interacts with the mock entities during the test as expected, the test system deems the application to have passed the integration test. |

Distributed storage location hinting for non-volatile memories
Examples include methods for obtaining one or more location hints applicable to a range of logical block addresses of a received input/output (I/O) request for a storage subsystem coupled with a host system over a non-volatile memory express over fabric (NVMe-oF) interconnect. The following steps are performed for each logical block address in the I/O request. A most specific location hint of the one or more location hints that matches that logical block address is applied to identify a destination in the storage subsystem for the I/O request. When the most specific location hint is a consistent hash hint, the consistent hash hint is processed. The I/O request is forwarded to the destination and a completion status for the I/O request is returned. When a location hint log page has changed, the location hint log page is processed. When any location hint refers to NVMe-oF qualified names not included in the immediately preceding query by the discovery service, the immediately preceding query is processed again. |

Dynamic de-duplication methodologies for efficient resource utilization on de-duplication system
Embodiments are described for reducing memory usage and disk I/O's for reading and writing streams in a deduplication storage system. Generations of backups of a stream can be tracked for the stream. In the first generation (first backup), stream data is ingested, segmented, and written to disk without looking up a fingerprint of each segment, to save disk I/O's and memory. After the first generation, an amount of stream data processed is tracked, and at dynamically tunable increments of data processed, a fingerprint index lookup is performed to disk. The fingerprint index is read into memory and subsequent fingerprint lookups are preformed to cache, until a next dynamically tunable fingerprint lookup to disk. The dynamically tunable increment of processed data can be randomly reset. |

This probability distribution is computed based on distances (or similarities), in terms of metadata values, between said each unlabeled dataset and the labeled datasets. Based on their associated relevance values, datasets can then be efficiently managed in a storage system. |
