Abstract: A method is proposed for machine learning (ML) model alignment. In the method, a first number of samples is generated by a target ML model based on samples selected from a set of samples. A sample comprises a question-answer pair. The set of samples is updated by adding at least a portion of the first number of samples to the set of samples. The target ML model is trained with at least a portion of the updated set of samples. In this way, the ML model self-generalization ability is unlocked to perform alignment with near-zero human supervision.

Abstract: The present disclosure describes hybrid transactional and analytical processing (HTAP) techniques. A HTAP system comprises a first processing engine configured to perform online transactional processing, a second processing engine configured to perform online analytical processing, and a storage in communication with the first processing engine and the second processing engine. The first processing engine, the second processing engine, and the storage may be modularized and configured to be decoupled from each other. The system may be configured to capture data by the first processing engine in real time, organize the data in a first format in a first part of the storage for use by the first processing engine, propagate the data to a second part of the storage subsystem, and organize the data in a second format in the second part of the storage for use by the second processing engine.

Abstract: Embodiments of the present disclosure relate to a method, apparatus, electronic device, and medium for determining fairness impact of a sample on a model. The method comprises generating a counterfactual sample by adjusting an original sample in an original sample set, the original sample set being used for generating an original model for performing a classification task. The method further comprises determining a fairness metric of the original model on a validation sample set. In addition, the method further comprises determining fairness impact of the original sample on the original model based on the fairness metric, the original sample, and the counterfactual sample.

Abstract: A key-value store and a file system are integrated together to provide improved operations. The key-value store can include a log engine, a hash engine, a sorting engine, and a garbage collection manager. The features of the key-value store can be configured to reduce the number of I/O operations involving the file system, thereby improving read efficiency, reducing write latency, and reducing write amplification issues inherent in the combined key-value store and file system.

Abstract: A file system particular for use with key-value stores is provided. The file system can operate in a user space instead of a kernel space. The file system can be an append-only file system. The file system can support use of solid state drives (SSDs) for storage, including zoned SSDs. The file system can include a file manager, a metadata manager, a task scheduler, a space allocator, and a collaborator for collaborating with a key-value store.

Abstract: The present disclosure describes techniques of providing data consistency for hybrid transactional and analytical processing. Logical logs and log serial numbers (LSNs) associated with the logical logs may be generated based on data captured by a first processing engine. The logical logs and the LSNs may be propagated to a storage subsystem configured to be in communication with the first processing engine and a second processing engine. The LSNs and information indicative of LSN schema versions may be stored and distributed by a metadata service. The first processing engine, the second processing engine, the storage subsystem and the metadata service are modularized, and support a LSN mechanism for maintaining data consistency.

Abstract: There are proposed methods, devices, and computer program products for image processing. In the method, a reference dataset is obtained, the reference dataset comprising a plurality of reference samples, a reference sample in the plurality of reference samples comprising: a reference image and a reference label corresponding to the reference image, the reference label indicating a processing result of the image processing. An influence of the reference dataset on a loss is determined, the loss being used for updating an image model associated with the image processing based on the plurality reference samples. A hyperparameter is determined for updating the image model based on the influence of the reference dataset. The image model is updated based on the hyperparameter, the loss, and the plurality of reference samples. Therefore, the image model may be updated in an accurate and effective way.
