    摘要： A storage record engine implemented on a storage system is provided. The storage record engine further organizes hosted storage of the storage system into superblocks and chunks organized by respective metadata, the chunks being further organized into chunk segments amongst superblocks. Persistent storage operations may cause modifications to the metadata, which may be recorded in a transaction log, records of which may be replayed to commit the modifications to hosted storage. The replay functionality may establish recovery of data following a system failure, wherein replay of records of transaction logs in a fashion interleaved with checkpoint metadata avoids preemption of normal storage device activity during a recovery process, and improves responsiveness of the storage system from the perspective of end devices.

    摘要： The present disclosure relates to a system and a method for data protection. In some embodiments, an exemplary method for data encoding includes: receiving a data bulk; performing an erasure coding (EC) encoding on the data bulk to generate one or more EC codewords; distributing a plurality of portions of each EC codeword of the one or more EC codewords across a plurality of solid-state drives (SSDs); performing, at each SSD of the plurality of SSDs, an error correction coding (ECC) encoding on portions of the one or more EC codewords distributed to the SSD to generate an ECC codeword; and storing, in each SSD of the plurality of SSDs, the ECC codeword.

    摘要： Improved convolutional layers for neural networks can obtain an input feature map comprising groups of channels. Each group of channels can include one or more channels having a predetermined size. The predetermined sizes can differ between the groups. The convolutional layer can generate, for each one of the groups of channels, an output channel. Generation of the output channel can include resizing the channels in the remaining groups of channels to match the predetermined size of the each one of the groups of channels. Generation can further include combining the channels in the each one of the groups with the resized channels and applying the combined channels to a convolutional sub-layer to generate the output channel.

    摘要： A speech recognition method including performing speech recognition on an inputted speech to obtain a first text, correcting the first text according to an obtained mapping relationship between words in different languages to obtain at least one second text, and in response to determining that the at least one second text corresponds to the same language, outputting the first text, or in response to determining that the at least one second text corresponds to different languages, determine an outputted text according to first probability values corresponding to each of the at least one second text. By combining the mapping relationships between words in different languages in correcting the initial ASR result, the present application ensures the accuracy of the final speech recognition result.
