The application provides an LDPC code decoding method and device, electronic equipment and storage medium. The method comprises the following steps: obtaining an input code word, a grouped check matrix and an initial confidence of an LDPC code, wherein the grouped check matrix is obtained by grouping an original check matrix according to a preset condition; presetting two initial quantization values with a given magnitude bit width, calculating an initial companion based on the input code word and the grouped check matrix; starting from the initial companion and the two initial quantization values, performing decoding iteration column by column, updating a current column variable node in the iteration, obtaining a soft decision message and transmitting the soft decision message to a next column, updating an associated grouped check node, and performing post-processing compensation on an oscillation correctable code word; updating the companion after each column is updated and judging a decoding success condition; and outputting a result when the condition is met or a maximum iteration number is reached. The scheme can realize the collaborative optimization of decoding performance and hardware implementation efficiency.

The utility model relates to the technical field of machining and manufacturing, in particular to a grabbing robot rail type moving structure which comprises a rail system, a material conveying system, a moving platform, a grabbing robot and a control system. Cooperative operation of the multiple grabbing robots is achieved through the rail type moving structure, a single-line single-device mode is upgraded to a distributed cluster operation mode, operation efficiency is improved, meanwhile, single-point bottleneck is eliminated, material conveying and grabbing rhythm separation is achieved, restriction of starting and stopping of a traditional single device on a whole production line is avoided, production continuity is improved, and production cost is reduced. The method has wide applicability in the fields of industrial automation, logistics storage and the like, and economic benefits are remarkable.

The invention discloses an SM9-based verifiable fair broadcast proxy re-encryption method and a hardware architecture thereof, and relates to the technical field of information security. The re-encryption method comprises the following steps: encrypting an original message based on SM9 to generate an initial ciphertext, generating a re-encryption key based on a private key of a data owner and an authorized user identifier set, and sending the initial ciphertext and the re-encryption key to a proxy server; the proxy server performs re-encryption operation on the initial ciphertext based on the re-encryption key to generate a re-encrypted ciphertext, and broadcasts the re-encrypted ciphertext to all authorized users, and the authorized users perform decryption verification on the received re-encrypted ciphertext by using own private keys; and a public verifier can perform verification arbitration on the re-encrypted ciphertext based on a non-interactive zero-knowledge proof protocol. According to the re-encryption method provided by the invention, a multi-user application scene is expanded, direct verification of the re-encrypted ciphertext is realized, and a fair and neutral dispute judgment rule is established.

A neural network system is provided that implements a generative model for autoregressively generating a distribution of a plurality of current filterbank samples of an audio signal, where the current samples correspond to a current time bin, and each current sample corresponds to a channel of the filterbank. The system includes a hierarchy of a plurality of neural network processing layers ordered from a top layer to a bottom layer, each layer trained to generate conditioning information based on previous filterbank samples, and for at least each layer other than the top layer, also based on conditioning information from a higher layer in the hierarchy; and an output stage trained to generate a probability distribution based on previous samples of one or more previous time bins and conditioning information from the lowest processing layer.
