Hyper-Graph Network Decoders for Algebraic Block Codes

Abstract:

In one embodiment, a method includes inputting an encoded message with noise to a neural-networks model comprising a variable and a check layers of nodes, each node being associated with at least one weight and a hyper-network node, updating the weights associated with the variable layer of nodes by processing the encoded message using the hyper-network nodes associated with the variable layer of nodes, generating a first set of outputs by processing the encoded message using the variable layer of nodes and their respective updated weights, updating the weights associated with the check layer of nodes by processing the first set of outputs using the hyper-network nodes associated with the check layer of nodes, and generating a decoded message without noise using the neural-networks model by using at least the first set of outputs and the check layer of nodes and their respective updated weights.
