摘要:

提出了一种改进置信传播算法的深度学习方法。该方法通过对Tanner图的边赋予权值来推广标准的置信传播算法。然后使用深度学习技术训练这些边缘。置信传播算法的一个众所周知的特性是性能与所发送的码字无关。我们的新方法的一个关键属性是我们的解码器保留了这个属性。此外,这个属性允许我们只学习单个码字,而不是指数数量的码字。对各种高密度奇偶检验码的置信传播算法的改进。

英文摘要:

A novel deep learning method for improving the belief propagation algorithm is proposed. The method generalizes the standard belief propagation algorithm by assigning weights to the edges of the Tanner graph. These edges are then trained using deep learning techniques. A well-known property of the belief propagation algorithm is the independence of the performance on the transmitted codeword. A crucial property of our new method is that our decoder preserved this property. Furthermore, this property allows us to learn only a single codeword instead of exponential number of code-words. Improvements over the belief propagation algorithm are demonstrated for various high density parity check codes.
