概要
- 論文の詳細を見る
The conjecture of Rujan on error-correcting codes is proven. Errors in decoding of signals transmitted through noisy channels assume the smallest values when signals are decoded at a particular finite temperature. This finite-temperature decoding is compared with the conventional maximum likelihood decoding which corresponds to the T= 0 case. The method of gauge transformation in the spin glass theory is useful in this argument.
