Dr. Winstead delivered a presentation at Bretagne Telecom, titled "Recent results on bit-flipping LDPC decoders." The slides and associated article links are available at the bottom of this announcement. This presentation offered a summary of our work on the Noisy Gradient Descent Bit Flipping (NGDBF) algorithm, which was invented by PhD student Gopal Sundar.
All electronic and computing systems are sensitive to various types of errors. For several decades, a simple procedure known as Triple Modular Redundancy (TMR) has been a leading technique for producing highly error-resilient systems (see the Wikipedia entry on TMR). TMR is based on a simple idea: make three independently-running copies of any computing module or system. Each copy gets the same inputs. Then, at the output, take a majority vote to determine the answer.
