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.

Making a better TMR

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.
