One of Donald Knuth's personally-designed reward checks, with the recipient's name and design details censored to deter forgeries. Knuth reward checks are checks or check-like certificates awarded by computer scientist Donald Knuth for finding technical, typographical, or historical errors, or making substantial suggestions for his publications.
That is, if a student answer's "x" for part a, the correct answer to part b is "f(x)." No matter what the student puts for part a, the corresponding answer for part b can be calculated quickly. Lawson-Perfect discloses that this system cannot identify "why" a student made an error, but maintains that it is generally successful in providing fair ...
It is a device to be used only in extreme cases where errors severe enough to cause misunderstanding are detected too late to correct in the normal way but before the finished book is distributed. Then the errors may be listed with their locations and their corrections on a sheet that is tipped in , either before or after the book is bound, or ...
The question should have read “metres per second” not “m per second” as it did. A senior maths figure told the Herald Sun the latest correction “shouldn’t have been needed — you say either m/s or metres per second. You don’t say m per second”. [13] Three more issues arose since students sat the exam.
In correcting errors, correction is a post-production exercise and basically deals with the linguistic errors. [3] Often in the form of feedback, it draws learners' attention to the mistakes they have made and acts as a reminder of the correct form of language.
The on-line textbook: Information Theory, Inference, and Learning Algorithms, by David J.C. MacKay, contains chapters on elementary error-correcting codes; on the theoretical limits of error-correction; and on the latest state-of-the-art error-correcting codes, including low-density parity-check codes, turbo codes, and fountain codes.
The private company that processes many bank-to-bank electronic transfers said a 'processing error' last week led to payment delays on roughly 850,000 transactions.
Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.
