Correct predictions are in blue. If we detect only a subset of a labelled sentence, we highlight the caught part as blue, the missing part light blue. False positives are in green and false negatives are in red.

Problem 036 (Error correcting code) — Constraint detection

A fixed length error correcting code C of length n over an alphabet F is a set of strings from Fn . Given two strings from Fn we can define the distance between them . The most commonly used distance is the Hamming distance , defined as the number of positions where the strings differ . Using this we define the minimum distance of C as the minimum of the distances between distinct pairs of strings from C . There are a number of other distances which can be used , for example the `` Lee distance '' . When F = -LCB- 0,1 , - , n-1 -RCB- the Lee distance between a , b in F is defined as min -LRB- | a-b | , n - | a-b | -RRB- . For two vectors x and y defined over Fn , the Lee distance is calculated by summing the Lee distance of the pairs xi , yi . Most commonly F = -LCB- 0,1,2,3 -RCB- as this case proves useful in a number of areas . Following standard practice we represent the code as an $ n \ times | C | $ matrix , where each row contains one element of the code . The difference constraint is enforced between pairs of rows .
