Question:

Example 7.8 showed the use of error-correcting codes for a multiclass classification problem having four classes.

a. Suppose that, given an unknown tuple to label, the seven trained binary classifiers collectively output the codeword 0101110, which does not match a codeword for any of the four classes. Using error correction, what class label should be assigned to the tuple?

b. Explain why using a 4-bit vector for the codewords is insufficient for error correction.

Example 7.8. Multiclass classification with error-correcting codes. Consider the 7-bit codewords associated
