In computer science and telecommunication, Hamming codes are a family of linear error-correcting codes. Hamming codes can detect one-bit and two-bit errors, or correct one-bit errors without detection of uncorrected errors. By contrast, the simple parity code cannot correct errors, and can detect only an odd number of bits in error. Hamming codes are perfect codes, that is, they achiev… WebDefinition and parameters [ edit] A linear code of length n and dimension k is a linear subspace C with dimension k of the vector space where is the finite field with q elements. Such a code is called a q -ary code. If q = 2 or q = 3, the code is described as a binary code, or a ternary code respectively. The vectors in C are called codewords.

The distance between two strings of equal length is the number of bit positions at which the bits are different. For example, suppose there are two strings, 1101 1001 and 1001 1101. 11011001 ⊕ 10011101 = 01000100. Since, this contains two 1s, the Hamming distance, d … diamondbacks stadium swimming pool

"Web@mark My idea does not include Hamming loss. In fact, you cannot use Hamming loss as a criterion for optimizing a model's weights with Stochastic Gradient Descend (SGD): The gradient of the Hamming loss is zero almost everywhere. Therefore, you must use a "proxy loss", e.g., cross entropy. – " - Binary hamming distance
