WebJun 9, 2024 · 5. Fisher Score. This is a filter method that uses mean and variance to rank the features. Features with similar values in their instances of the same class and different values to instances from different classes are considered best. Like the previous univariate methods, it evaluates features individually, and it cannot handle feature redundancy. WebMar 10, 2016 · The Wagner–Fischer algorithm is a dynamic programming algorithm that computes the edit distance between two strings of characters. Both using a matrix, and I don't see the difference? Is the difference the backtracking or is there no further difference by the fact that one is the "literature" and the other one is the programming?
