PATTERN_CITY_BLOCK_CVIP
pattern_city_block_cvip() - takes two csv files as input, test and training set, then calculates the city block distance metric by comparing each vector in the test set to each in the training set.
Contents
SYNTAX
d = pattern_city_block_cvip(file_tt, file_tr)
Input Parameters include:
- file_tt - Name of the test set file. A CSV file with a predefined structure.
- file_tr - Name of the training set file. A CSV file with a predefined structure.
Output Parameters include :
- d - A matrix containing the distances between each vector in the test set to each vector in the training set. Each column represents a vector in training set. Each row represents a vector in test set.
DESCRIPTION
Using city block metric, the function calculates the distance between the vectors in training set and the test set. The distances are returned in a matrix form whose rows represent the test vectors and columns represent the training vectors.
