You can also accept slower search times in favour of reduced loading times, memory usage, and disk IO. Next, we will understand what are the factors to be considered to conclude the best K. First let us try to understand what exactly does K influence in the algorithm. BS can either be RC or GS and nothing else. Doing so will print to the standard output the k most likely labels for each line. Once the model was trained, you can evaluate it by computing the precision and recall at k (P@k and R@k) on a test set using: The argument k is optional, and is equal to 1 by default.
