WebOct 14, 2024 · Abstract: Multi-label classification refers to the task of outputting a label set whose size is unknown for each unseen instance. The challenges of using the random walk method are how to construct the random walk graph and make prediction for testing instances. In this paper, we propose a multi-label classification method based on the … WebApr 19, 2016 · I could then modify parameters and restart the same random sequence with a different degree of interaction by using the same seed. Random number generators form a long non-repeating sequence based upon an initial seed value. I could also use a different seed value and rerun the data - giving me a two-dimensional view. diameter of a softball in inches
