This code generate partitions for a multilabel dataset using the Jaccard Index similarity measure. We use HCLUST with 6 linkage metrics to generate several partitions. You may build the partition with the highest coefficient. This code also provide an analysis about the partitioning
Confirms if the folder .......
Copy this code and place it where you want. The folder configurations is "~/jaccard"
A file called datasets-original.csv must be in the root project folder. This file is used to read information about the datasets and they are used in the code. We have 90 multilabel datasets in this .csv file. If you want to use another dataset, please, add the following information about the dataset in the file:
| Parameter | Status | Description |
|---|---|---|
| Id | mandatory | Integer number to identify the dataset |
| Name | mandatory | Dataset name (please follow the benchmark) |
| Domain | optional | Dataset domain |
| Instances | mandatory | Total number of dataset instances |
| Attributes | mandatory | Total number of dataset attributes |
| Labels | mandatory | Total number of labels in the label space |
| Inputs | mandatory | Total number of dataset input attributes |
| Cardinality | optional | |
| Density | optional | |
| Labelsets | optional | |
| Single | optional | |
| Max.freq | optional | |
| Mean.IR | optional | |
| Scumble | optional | |
| TCS | optional | |
| AttStart | mandatory | Column number where the attribute space begins* |
| AttEnd | mandatory | Column number where the attribute space ends |
| LabelStart | mandatory | Column number where the label space begins |
| LabelEnd | mandatory | Column number where the label space ends |
| Distinct | optional | |
| xn | mandatory | Value for Dimension X of the Kohonen map |
| yn | mandatory | Value for Dimension Y of the Kohonen map |
| gridn | mandatory | X times Y value. Kohonen's map must be square |
| max.neigbors | mandatory | The maximum number of neighbors is given by LABELS -1 |
- Because it is the first column the number is always 1.
You need to have installed all the R packages required to execute this code on your machine. Check out which are needed in the file libraries.R. This code does not provide any type of automatic package installation! You can use the Conda environment that I created to perform this experiment. Below are the links to download the files.

To run, first enter the folder ~/jaccard/R in a terminal and the type: (check this information)
Rscript jaccard.R [number_dataset] [number_cores] [number_folds] [validation] [folder]
Where:
number_dataset is the dataset number in the datasets.csv file
number_cores is the number of cores that you wanto to use in paralel
number_folds is the number of folds you want for cross-validation
validation 0 if you dont want the validation set and 1 if you want
folder temporary folder like SHM or SCRATCH to speed up the process
