3. Export_details_labels (Exporting the labels detailed results in files)
4. Export_convergence (Exporting the covergence plots)
5. Export_boxplot (Exporting the box plots)
auto_cluster : boolean, default = True
Choose whether the number of clusters is detected automatically.
If True, select one of the following: 'supervised', 'CH', 'silhouette', 'elbow', 'gap', 'min', 'max', 'median' for n_clusters.
If False, specify a list of integers for n_clusters.
n_clusters : string, or list, default = 'supervised'
A list of the number of clusters for the datasets in dataset_List
Other values can be considered instead of specifying the real value, which are as follows:
- supervised: The number of clusters is derived from the true labels of the datasets
- elbow: The number of clusters is automatically detected by elbow method
- gap: The number of clusters is automatically detected by gap analysis methos
- silhouette: The number of clusters is automatically detected by silhouette coefficient method
- CH: The number of clusters is automatically detected by Calinski-Harabasz index
- DB: The number of clusters is automatically detected by Davies Bouldin index
- BIC: The number of clusters is automatically detected by Bayesian Information Criterion score
- min: The number of clusters is automatically detected by the minimum value of the number of clusters detected by all detection techniques
- max: The number of clusters is automatically detected by the maximum value of the number of clusters detected by all detection techniques
- median: The number of clusters is automatically detected by the median value of the number of clusters detected by all detection techniques
- majority: The number of clusters is automatically detected by the majority vote of the number of clusters detected by all detection techniques
labels_exist : boolean, default = True
Specify if labels exist as the last column of the csv file of the datasets in dataset_List
if the value is False, the following hold:
- supervised value for n_clusters is not allowed
- experiments, and experiments_details files contain only the evaluation measures for
"SSE","TWCV","SC","DB","DI","STDev"
- Export_boxplot is set for "SSE","TWCV","SC","DB","DI","STDev"
metric : string, default = 'euclidean'
The metric to use when calculating the distance between points if applicable for the objective function selected.
It must be one of the options allowed by scipy.spatial.distance.pdist for its metric parameter
