Interpret the TN,TF,FN,TN in the clustering questions clearly

TN (True Negative): The number of data points that are correctly identified as not belonging to any cluster.

TF (True False): This term is not commonly used in clustering. It may refer to a data point that is correctly classified as belonging to a particular cluster.

FN (False Negative): The number of data points that actually belong to a cluster but are not identified as such by the clustering algorithm.

TP (True Positive): This term is not commonly used in clustering. It may refer to a data point that is correctly classified as belonging to a particular cluster.

In summary, TN and FN are the two most commonly used terms in clustering. They represent the correct and incorrect identification of data points that belong to a cluster, respectively.
