Abstract: Apparatuses, systems, and techniques generating one or more cluster performance evaluation metrics that allow for evaluation of the performance of an unsupervised natural language processing clustering algorithms to be used with unlabeled data. At least one embodiment pertains to methods of generating one or more cluster performance evaluation metrics based, at least in part, on one or more vectors generated by one or more neural networks to indicate a relationship among members of one or more clusters of data generated using the one or more data clustering algorithms, according to various novel techniques described herein.
