Deep Embedded Clustering (DEC) [49] is a representative method that uses an auto-encoder as the network architecture and a cluster-assignment hardening loss for regularization. Li et al. [26] proposed a similar network architecture but with a boosted discrimination module to gradually enforce cluster purity.

Clustering with Deep Learning: Taxonomy and New Methods
WebA mutual distance loss is deployed on the Gaussian priors to force different priors to become more separable. Also, a clustering assignment hardening loss is jointly … WebAug 1, 2024 · As for Part II, cluster assignment hardening is further applied to the low-dimensional representation to make it cluster-friendly and generate discriminative clusters. By jointly optimizing reconstruction loss and clustering loss, the cluster assignment of each trajectory can be directly obtained, together with the corresponding cluster centroids. WebNov 1, 2024 · 3.2 Clustering Loss. We followed DEC [] to adapt the soft assignment based on Student’s t-distribution to measure the easiness of a sample.Cluster assignment hardening is a commonly used cluster loss function that is composed of the KL divergence between the soft assignment Q and its auxiliary target distribution P.This cluster … hr block uniontown
