Fig. 9From: Unsupervised adaptation of PLDA models for broadcast diarizationSchematic for unsupervised longitudinal adaptation for the episodes n−1, n, and \(n+1.\mathcal {M}_{\mathrm {n-2}}, \mathcal {M}_{n-1}, \mathcal {M}_{n}\), and \(\mathcal {M}_{n+1}\) represent the adapted models for episodes n−2,n−1, n, and n+1. Φn−1,Φn, and Φn+1 are the i-vectors from each episodeBack to article page
