Novel Architectures for Unsupervised Information Bottleneck based Speaker Diarization of Meetings
Nauman Dawalatabad, Srikanth Madikeri, C. Chandra Sekhar +1
Speaker diarization is an important problem that is topical, and is especially useful as a preprocessor for conversational speech related applications. The objective of this paper…
Unsupervised Deep Metric Learning via Orthogonality based Probabilistic Loss
Ujjal Kr Dutta, Mehrtash Harandi, Chellu Chandra Sekhar
Metric learning is an important problem in machine learning. It aims to group similar examples together. Existing state-of-the-art metric learning approaches require class labels t…
Affinity guided Geometric Semi-Supervised Metric Learning
Ujjal Kr Dutta, Mehrtash Harandi, Chellu Chandra Sekhar
In this paper, we revamp the forgotten classical Semi-Supervised Distance Metric Learning (SSDML) problem from a Riemannian geometric lens, to leverage stochastic optimization with…
