A Temporal Extension of Latent Dirichlet Allocation for Unsupervised Acoustic Unit Discovery

2022 · arXiv (Cornell University)

Latent Dirichlet allocation (LDA) is widely used for unsupervised topic modelling on sets of documents. No temporal information is used in the model. However, there is often a relationship between the corresponding topics of consecutive …

On the link between generative semi-supervised learning and generative open-set recognition

2023 · Scientific African

This study investigates the relationship between semi-supervised learning (SSL, which is training off partially labelled datasets) and open-set recognition (OSR, which is classification with simultaneous novelty detection) under the context of generative adversarial networks (GANs). …
