Augmenting word2vec with latent Dirichlet allocation within a clinical application

NAACL 2019 · Akshay Budhkar, Frank Rudzicz ·

This paper presents three hybrid models that directly combine latent Dirichlet allocation and word embedding for distinguishing between speakers with and without Alzheimer's disease from transcripts of picture descriptions. Two of our models get F-scores over the current state-of-the-art using automatic methods on the DementiaBank dataset.
