Latent Dirichlet Allocation in Generative Adversarial Networks

open access: yesCoRR, 2018
We study the problem of multimodal generative modelling of images based on generative adversarial networks (GANs). Despite the success of existing methods, they often ignore the underlying structure of vision data or its multimodal generation characteristics.

Latent Dirichlet Allocation for Automatic Document Categorization [PDF]

open access: yes, 2009
In this paper we introduce and evaluate a technique for applying latent Dirichlet allocation to supervised semantic categorization of documents. In our setup, for every category an own collection of topics is assigned, and for a labeled training document only topics from its category are sampled.

Latent Beta-Liouville Probabilistic Modeling for Bursty Topic Discovery in Textual Data

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference
Topic modeling has become a fundamental technique for uncovering latent thematic structures within large collections of textual data. However, conventional models often struggle to capture the burstiness of topics.

Profiling heterogeneity of Alzheimer's disease using white-matter impairment factors

open access: yesNeuroImage: Clinical, 2018
The clinical presentation of Alzheimer's disease (AD) is not unitary as heterogeneity exists in the disease's clinical and anatomical characteristics. MRI studies have revealed that heterogeneous gray matter atrophy patterns are associated with specific ...

Author Identification Using Latent Dirichlet Allocation

open access: yes, 2018
We tackle the task of author identification at PAN 2015 through a Latent Dirichlet Allocation (LDA) model. By using this method, we take into account the vocabulary and context of words at the same time, and after a statistical process find to what extent the relations between words are given in each document; processing a set of documents by LDA ...

Modeling Word Relatedness in Latent Dirichlet Allocation

open access: yesCoRR, 2014
Standard LDA model suffers the problem that the topic assignment of each word is independent and word correlation hence is neglected. To address this problem, in this paper, we propose a model called Word Related Latent Dirichlet Allocation (WR-LDA) by incorporating word correlation into LDA topic models.
