| Challenge: | Existing topic models rely on probabilistic models to uncover themes within document collections, but are they the only option? |
| Approach: | They propose a way to cluster pre-trained word embeddings while incorporating document information for weighted clustering and reranking top words. |
| Outcome: | The proposed approach performs as well as classical topic models, but with lower runtime and computational complexity. |

A Disentangled Adversarial Neural Topic Model for Separating Opinions from Plots in User Reviews (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing topic models may extract topics associated with writers’ subjective opinions mixed with those related to factual descriptions. |
| Approach: | They propose a neural topic model combined with adversarial training to disentangle opinion topics from plot and neutral ones. |
| Outcome: | The proposed model shows improved coherence and variety of topics, consistent disentanglement rate, and superior sentiment classification performance to other supervised topic models. |
Sparse Parallel Training of Hierarchical Dirichlet Process Topic Models (2020.emnlp-main)
Copied to clipboard
| Challenge: | To scale non-parametric extensions of probabilistic topic models, practitioners rely increasingly on parallel and distributed systems. |
| Approach: | They propose a data-parallel sampler that utilizes all available sources of sparsity found in natural language to control memory requirements and computational complexity. |
| Outcome: | The proposed sampler is able to train a hierarchical Dirichlet process topic model on a well-known corpus (PubMed) with 8m documents and 768m tokens, using a single multi-core machine in under four days. |

| Challenge: | a common use of NLP is to facilitate the understanding of large document collections. |
| Approach: | They propose to use large language models to replace probabilistic topic models in real-world applications. |
| Outcome: | The proposed model generates more human-readable topics and shows higher average win probabilities than traditional models for data exploration. |
Benchmarking Neural Topic Models: An Empirical Study (2021.findings-acl)
Copied to clipboard
| Challenge: | Neural topic modeling has been attracting much attention recently due to its ability to leverage the advantages of both neural networks and probabilistic topic models. |
