• Abstract summary: In text classification tasks, fine tuning pretrained language models like BERT and GPT-3 yields competitive accuracy. General topic modeling methods possess the advantage of analyzing documents to extract meaningful patterns of words without the need of pretraining. We develop the Knowledge Distillation Semi-supervised Topic Modeling (KDSTM) to leverage topic modeling's unsupervised insights extraction on text classification tasks.

• Abstract: In text classification tasks, fine tuning pretrained language models like BERT and GPT-3 yields competitive accuracy; however, both methods require pretraining on large text datasets. In contrast, general topic modeling methods possess the advantage of analyzing documents to extract meaningful patterns of words without the need of pretraining. To leverage topic modeling's unsupervised insights extraction on text classification tasks, we develop the Knowledge Distillation Semi-supervised Topic Modeling (KDSTM). KDSTM requires no pretrained embeddings, few labeled documents and is efficient to train, making it ideal under resource constrained settings. Across a variety of datasets, our method outperforms existing supervised topic modeling methods in classification accuracy, robustness and efficiency and achieves similar performance compare to state of the art weakly supervised text classification methods.

To evaluate the quality of the extracted representations, we use both intrinsic and extrinsic evaluation methods. The pretrained models are fine-tuned to achieve state-of-the-art results in tasks such as writer identification, gender classification, and handedness classification.

  For large-scale IT corpora with hundreds of classes organized in a hierarchy, the task of accurate classification of classes at the higher level in the hierarchies is crucial. In the business world, an efficient and explainable ML model is preferred over an expensive black-box model, especially if the performance increase is marginal. Despite the widespread use of PLMs, there is a lack of a clear and well-justified need to as why these models are being employed for domain-specific text classification.
