- Abstract: Distributional text clustering delivers semantically informative
representations and captures the relevance between each word and semantic
clustering centroids. We extend the neural text clustering approach to text
classification tasks by inducing cluster centers via a latent variable model
and interacting with distributional word embeddings, to enrich the
representation of tokens and measure the relatedness between tokens and each
learnable cluster centroid. The proposed method jointly learns word clustering
centroids and clustering-token alignments, achieving the state of the art
results on multiple benchmark datasets and proving that the proposed
cluster-token alignment mechanism is indeed favorable to text classification.
Notably, our qualitative analysis has conspicuously illustrated that text
representations learned by the proposed model are in accord well with our
intuition.

We propose a novel Classification-Enhanced Iterative Learning framework for short text clustering.
In each iteration, we first adopt a language model to retrieve the initial text representations.
After strict data filtering and aggregation processes, samples with clean category labels are retrieved, which serve as supervision information.
Finally, the updated language model with improved representation ability is used to enhance clustering in the next iteration.

We extend the mainstream contrastive learning paradigm to a cluster-level scheme, where all the data subjected to the same cluster contribute to a unified representation.
We define a set of categorical variables as clustering assignment confidence, which links the instance-level learning track with the cluster-level one.
By reparametrizing the assignment variables, TCC is trained end-to-end, requiring no alternating steps.

On the other hand, a novel graph-based contrastive learning strategy is proposed to learn more compact clustering assignments.
