LDA-style probabilistic models need a fixed topic count and bag-of-words input. Neural models are heavily parameterized, trained in batch, and tend to forget earlier topics as new data streams in. Hierarchies are also often added only after flat clustering. CobwebTM addresses… 2. **[Grounded Concreteness: Human-Like Concreteness Sensitivity in Vision–Language Models](https://md.research.elamur.ai/free/en/papers/roy-2026-grounded-concreteness-human-like-concreteness/)** *(2026)* The paper asks whether multimodal training gives language models a more human-like sense of how concrete or abstract words are, even when the models only receive text. ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[Learning Cognitive Models Using Neural Networks ↗](https://doi.org/10.1007/978-3-319-93843-1_4) Lecture notes in computer science · no summary yet**Devendra Singh Chaplot et al.*2018 · 12 citations* 2. **[CobwebTM: Probabilistic Concept Formation for Lifelong and Hierarchical Topic Modeling](https://md.research.elamur.ai/free/en/papers/singaravadivelan-2026-cobwebtm-probabilistic-concept-formation-lifelong/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Karthik Singaravadivelan, Anant Gupta, Zekun Wang, et al.*2026* 3. **[Grounded Concreteness: Human-Like Concreteness Sensitivity in Vision–Language Models](https://md.research.elamur.ai/free/en/papers/roy-2026-grounded-concreteness-human-like-concreteness/) [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/)**Aryan Roy, Zekun Wang, Christopher J.
