From Retrieval to Weights: Parametric Individualization of Small Language Models with Individual Text Corpora
Christoph Wigbels, Ali Abusaleh, Markus T. Jansen +2
We approach a cognitive simulation perspective on episodic and semantic memory in multiple-choice question answering by incorporating text from individual text corpora (ITC) into r…
Learning to Detect Cross-Modal Negation: An Analysis of Latent Representations and an Attention-Based Solution
Ali AbuSaleh, Leon Hammerla, Alexander Mehler
Detecting high-level semantic concepts like negation across modalities remains a challenge for current multimodal systems. We analyze this as a fundamental representation learning…
MMTM: Tri-Modal Topic Modeling for Long-Form Video via Similarity-Gated Fusion
Ali Abusaleh, Bhuvanesh Verma, Alexander Mehler
We introduce MMTM, a modular pipeline for topic discovery in long-form video that integrates speech recognition, audio and visual embeddings, and BERTopic clustering through a dete…
From Early Encoding to Late Suppression: Interpreting LLMs on Character Counting Tasks
Ayan Datta, Mounika Marreddy, Alexander Mehler +2
Large language models (LLMs) exhibit failures on elementary symbolic tasks such as character counting in a word, despite excelling on complex benchmarks. Although this limitation h…
You Shall Know a Tool by the Traces it Leaves: The Predictability of Sentiment Analysis Tools
Daniel Baumartz, Mevlüt Bagci, Alexander Henlein +3
If sentiment analysis tools were valid classifiers, one would expect them to provide comparable results for sentiment classification on different kinds of corpora and for different…
The Spatial Semantics of Iconic Gesture
Andy Lücking, Alexander Henlein, Alexander Mehler
The current multimodal turn in linguistic theory leaves a crucial question unanswered: what is the meaning of iconic gestures, and how does it compose with speech meaning? We argue…
