KV: A Self-Refining KV Cache
Johannes Wesch, Danni Liu, Jan Niehues
The memory footprint of the key-value (KV) cache constrains the practical use of long-context models, and it dominates cost when one prefilled context must later serve many differe…
Predicting Steering Vectors and Adapter Weights for Few-Shot Author-Style Transfer
Leonard Popp, Danni Liu, Supriti Sinhamahapatra +1
Adapting large language models to an individual author's style from a few examples is challenging, and scientific writing sharpens the difficulty: formal conventions leave little s…
From Speech to Interaction: Analyzing Multimodal Systems in Cocktail-Party Scenarios
Thai-Binh Nguyen, Zhaolin Li, Jan Niehues +1
Humans have the remarkable ability to engage in spontaneous informal conversations and selectively attend to individual speakers while filtering out competing speech from nearby co…
MUSCAT: MUltilingual, SCientific ConversATion Benchmark
Supriti Sinhamahapatra, Thai-Binh Nguyen, Yiğit Oğuz +3
The goal of multilingual speech technology is to facilitate seamless communication between individuals speaking different languages, creating the experience as though everyone were…
Multimodal In-context Learning for ASR of Low-resource Languages
Zhaolin Li, Jan Niehues
Automatic speech recognition (ASR) still covers only a small fraction of the world's languages, mainly due to supervised data scarcity. In-context learning (ICL) with large languag…
Sigmoid Head for Quality Estimation under Language Ambiguity
Tu Anh Dinh, Jan Niehues
Language model (LM) probability is not a reliable quality estimator, as natural language is ambiguous. When multiple output options are valid, the model's probability distribution…
BOOM: Beyond Only One Modality KIT's Multimodal Multilingual Lecture Companion
Sai Koneru, Fabian Retkowski, Christian Huber +5
The globalization of education and rapid growth of online learning have made localizing educational content a critical challenge. Lecture materials are inherently multimodal, combi…
OmniFusion: Simultaneous Multilingual Multimodal Translations via Modular Fusion
Sai Koneru, Matthias Huck, Jan Niehues
There has been significant progress in open-source text-only translation large language models (LLMs) with better language coverage and quality. However, these models can be only u…
Conditions for Catastrophic Forgetting in Multilingual Translation
Danni Liu, Jan Niehues
Fine-tuning multilingual foundation models on specific languages often induces catastrophic forgetting, degrading performance on languages unseen in fine-tuning. While this phenome…
From Slides to Chatbots: Enhancing Large Language Models with University Course Materials
Tu Anh Dinh, Philipp Nicolas Schumacher, Jan Niehues
Large Language Models (LLMs) have advanced rapidly in recent years. One application of LLMs is to support student learning in educational settings. However, prior work has shown th…
Knockout LLM Assessment: Using Large Language Models for Evaluations through Iterative Pairwise Comparisons
Isik Baran Sandan, Tu Anh Dinh, Jan Niehues
Large Language Models (LLMs) have shown to be effective evaluators across various domains such as machine translations or the scientific domain. Current LLM-as-a-Judge approaches r…
In-context Language Learning for Endangered Languages in Speech Recognition
Zhaolin Li, Jan Niehues
With approximately 7,000 languages spoken worldwide, current large language models (LLMs) support only a small subset. Prior research indicates LLMs can learn new languages for cer…
KIT's Low-resource Speech Translation Systems for IWSLT2025: System Enhancement with Synthetic Data and Model Regularization
Zhaolin Li, Yining Liu, Danni Liu +6
This paper presents KIT's submissions to the IWSLT 2025 low-resource track. We develop both cascaded systems, consisting of Automatic Speech Recognition (ASR) and Machine Translati…
Middle-Layer Representation Alignment for Cross-Lingual Transfer in Fine-Tuned LLMs
Danni Liu, Jan Niehues
While large language models demonstrate remarkable capabilities at task-specific applications through fine-tuning, extending these benefits across diverse languages is essential fo…
Are Generative Models Underconfident? Better Quality Estimation with Boosted Model Probability
Tu Anh Dinh, Jan Niehues
Quality Estimation (QE) is estimating quality of the model output during inference when the ground truth is not available. Deriving output quality from the models' output probabili…
Quality-Aware Decoding: Unifying Quality Estimation and Decoding
Sai Koneru, Matthias Huck, Miriam Exel +1
Quality Estimation (QE) models for Neural Machine Translation (NMT) predict the quality of the hypothesis without having access to the reference. An emerging research direction in…
