High-resolution screenshots are crowded with distractors, and vision-language models tend to favour visible text over icons, even when an icon is the real target. DiMo-GUI is a training-free, plug-and-play inference… 2. **[Thinking with Sound: Audio Chain-of-Thought Enables Multimodal Reasoning in Large Audio-Language Models](https://md.research.elamur.ai/free/en/papers/xiong-2025-thinking-sound-audio-chain-thought/)** *(2025 · 6 citations)* Large Audio-Language Models (LALMs) turn a recording into a fixed set of embeddings once. After that step they cannot go back to the signal. Because of this, they perform poorly when audio is noisy or degraded, or when a task depends on fine acoustic detail. The authors propose Thinking-with-Sound (TwS), a framework… 3. **[Mapping the Minds of LLMs: A Graph-Based Analysis of Reasoning LLMs](https://md.research.elamur.ai/free/en/papers/xiong-2025-mapping-minds-llms-graph-based/)** *(2025 · 5 citations)* Large Reasoning Models (LRMs) such as DeepSeek-R1 produce long Chain-of-Thought traces, yet they often behave erratically. 4. **[Vulnerability of LLMs to Vertically Aligned Text Manipulations](https://md.research.elamur.ai/free/en/papers/li-2025-vulnerability-llms-vertically-aligned-text/)** *(2025 · 5 citations)* The paper asks whether decoder-based LLMs are as vulnerable as encoder models like BERT when some words in a text are written vertically, one character per line. 5. **[Beyond Query Bias: Candidate-Aware Iterative Refinement for Zero-Shot Composed Image Retrieval](https://md.research.elamur.ai/free/en/papers/sun-2026-beyond-query-bias-candidate-aware/)** *(2026)* The paper addresses a weakness in Zero-Shot Composed Image Retrieval (ZS-CIR), where a system must find a target image from a reference image plus a modification text without task-specific training. 6. **[Mitigating Coordinate Prediction Bias from Positional Encoding Failures](https://md.research.elamur.ai/free/en/papers/tao-2026-mitigating-coordinate-prediction-bias-positional/)** *(2026)* Multimodal LLMs that output click coordinates as digit strings often drift on high-resolution screenshots, because visual positional encodings (VPEs) lose grounding strength in long visual contexts. ## All works 7 works of theirs in our library, the most cited first; 6 with a page here, the others link their original until we summarise them. 1. **[A Unified 3D Human Motion Synthesis Model via Conditional Variational Auto-Encoder ↗](https://doi.org/10.1109/iccv48922.2021.01144) IEEE/CVF International Conference on Computer Vision (ICCV) · no summary yet**Yujun Cai et al.*2021 · 68 citations* 2. **[DiMo-GUI: Advancing Test-time Scaling in GUI Grounding via Modality-Aware Visual Reasoning](https://md.research.elamur.ai/free/en/papers/wu-2025-dimo-gui-advancing-test-time/) [Conference on Empirical Methods in Natural Language Processing (EMNLP)](https://md.research.elamur.ai/free/en/venues/emnlp/)**Hang Wu, Hongkai Chen, Yujun Cai, et al.*2025 · 8 citations* 3.
