Large Language Models (LLMs) have revolutionized the modern society significantly with the numerous advanced interactions between humans and AI agents, whereas the usage of most large language models including ChatGPT are not friendly open-sourced and must require users paying a lot for such AI service continuously. Therefore, deploying open-sourced large language models on local servers can be considered as an efficient method to design and implement creative embodied AI algorithms with lower cost and more stable free usage. Inspired by this ordinary motivation, we originally propose and implement the “Socratic Models-ChatGLM”, which is a well-performed algorithm for multi-modal interactive control of robotic arm based on offline large language models via the facile PyBullet platform, even presents extraordinary potential to address complicated text-image multi-step long-horizon robotic manipulation tasks.

We propose a framework for privacy-preserving argumentative explanations using homomorphic encryption. This method applies the Cheon-Kim-Kim-Song scheme, along with a soft k-means adapted for encrypted computation, to generate explanations without exposing sensitive data. By leveraging GPU acceleration, speedups of approximately 470–670 times were achieved compared with CPU execution. Experimental results show that explanation fidelity is maintained for small- to medium-scale models, whereas significant degradation occurs in larger models. These findings suggest that our study provides an initial step toward enabling secure and trustworthy argumentative explanations under encryption while also highlighting the challenges that remain for generalizability to more complex models.

We propose HyMoERec, a novel sequential recommendation framework that addresses the limitations of uniform Position-wise Feed-Forward Networks in existing models. Current approaches treat all user interactions and items equally, overlooking the heterogeneity in user behavior patterns and diversity in item complexity. HyMoERec initially introduces a hybrid mixture-of-experts architecture that combines shared and specialized expert branches with an adaptive expert fusion mechanism for the sequential recommendation task. This design captures diverse reasoning for varied users and items while ensuring stable training. Experiments on MovieLens-1M and Beauty datasets demonstrate that HyMoERec consistently outperforms state-of-the-art baselines.

Question generation is the task of natural language
processing where the goal is to generate fluent,
grammatically correct, error-free questions based on a
given input context and optionally an answer. Multi-hop
question generation is a more complex task compared to
traditional single-hop question generation, as it requires
reasoning over multiple information from multiple input
contexts in generating multi-hop questions. In this paper,
we have addressed the challenge of building a multi-hop
question generation system by combining the knowledge
graphs with large language models. We have designed a
framework KG4QG (Knowledge Graph for Question Generation),
where knowledge graphs are generated from the input
contexts. For the knowledge graph embedding, we have used
Graph Attention Network, and for input text embedding, we
have leveraged Sentence Transformer. Finally, we apply BART
and T5 models as Large Language Models to generate
multi-hop questions from our proposed model. Using HotpotQA
dataset to evaluate the performance of our KG4QG framework,
our proposed methodology has shown an enhancement of
performance over the previous methodologies.

Federated Graph Learning enables multiple clients to
collaboratively train graph models while protecting local
private data. However, most studies have assumed that all
clients contribute data voluntarily and actively. Without
reasonable incentives, clients are often reluctant to
contribute personal data for model training. Furthermore,
the budget for incentives is limited, and if clients with
low-quality graph data are incentivized to participate in
training, it will negatively impact the training
performance of all parties in the system. To address this,
we propose AEFGL, a Reverse Auction and Value
Evaluation-Based Incentive Mechanism for Federated Graph
Learning. First, we design a reverse auction mechanism
combining graph structural attribute motifs with client
production value. Then, we propose a method for evaluating
client production value based on the comparison of the
client's expected reward and actual value. This mechanism
can incentivize clients with high-quality graph data to
participate in training within budget constraints, thereby
improving the model quality. Experimental results validate
the superiority of the AEFGL mechanism and the economic
properties it satisfies.

The two-dimensional (2D) graph structure of a molecule encodes abundant latent property information. A well-designed molecular graph encoder can capture informative low-dimensional dense representations of molecules, which can subsequently be applied to a widerange of downstream tasks. To achieve fine-grained anddiscriminative molecular representations that capture localized structural information, we propose an novel atom-level adaptive receptive field encoder, enabling each atomic node in the molecular graph to dynamically adjust its receptive field size. To the best of our knowledge, we are the first to introduce an effective rank-guided pruning
strategy for 2D molecular graphs.

Atom-level Adaptive Receptive Fields: A Pruning-Based Encoder for 2D Molecular Graphs (Student Abstract)

Integrating knowledge from scientific literature is essential in biomedical research. However, the rapid growth of scientific literature makes staying up to date increasingly challenging. Retrieval-Augmented Generation (RAG) offers a promising framework, but its effectiveness in specialized biomedical domains remains unclear. In this work, we propose a two-stage retrieval pipeline for RAG, with a focus on Bordetella pertussis as a case study. Our method first applies hard filtering with synonym expansion to eliminate irrelevant passages, and then performs hybrid search, followed by reranking. We evaluate our approach using a dataset of 58 pertussis-related queries with automatic relevance judgments from multiple large language models (LLMs). Experimental results show that our pipeline improves MAP@10 by 13.4-20.4 points compared with existing methods and achieves the highest MRR@10. Furthermore,
consistent improvements across different LLMs highlight the effectiveness of our approach.

Quantum batteries have emerged as a next-generation energy
storage solution, leveraging quantum phenomena such as
superabsorption to overcome the limitations of conventional
energy technologies.
However, noise arising from interactions with the external
environment degrades the charging efficiency and stability
of the battery by disrupting the system's quantum coherence.
To address this challenge, this study proposes a robust
charging framework for a single-qubit quantum battery based
on the Jaynes-Cummings (JC) model.
The proposed framework combines the Proximal Policy
Optimization (PPO) algorithm with a multi-stage
reinforcement learning structure.
The agent first learns fundamental control principles in a
noise-free, ideal environment and subsequently performs
robust learning in progressively noisier and more complex
settings.
Simulation results demonstrate that the trained agent
navigates a stable charging trajectory on the Bloch sphere,
thereby achieving high ergotropy even in the presence of
noise.
These findings suggest that multi-stage reinforcement
learning is an effective solution for control problems in
noisy quantum systems and provides a theoretical foundation
for designing charging protocols for multi-qubit systems.

What if the next generation of human-computer interaction
is not a screen... but a conversation? Large Language
Models (LLMs) offer a new paradigm for interacting with
computers through text, but they lack shape reasoning
capabilities. We introduce Textual Anatomy Encoding (TAE),
a workflow that connects LLMs with 3D anatomies. TAE
employs clinician-validated semantic annotations and
rule-based prompts to achieve deterministic and
interpretable landmark localization. The results indicate
that TAE enables LLMs to move beyond text knowledge,
achieving accurate anatomy shape understanding. This
framework opens opportunities for diagnosis, surgical
planning, and scalable medical annotation, positioning LLMs
as a foundation for next-generation human–computer
interaction in healthcare.

Can Large Language Models Grasp 3D Medical Anatomy Shapes? (Student Abstract)

Radiotherapy (RT) is a cornerstone of cancer treatment, utilizing high doses of radiation to kill cancer cells and shrink tumors. Following RT, patient-reported outcomes (PROs) collected via standardized questionnaires are crucial for monitoring quality of life and side effects. However, traditional statistical and machine learning methods, which rely on structured numerical data, often fail to capture the nuanced emotions and semantic meaning within patients' health status. To address this, we developed a novel framework using zero- and few-shot Large Language Models (LLMs) to identify patients experiencing mild to severe depression. Furthermore, we enhanced classification performance through parameter-efficient fine-tuning with Low-Rank Adaptation (LoRA). The key is to freeze the pre-trained model's weights and add trainable low-rank matrices to each Transformer layer, drastically reducing the number of parameters in few-shot LLMs that need to be trained. Experiments on a prostate cancer PRO dataset for depression demonstrated that our fine-tuned LLMs consistently outperformed other baseline methods across key metrics, including AUC, AUCPR, Precision, and F1-score.

Fine-tuning Zero-shot Large Language Models for Patient-reported Outcomes (Student Abstract)

Large language models (LLMs) often perform better when
prompted to explain their reasoning, but it remains unclear
how well such gains persist as reasoning depth increases.
In this work, we propose a depth-aware evaluation framework
alongside the performance results on two structured
datasets: CLUTRR (kinship reasoning) and ProofWriter
(logical entailment), comparing direct vs. reasoning
(reasoning depth = number of inference steps required)
prompts across five models. Reasoning gave small gains at
shallow depths but quickly weakened and often reversed as
tasks grew more complex. In ProofWriter, GPT-5 reached 90%
accuracy at depth four in direct model, yet its reasoning
accuracy fell below baseline after depth two. Smaller
open-source models showed only unstable or negligible
gains, underscoring that reasoning in LLMs remains brittle
with increased depth.
