| 2025 | Quantum-Amplitude Embedded Adaptation for Parameter-Efficient Fine-Tuning in Large Language ModelsabstractLarge language models (LLMs) require substantial resources for task-specific adaptation, that motivates the development of parameter-efficient fine-tuning (PEFT) methods. This paper presents quantum-amplitude embedded adaptation (QAA), a novel PEFT framework that logarithmically compresses activation vectors using quantum-amplitude embedding and applies expressive non-linear transformations via parameterized quantum circuits (PQCs). By replacing linear adapters in attention modules with compact quantum modules, QAA achieves high expressivity while drastically reducing the number of trainable parameters. Empirical results demonstrate that QAA performs on par with or better than existing PEFT under constrained memory and compute budgets, highlighting its potential for efficient LLM fine-tuning.

| 2025 | LLM-based Interactive Coding Education via Predictive Query Management and Student-Centered Fine-Tuning: Design and Implementation with 1500-Student Class DataabstractLarge-scale university courses face significant challenges. Teaching assistants are overwhelmed by the large number of student questions, limiting their ability to provide detailed and individualized support. As a result, students-especially those who are struggling-receive less tailored assistance, further widening gaps in academic performance. To address these challenges, we propose student-centered AI learning assistant (SCALA), a large language model (LLM)-based interactive tutoring system that incorporates student needs and learning expectations. SCALA consists of two main components, i.e., predictive query management and student-centered fine tuning. The first component anticipates common student questions via LLM agent debate. Each agent interacts using a combination of lecture content and student interactions in chat logs, collaboratively predicting what the students will likely ask. This fosters learning in students by generating and presenting relevant queries that guide their learning. On the other hand, the second component is fine-tuned on a 14k-question Python-tutoring dataset, curated based on in-depth student interviews to reflect real learning expectations. Our real-world experiments with 1500-student large-scale Python classes demonstrate that SCALA delivers more helpful and accurate responses compared to closed-form models (e.g., GPT-4o), while significantly reducing latency.

| 2024 | Hands-On Introduction to Quantum Machine LearningabstractThis tutorial offers a hands-on introduction into the captivating field of quantum machine learning (QML). Beginning with the bedrock of quantum information science (QIS)-including essential elements like qubits, single and multiple qubit gates, measurements, and entanglement-the session swiftly progresses to foundational QML concepts. Participants will explore parameterized or variational circuits, data encoding or embedding techniques, and quantum circuit design principles. Delving deeper, attendees will examine various QML models, including the quantum support vector machine (QSVM), quantum feed-forward neural network (QNN), and quantum convolutional neural network (QCNN). Pushing boundaries, the tutorial delves into cutting-edge QML models such as quantum recurrent neural networks (QRNN) and quantum reinforcement learning (QRL), alongside privacy-preserving techniques like quantum federated machine learning, bolstered by concrete programming examples. Throughout the tutorial, all topics and concepts are brought to life through practical demonstrations executed on a quantum computer simulator. Designed with novices in mind, the content caters to those eager to embark on their journey into QML. Attendees will also receive guidance on further reading materials, as well as software packages and frameworks to explore beyond the session. Samuel Yen-Chi Chen, Joongheon Kim |

| 2023 | Logarithmic Dimension Reduction for Quantum Neural NetworksabstractIn recent years, quantum neural network (QNN) based on quantum computing has attracted attention due to its potential for computation-acceleration and parallelism. However, the intrinsic limitations of QNN, where the output (i.e., observables) can only be obtained through a measurement process, pose scalability challenges. Motivated by this, this paper aims to address the scalability challenges by incorporating Pauli-Z measurement and Basis measurement. In conventional frameworks, QNN typically relies on classical fully connected networks (FCNs) or increases the number of qubits to achieve large output dimensions. However, by leveraging our proposed framework, this paper successfully expands the output dimensions to an exponential scale, surpassing the limitations imposed by the limited number of qubits without relying on FCNs. Through extensive experiments, this paper demonstrates that the proposed framework outperforms existing QNN frameworks in multi-class classification tasks that require numerous output dimensions.

| 2023 | Quantum Split Learning for Privacy-Preserving Information ManagementabstractRecently, research on quantum neural network (QNN) architectures has been attracted in various fields. Among them, the distributed computation of QNN has been actively discussed for privacy-preserving information management due to data and model distribution over multiple computing devices. Based on this concept, this paper proposes quantum split learning (QSL) which splits a single QNN architecture across multiple distributed computing devices to avoid entire QNN architecture exposure. In order to realize QSL design, this paper also proposes cross-channel pooling, which utilizes quantum state tomography. Our evaluation results verifies that QSL preserves privacy in classification tasks and also improves accuracy at most by 6.83% compared to existing methods.

| 2022 | Hierarchical Reinforcement Learning using Gaussian Random Trajectory Generation in Autonomous Furniture AssemblyabstractIn this paper, we propose a Gaussian Random Trajectory guided Hierarchical Reinforcement Learning (GRT-HL) method for autonomous furniture assembly. The furniture assembly problem is formulated as a comprehensive human-like long-horizon manipulation task that requires a long-term planning and a sophisticated control. Our proposed model, GRT-HL, draws inspirations from the semi-supervised adversarial autoencoders, and learns latent representations of the position trajectories of the end-effector. The high-level policy generates an optimal trajectory for furniture assembly, considering the structural limitations of the robotic agents. Given the trajectory drawn from the high-level policy, the low-level policy makes a plan and controls the end-effector. We first evaluate the performance of GRT-HL compared to the state-of-the-art reinforcement learning methods in furniture assembly tasks. We demonstrate that GRT-HL successfully solves the long-horizon problem with extremely sparse rewards by generating the trajectory for planning.
