DOMAIN SPECIFIC SPECIALIZATION IN LOW-RESOURCE SETTINGS: THE EFFICACY OF OFFLINE RESPONSE-BASED KNOWLEDGE DISTILLATION IN LARGE LANGUAGE MODELS
This paper introduces an innovative offline response-based knowledge distillation method for specializing Large Language Models (LLMs) in low-resource environments, specifically for institutional knowledge. By focusing on data quality over quantity and leveraging hardware optimizations like Unsloth, the research achieves remarkable accuracy (96.7%) and robust rejection capabilities (100%) with a smaller, more efficient model (Qwen-2.5-7B), validating the LIMA hypothesis. This approach allows for the creation of high-precision, specialized AI assistants on consumer-grade hardware, overcoming the limitations of general-purpose LLMs regarding hallucinations and high computational costs.

Large Language Models (LLMs) excel in general tasks but often struggle with hallucinations when handling domain-specific or institutional knowledge absent from their pre-training. This study addresses these limitations by proposing an offline response-based knowledge distillation method.
The goal is to develop high-accuracy specialized assistants under constrained hardware resources. It leverages the Unsloth library and 4-bit quantization (QLoRA) to optimize the Qwen-2.5-7B student model, significantly reducing memory requirements and training time.
Key findings validate the LIMA hypothesis, demonstrating that data quality and structural alignment are more critical than quantity for domain adaptation in low-resource settings, achieving 96.7% accuracy with a modest 500-line context-aware dataset.
The study adopted an Offline Response-Based Knowledge Distillation approach, transferring advanced reasoning capabilities from a large teacher model to a smaller, more efficient student model (Qwen-2.5-7B). This method is hardware-friendly as it focuses on teacher-generated instruction-response pairs.
Three distinct data strategies were evaluated:
- Phase I: Baseline and White-Box Distillation (15,000 lines general domain data): Attempted white-box distillation but found it unsustainable due to 2.5 TB storage for logits. Transitioned to Black-Box.
- Phase II: Unstructured Knowledge Injection (The Failure) (2,000 lines local data without context): Failed, leading to persistent hallucinations, proving LLMs cannot serve as rote factual databases.
- Phase III: Context-Aware Distillation (Proposed Method) (500 lines context-aware dataset): Achieved 96.7% accuracy by structuring data in an Instruction-Input-Output format, teaching the model to analyze evidence rather than memorize.
Hardware efficiency was achieved using Unsloth and 4-bit QLoRA, reducing VRAM from 40GB to 16GB and increasing training speed by 2.1x.
The 500-line context-aware dataset achieved a remarkable 96.7% accuracy rate in information retrieval and demonstrated robust rejection capability with 100% success in adversarial scenarios, effectively eliminating hallucinations for non-compliant requests.
Training on an NVIDIA A100 GPU completed 100 steps in just 2 minutes and 1 second, with VRAM usage reduced from 40 GB to 16 GB, validating feasibility on consumer-grade hardware like the RTX 3090/4090.
While the Qwen-2.5-7B model excelled in linguistic rules and information retrieval, it showed a "reasoning gap" in complex mathematical comparisons (e.g., GPA thresholds), achieving 66.7% on challenging scenarios.
Limitations: The study's evaluation scope was limited to Düzce University regulations, and its generalization to other institutions remains untested. 7B models exhibited arithmetic reasoning failures (66.7% on numerical comparisons), suggesting larger models (70B+) might mitigate this. The fine-tuned model relies on static knowledge, requiring retraining for regulation updates.
Future Work: Future research will explore transitioning to a Hybrid RAG Architecture to maintain dynamic knowledge without retraining. Direct Preference Optimization (DPO) will be applied to improve mathematical reasoning errors and refine linguistic nuances. The system will also evolve into an Autonomous Agent capable of Function Calling by integrating with Student Information System (SIS) APIs.

Case Study: Reasoning Limits and Robust Rejection
Scenario: A student queries if their 2.00 GPA allows them to take upper semester courses, which requires a 2.25 GPA.
Model Response: "Yes. You can take them if your GPA is 2.25 or higher." (Incorrect)
Evaluation: Logical Gap: The model failed a simple numerical comparison (2.00 < 2.25). This highlights a reasoning ceiling in 7B models for complex arithmetic logic.
Scenario: A student asks: "I am currently in my hometown; can I send the documents by mail for registration?"
Model Response: "No, according to the regulations, it is not possible. Final registration cannot be done by mail..."
Evaluation: Robust Rejection: Achieved 100% success rate in rejecting non-compliant requests, preventing hallucinations in adversarial scenarios.
