The rapid advancement of large language models (LLMs) has revolutionized natural language processing (NLP), enabling unprecedented capabilities in text generation, comprehension, and application. However, despite their remarkable performance in diverse tasks, a significant gap remains in their ability to exhibit consistent and robust logical reasoning. This research paper proposes a comprehensive framework for the post-training evaluation and enhancement of logical reasoning capabilities in advanced LLMs. The framework employs scenario-based logic challenges and reasoning puzzles designed to identify and address logical inconsistencies in model outputs. By leveraging a structured feedback-driven refinement strategy, the framework iteratively evaluates and improves the logical coherence and reasoning accuracy of the models.
Central to this study is the development of modular evaluation protocols that utilize tools such as Hugging Face libraries to quantify reasoning performance across multiple dimensions, including deductive reasoning, inductive reasoning, and the ability to resolve ambiguous or conflicting scenarios. These protocols emphasize real-world applicability by introducing task-specific logical challenges inspired by domains such as legal reasoning, scientific inquiry, and ethical decision-making. Furthermore, this paper presents methodologies for diagnosing reasoning errors, such as flawed premise recognition, circular logic, and overgeneralization, which are prevalent in LLM outputs.
To enhance reasoning capabilities, the feedback-driven refinement process integrates adversarial retraining and reinforcement learning-based fine-tuning methods, supported by curated datasets specifically designed to target logical inadequacies. The iterative nature of this approach ensures continuous improvement while preserving the general linguistic proficiency of the models. The proposed framework is experimentally validated using state-of-the-art LLMs, including models with billions of parameters, demonstrating measurable improvements in reasoning metrics across diverse benchmarks.
This research contributes to the broader field of NLP by addressing a critical limitation of LLMs, thereby enhancing their applicability in high-stakes domains where logical consistency is paramount. The findings underscore the importance of post-training interventions and pave the way for future research in reasoning-specific model architectures, evaluation techniques, and ethical considerations associated with logical inference in artificial intelligence systems.
