Qwen2.5-0.5B-linear-merge
🧬 Research Artifact from the Lemuru Autonomous AI Research System
Hypothesis-driven model fusion exploring the synergistic effects of instruction-tuned and base language model capabilities in text generation.
Research Overview
This model represents a systematic exploration of enhanced text generation capabilities through controlled model merging. Created by our autonomous research agent as part of hypothesis HYP-001, this fusion investigates whether combining the instruction-following capabilities of Qwen2.5-0.5B-Instruct with the foundational strengths of Qwen2.5-0.5B yields synergistic improvements in generating coherent and contextually relevant text.
Research Hypothesis: The linear combination of instruction-tuned and base language models will result in improved performance in text generation tasks, particularly in instruction adherence and contextual understanding.
Methodology: Linear fusion of model weights with a 60-40 parameter strategy, optimizing for enhanced instruction-following and contextual coherence.
