Model Description
Model created by analyzing and selecting the optimal layers from other Qwen2.5-7B models based on their dimensional utilization efficiency, measured by the Normalized Effective Rank (NER). Computed like:
- Input: Weight matrix for each model layer
- Compute singular values σᵢ where σᵢ ≥ 0 # σᵢ represents the importance of each dimension
- Filter values above numerical threshold (>1e-12)
- Sum all singular values: S = Σσᵢ # S acts as normalization factor
- Create probability distribution: pᵢ = σᵢ/S # converts singular values to probabilities summing to 1
- Compute Shannon entropy: H = -Σ(pᵢ * log₂(pᵢ)) # measures information content
- Calculate maximum possible entropy: H_max = log₂(n)
- Final NER score = H/H_max # normalizes score to [0,1] range
- Results in value between 0 and 1 for each model layer
Creating Composite Model
Code here: https://huggingface.co/jeffmeloy/Qwen2.5-7B-nerd-uncensored-v1.0/blob/main/ner_merge.py
Code functions:
- Download selected models from Hugging Face Hub
- Calculate Normalized Effective Rank (NER) for each layer within each model
- Define model and layer name pairs that have highest NER for each layer based on their NER scores
- Incrementally build a composite model using layer with highest NER from model pool
- Save merge reports documenting layer sources
- Copy config and tokenizer files from base model
- Save the composite model with complete weights # model ready to use
