## 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
