svd_franken_merge1

This is a merge of pre-trained language models created using mergekit.

Merge Details

Merge Method

This model was merged using the svd_franken_merge merge method using meta-llama/Llama-2-7b-chat-hf as a base.

Configuration

The following YAML configuration was used to produce this model:

models:
  - model: allenai/tulu-2-dpo-7b
    parameters:
      weight: 1.0
  # - model: EleutherAI/llemma_7b
  #   parameters:
  #     weight: 1.0
merge_method: svd_franken_merge
base_model: meta-llama/Llama-2-7b-chat-hf
parameters:
  probabilistic: True # use probabilistic SVD algorithm (maybe fastest but little inaccurate) instead of the non probabilistic SVD algorithm (slowest but accurate)
  sv_reduction: 1.0 # strict value: "1.0 / number of task vector" if number of task vector is >=2 (percentage of singular components to keep for each TV)
  sv_scaling: 1.0 # float (hyperparameter): suggested nearby "number of task vector / 2.0" if number of task vector is >=2 else 1.0 (reduction to the stretching factor of the singular values)
  num_iterations: 4 # number of iterations for the probabilistic SVD algorithm (2 is a good start and fastest option but could be inaccurate, 32 is the most accurate but slowest option. I don't recommend going above 32 use SVD probabilistic at False instead)
