SmolLM2-MedIT-Upscale-2B

Model Summary

SmolLM2-MedIT-Upscale-2B is an expanded version of the SmolLM2-1.7B-Instruct model, increasing its parameter count to 2 billion. This expansion was achieved by doubling the number of heads in the q_proj, k_proj, v_proj, and o_proj layers, resulting in vectors of length 4096, compared to 2048 in the original model.

Purpose of Expansion

This model was developed to test the hypothesis that self-attention layers do not extend the "memory" of the model. By broadening the attention layers, we aim to observe the impact on the model's performance and memory capabilities.

Training Status

This model underwent instruction fine-tuning for 8,800 steps using a batch size of 4, gradient accumulation for 32 steps, a maximum sequence length of 1,280, and a learning rate of 1e-5. Additionally, it was fine-tuned with 1,600 steps of DPO under the same configuration.

Note: The model has undergone preliminary training focused on assessing the effects of the expanded attention layers. It is not fully trained to its maximum potential. We encourage the community to contribute to its further training; pull requests are welcome.

Analysis of Expanded Layers

During fine-tuning, we analyzed the changes in the new parameters of the expanded layers:

  • Minimum percentage of new parameters that changed:

    • q_proj: 62.17%
    • k_proj: 37.85%
    • v_proj: 99.99%
    • o_proj: 99.98%
  • Maximum percentage of new parameters that changed:

    • q_proj: 98.86%
    • k_proj: 97.99%
    • v_proj: 99.99%
    • o_proj: 99.99%
  • Average change in new parameters after fine-tuning:

    • q_proj: 1.838e-07
    • k_proj: 2.277e-07
    • v_proj: 6.490e-07
    • o_proj: 3.924e-07
