Appendix
We used the next hyperparameters as a part of our fine-tuning:
- Studying fee multiplier – Learning rate multiplier is without doubt one of the most crucial hyperparameters in LLM fine-tuning. It influences the training fee at which mannequin parameters are up to date after every batch.
- Batch dimension – Batch size is the variety of coaching examples processed in a single iteration. It instantly impacts GPU reminiscence consumption and coaching dynamics.
- Epoch – One epoch means the mannequin has seen each instance within the dataset one time. The variety of epochs is a vital hyperparameter that impacts mannequin efficiency and coaching effectivity.
For our analysis, we used the F1 rating, which is an analysis metric to evaluate the efficiency of LLMs and conventional ML fashions.
To compute the F1 rating for LLM analysis, we have to outline precision and recall on the token stage. Precision measures the proportion of generated tokens that match the reference tokens, and recall measures the proportion of reference tokens which might be captured by the generated tokens. The F1 rating ranges from 0–100, with 100 being the absolute best rating and 0 being the bottom. Nevertheless, interpretation can differ relying on the particular job and necessities.
We calculate these metrics as follows:
- Precision = (Variety of matching tokens in generated textual content) / (Complete variety of tokens in generated textual content)
- Recall = (Variety of matching tokens in generated textual content) / (Complete variety of tokens in reference textual content)
- F1 = (2 * (Precision * Recall) / (Precision + Recall)) * 100
For instance, let’s say the LLM generates the sentence “The cat sits on the mat within the solar” and the reference sentence is “The cat sits on the mushy mat below the nice and cozy solar.” The precision could be 6/9 (6 matching tokens out of 9 generated tokens), and the recall could be 6/11 (6 matching tokens out of 11 reference tokens).
- Precision = 6/9 ≈ 0.667
- Recall = 6/11 ≈ 0.545
- F1 rating = (2 * (0.667 * 0.545) / (0.667 + 0.545)) * 100 ≈ 59.90
