adaption_math_word_problem_sub_2

Model Training

A LORA adapter for meta-llama/Llama-3.2-3B-Instruct. This model was trained with SFT using Adaption's AutoScientist on the math_word_problem_sub_2 dataset.

Model Details

• Base model: meta-llama/Llama-3.2-3B-Instruct
• Training method: SFT + LoRA
• LoRA rank: 16 | alpha: 32
• Epochs: 3
• Learning rate: 1e-5 (cosine schedule)
• Trainable modules: all-linear
• Data format: chat

Training Data

The model was trained on 19,573 rows of adapted data with the following domain distribution: math (99%), language (0%), science (0%), personal-finance (0%), fitness-sports (0%), animal-nature (0%), agriculture (0%), how-to (0%), sports (0%), travel (0%), data-analysis-visualization (0%).

Trained on the adapted dataset:
→ Minutor/adaption-math-word-problem-sub-2

Which itself was derived from the cleaned seed:
→ Minutor/20k_math_dataset
(GSM8K + NuminaMath-1.5 + OpenMathInstruct-1)

Evaluation Results

Win rates are computed by Adaption using Gemini 3.1 Pro as the judge.

Evaluation	Sample size	Base	Adapted	Change
Win-rate on training distribution	200 held-out datapoints	42	58	+16
Math Win-rate (Adaption held-out)	100 unseen datapoints across Math tasks	51	50	–1

The model shows a clear +16 point improvement on its training distribution while remaining essentially neutral on Adaption’s broader Math evaluation set.
