**To use MathT5 easily:**

1. Download  ```MathT5.py```  to your working directory.
2. ```from MathT5 import load_model, inference```
3. ```tokenizer, model = load_model("jmeadows17/MathT5-large")```
4. ```inference(prompt, tokenizer, model)```

```MathT5.pretty_print(text, prompt=True)``` makes prompts and outputs (```prompt=False```) easier to read.

**Overview**

MathT5-large is a version of FLAN-T5-large fine-tuned for 25 epochs on 15K (LaTeX) synthetic mathematical derivations (containing 4 - 10 equations), that were generated using a symbolic solver (SymPy).
It outperforms GPT-4 and ChatGPT on a derivation generation task in ROUGE, BLEU, BLEURT, and GLEU scores, and shows some generalisation capabilities.
It was trained on 155 physics symbols, but struggles with out-of-vocabulary symbols. Paper available soon.


**Example prompt:**

```prompt = "Given \\cos{(q)} = \\theta{(q)},
then derive - \\sin{(q)} = \\frac{d}{d q} \\theta{(q)},
then obtain (- \\sin{(q)})^{q} (\\frac{d}{d q} \\cos{(q)})^{q} = (- \\sin{(q)})^{2 q}"```

Output derivations are equations separated by "and".

Use ```"jmeadows17/MathT5-base"``` for the lightweight version.
