# ZINC-t5 

This model is a fine-tuned version of [google/t5-v1_1-base](https://huggingface.co./microsoft/deberta-base) on the sagawa/ZINC-canonicalized dataset.
It achieves the following results on the evaluation set:
- Loss: 0.1202
- Accuracy: 0.9497


## Model description

We trained t5 on SMILES from ZINC using the task of masked-language modeling (MLM). Its tokenizer is also trained on ZINC.


## Intended uses & limitations

This model can be used for the prediction of molecules' properties, reactions, or interactions with proteins by changing the way of finetuning.
As an example, We finetuned this model to predict products. Model is [here](https://huggingface.co./sagawa/ZINC-t5-productpredicition), and you can use the demo [here](https://huggingface.co./spaces/sagawa/predictproduct-t5).
Using its encoder, we trained a regression model to predict a reaction yield. You can use this demo [here](https://huggingface.co./spaces/sagawa/predictyield-t5).

## Training and evaluation data

We downloaded [ZINC data](https://drive.google.com/drive/folders/1lSPCqh31zxTVEhuiPde7W3rZG8kPgp-z) and canonicalized them using RDKit. Then, we droped duplicates. The total number of data is 22992522, and they were randomly split into train:validation=10:1.

## Training procedure

### Training hyperparameters
