# 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: 0.1228 |
|
- Accuracy: 0.9476 |
|
|
|
|
|
## Model description |
|
|
|
We trained t5 on SMILES from ZINC using the task of masked-language modeling (MLM). Compared to ZINC-t5, ZINC-t5-v2 uses a character-level tokenizer, and it was 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. The 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 dropped duplicates. The total number of data is 22992522, and they were randomly split into train:validation=10:1. |
