## Adam-atan2 - Pytorch
Implementation of the proposed <a href="https://arxiv.org/abs/2407.05872">Adam-atan2</a> optimizer in Pytorch
A multi-million dollar paper out of google deepmind proposes a small change to Adam update rule (using `atan2`) to remove the epsilon altogether for numerical stability and scale invariance
## Install
```bash
$ pip install adam-atan2-pytorch
```
## Usage
```python
import torch
from torch import nn
# toy model
model = nn.Linear(10, 1)
# import AdamAtan2 and instantiate with parameters
from adam_atan2_pytorch import AdamAtan2
opt = AdamAtan2(model.parameters(), lr = 1e-4)
# forward and backwards
for _ in range(100):
loss = model(torch.randn(10))
loss.backward()
# optimizer step
opt.step()
opt.zero_grad()
```
