## Strassen Attention

Implementation of [Strassen attention](https://arxiv.org/abs/2501.19215), from Kozachinskiy et al. of [National Center of AI](https://cenia.cl/) in Chile 🇨🇱

## Install

```shell
$ pip install strassen-attention
```

## Usage

```python
import torch
from strassen_attention import strassen_attend

q = torch.randn(1, 8, 32, 16)
k = torch.randn(1, 8, 32, 16)
v = torch.randn(1, 8, 32, 16)

attended = strassen_attend(
    q,
    k,
    k.clone(),
    v,
    v.clone()
)

assert attended.shape == q.shape
```

For the multi-head attention module

```python
import torch
from strassen_attention.strassen_mha import StrassenMHA

mha = StrassenMHA(dim = 512, causal = True)

tokens = torch.randn(1, 256, 512)

assert mha(tokens).shape == tokens.shape
```

Strassen attention transformer

```python
import torch
import torch
from strassen_attention.strassen_transformer import StrassenTransformer

transformer = StrassenTransformer(dim = 512, depth = 4)

x = torch.randn(1, 16 * 16, 512)
assert transformer(x).shape == x.shape
```
