## Slot Attention

Implementation of Slot Attention from the paper 'Object-Centric Learning with Slot Attention' in Pytorch. Here is a video that describes what this network can do.

Update: The official repository has been released here

## Install

```bash
$ pip install slot_attention
```

## Usage

```python
import torch
from slot_attention import SlotAttention

slot_attn = SlotAttention(
num_slots = 5,
dim = 512,
iters = 3 # iterations of attention, defaults to 3
)

inputs = torch.randn(2, 1024, 512)
slot_attn(inputs) # (2, 5, 512)
```

After training, the network is reported to be able to generalize to slightly different number of slots (clusters). You can override the number of slots used by the `num_slots` keyword in forward.

```python
slot_attn(inputs, num_slots = 8) # (2, 8, 512)
```

To use the adaptive slot method for generating a differentiable one hot mask for whether to use a slot, just do the following

```python
import torch
from slot_attention import MultiHeadSlotAttention, AdaptiveSlotWrapper

# define slot attention

slot_attn = MultiHeadSlotAttention(
dim = 512,
num_slots = 5,
iters = 3,
)

# wrap the slot attention

adaptive_slots = AdaptiveSlotWrapper(
slot_attn,
temperature = 0.5 # gumbel softmax temperature
)

inputs = torch.randn(2, 1024, 512)

slots, keep_slots = adaptive_slots(inputs) # (2, 5, 512), (2, 5)

# the auxiliary loss in the paper for minimizing number of slots used for a scene would simply be

keep_aux_loss = keep_slots.sum() # add this to your main loss with some weight
```
