# Diffusion Generative Flow Samplers 

[Diffusion Generative Flow Samplers (DGFS):

Improving learning signals through partial trajectory optimization](https://arxiv.org/abs/2310.02679)

[Dinghuai Zhang](https://zdhnarsil.github.io/), 

[Ricky Tian Qi Chen](https://rtqichen.github.io//),

Aaron Courville, 

[Yoshua Bengio](https://yoshuabengio.org/).

We propose a novel DGFS sampler for continuous space sampling 

from given unnormalized densities based on stochastic optimal control 🤖 formulation

and the probabilistic 🎲 GFlowNet framework.



`target/` has the target distribution code.

`gflownet/` contains the DGFS algorithm code.

## Examples

```bash

python -m gflownet.main target=gm dt=0.05

python -m gflownet.main target=funnel

python -m gflownet.main target=wells

```

## Dependency

Apart from commonly used torch, torchvision, numpy, scipy, matplotlib,

we use the following packages:

```bash

pip install hydra-core omegaconf submitit hydra-submitit-launcher

pip install wandb tqdm einops seaborn ipdb

```
