Paper Accepted at ICLR 2025 (Spotlight): When do GFlowNets Learn the Right Distribution?

·256 words

I am delighted to announce that our paper, When do GFlowNets Learn the Right Distribution?, has been accepted for presentation at ICLR 2025! This work advances our theoretical understanding of Generative Flow Networks (GFlowNets) by examining the impact of balance violations on their ability to approximate target distributions and proposing a novel metric for assessing correctness.

(old post, test) Sampling from Dirichlet Distribution using Gamma Distributed Samples

·562 words

There is an algorithm to generate Dirichlet samples using a sampler for Gamma distribution for any \( \alpha > 0 \) and \( \beta > 0 \). We will generate Gamma distributed variables \( z_k \sim \text{gamma}(\alpha_k,1) \), for \( k \in {1,\cdots,d} \), and do the following variable transformation to get Dirichlet samples \( x_k = \frac{z_k}{\sum_k z_k} \). First, we should demonstrate that this transformation results in Dirichlet distributed samples.
