Cousins Of The Vendi Score: A Family Of Similarity-Based Diversity Metrics For Science And Machine Learning

2 code implementations19 Oct 2023 Amey P. Pasarkar, Adji Bousso Dieng

Contrary to many diversity metrics in ecology, the Vendi Score accounts for similarity and does not require knowledge of the prevalence of the categories in the collection to be evaluated for diversity.

The Vendi Score: A Diversity Evaluation Metric for Machine Learning

1 code implementation5 Oct 2022 Dan Friedman, Adji Bousso Dieng

Importantly, unlike many existing metrics in ML, the Vendi Score does not require a reference dataset or distribution over samples or labels, it is therefore general and applicable to any generative model, decoding algorithm, and dataset from any domain where similarity can be defined.

Markov Chain Score Ascent: A Unifying Framework of Variational Inference with Markovian Gradients

1 code implementation13 Jun 2022 Kyurae Kim, Jisu Oh, Jacob R. Gardner, Adji Bousso Dieng, HongSeok Kim

Minimizing the inclusive Kullback-Leibler (KL) divergence with stochastic gradient descent (SGD) is challenging since its gradient is defined as an integral over the posterior.

Variational Inference via \chi Upper Bound Minimization

no code implementations NeurIPS 2017 Adji Bousso Dieng, Dustin Tran, Rajesh Ranganath, John Paisley, David Blei

In this paper we propose CHIVI, a black-box variational inference algorithm that minimizes $D_{\chi}(p || q)$, the $\chi$-divergence from $p$ to $q$.
