/ The topic model and the RNN parameters are learned jointly using amortized variational inference. Augment and Reduce: Stochastic Inference for Large Categorical Distributions. Poster Dieng was also the second black woman to graduate from the department of Statistics at Columbia University. To fit the model we leverage moment matching to learn rich proposals to estimate the EM objective. This AI Expert From Senegal Is Helping Showcase Africans In STEM. Sort by citations Sort by year Sort by title. Adji Bousso Dieng wants to give young Africans the inspiring examples she missed out on. arxiv This two-step procedure shies away from the current VAE approach of bundling together model fitting and posterior inference. International Conference on Artificial Intelligence and Statistics (AISTATS), 2019 However minimizing the KL leads to approximations that underestimate posterior uncertainty. Transactions of the Association for Computational Linguistics (TACL), 2020, A. David M. Blei In this episode, i’m joined by Adji Bousso Dieng, PhD Student in the Department of Statistics at Columbia University. Dieng is supported by a Dean Fellowship from Columbia University. New website by Senegalese AI expert spotlights Africans in STEM. Cited by. / David M. Blei She is currently an Artificial Intelligence Research Scientist at Google Brain in Mountain View, California. Slides. Francisco R. J. Ruiz*, [4], Dieng has authored/co-authored several papers published in AI venues such as NeurIPS, ICML, ICLR, AISTATS, and TACL. Avoiding Latent Variable Collapse With Generative Skip Models. Dieng is supported by a Dean Fellowship from Columbia University. Code International Conference on learning Representation (ICLR), 2017, A. Neural Information Processing Systems (NeurIPS), 2017 Adji Bousso Dieng, Dustin Tran, Rajesh Ranganath, John Paisley, David Blei Abstract Variational inference (VI) is widely used as an efficient alternative to Markov chain Monte Carlo. [6] Prior to her work at Google, Dieng interned at many major companies in AI such as Microsoft Research in Seattle, DeepMind in London, and she also worked with Yann LeCun at Facebook AI Research. at Columbia University where I am jointly being advised by David Blei Jianfeng Gao, International Conference on Machine Learning (ICML), 2018 [2] Her father never attended school, and her mother started but did not complete high school. /. My second goal is to develop efficient, scalable, and generic algorithms for learning with these models. img. CV  /  [2] She won one of the prizes for the Senegalese Olympiad ("Concours Général") in Philosophy, was selected to participate in the 2005 Excellence camp organized by the Pathfinder Foundation for Education and Development, a non-profit founded by Cheick Modibo Diarra, and was subsequently selected to participate in a competitive exam organized for African girls in partnership between the Central Bank for West African States and the Pathfinder Foundation. Noisin is an explicit regularizer--it's objective function can be decomposed as the original objective for the deterministic RNN and a non-negative data-dependent term. Maja Rudolph, Topic Modeling in Embedding Spaces / Dustin Tran, International Conference on Machine Learning (ICML), 2018, A. David M. Blei An extension of the Embedded Topic Model to corpora with temporal dependencies. Adji B. Dieng, Under Review at Journal of Machine Learning Research (JMLR). The criterion for learning is a divergence measure. This solution leads to the Skip-VAE--a deep generative model that avoids latent variable collapse. Adji Bousso Dieng will be Princeton's School of Engineering's first Black female faculty. International Conference on Machine Learning (ICML), 2018 The most used divergence is the Kullback-Leibler (KL) divergence. However minimizing the KL leads to approximations that underestimate posterior uncertainty. September 16, 2020 September 15, 2020 The African Mirror Adji Bousso Dieng, artificial intelligence, Senegalese AI expert. [9] Dieng noticed the inaccurate portrayal of Africa in the media, which was further accentuated during the COVID-19 global crisis. Come next September, Adji Bousso Dieng — an expert in artificial intelligence and machine learning — will join the faculty of the School of Engineering and Applied Science (SEAS) as a tenure-track assistant professor, becoming the first Black female faculty member in the history of SEAS and the first Black faculty member ever in the Department of Computer Science (COS).
