Gender gaps in frontier entrepreneurship? Evidence from 1901 Oklahoma land lottery winners

1 code implementation29 Jun 2022 Jason Poulos

For a sample of winners linked to the 1910 Census, I find that male winners have higher median dose-responses compared to female winners in terms of farm or home ownership.

Are deep learning models superior for missing data imputation in large surveys? Evidence from an empirical comparison

1 code implementation14 Mar 2021 Zhenhua Wang, Olanrewaju Akande, Jason Poulos, Fan Li

We conduct extensive simulation studies based on a subsample of the American Community Survey to compare the repeated sampling properties of four machine learning based MI methods: MICE with classification trees, MICE with random forests, generative adversarial imputation networks, and multiple imputation using denoising autoencoders.

Adversarial Machine Learning: Bayesian Perspectives

1 code implementation7 Mar 2020 David Rios Insua, Roi Naveiro, Victor Gallego, Jason Poulos

Adversarial Machine Learning (AML) is emerging as a major field aimed at protecting machine learning (ML) systems against security threats: in certain scenarios there may be adversaries that actively manipulate input data to fool learning systems.

Character-Based Handwritten Text Transcription with Attention Networks

1 code implementation11 Dec 2017 Jason Poulos, Rafael Valle

When the sequence alignment is one-to-one, softmax attention is able to learn a more precise alignment at each step of the decoding, whereas the alignment generated by sigmoid attention is much less precise.
