The paradoxical nature of easily improvable evidence
Maria Chikina, Wesley Pegden
Established frameworks to understand problems with reproducibility in science begin with the relationship between our understanding of the prior probability of a claim and the stat…
A note on sampling biases in the Bangladesh mask trial
Maria Chikina, Wesley Pegden, Benjamin Recht
A recent cluster trial in Bangladesh randomized 600 villages into 300 treatment/control pairs, to evaluate the impact of an intervention to increase mask-wearing. Data was analyzed…
Failure of monotonicity in epidemic models
Maria Chikina, Wesley Pegden
We discuss the failure of monotonicity properties for even simple compartmental epidemic models, for the case where transmission rates are non-constant. We also identify a special…
Modeling strict age-targeted mitigation strategies for COVID-19
Maria Chikina, Wesley Pegden
We use a simple SIR-like epidemic model which integrates known age-contact patterns for the United States to model the effect of age-targeted mitigation strategies for a COVID-19-l…
Separating effect from significance in Markov chain tests
Maria Chikina, Alan Frieze, Jonathan Mattingly +1
We give qualitative and quantitative improvements to theorems which enable significance testing in Markov Chains, with a particular eye toward the goal of enabling strong, interpre…
Phase Conductor on Multi-layered Attentions for Machine Comprehension
Rui Liu, Wei Wei, Weiguang Mao +1
Attention models have been intensively studied to improve NLP tasks such as machine comprehension via both question-aware passage attention model and self-matching attention model.…
An analysis of the Act 43 Wisconsin Assembly district map using the test
Maria Chikina, Alan Frieze, Wesley Pegden
In previous work [arXiv:1608.02014], we developed a rigorous statistical test for outlier status in a reversible Markov Chain, and demonstrated its utilization with an application…
Assessing significance in a Markov chain without mixing
Maria Chikina, Alan Frieze, Wesley Pegden
We present a new statistical test to detect that a presented state of a reversible Markov chain was not chosen from a stationary distribution. In particular, given a value function…
