Statistical models on full and partial rankings of n items are often of limited practical use for large n due to computational consideration. We explore the use of non-parametric models for partially...
Inflationary Potential from 21 cm Tomography and Planck (2008)
Barger, Vernon, Gao, Yu, Mao, Yi, Marfatia, Danny
Three-dimensional neutral hydrogen mapping using the redshifted 21 cm line has recently emerged as a promising cosmological probe. Within the framework of slow-roll reconstruction, we analyze how...
Constraining Gravitational and Cosmological Parameters with Astrophysical Data (2008)
We use astrophysical data to shed light on fundamental physics by constraining parametrized theoretical cosmological and gravitational models. Gravitational parameters are those constants that...

Sequential Models for Sentiment Prediction (2008)
We examine the problem of predicting local sentiment flow in documents, and its application to several areas of text analysis. Formally, the problem is stated as predicting an ordinal sequence based...

The Locally Weighted Bag of Words Framework for Document Representation (2008)
Guy Lebanon, Yi Mao, Joshua Dillon
The popular bag of words assumption represents a document as a histogram of word occurrences. While computationally efficient, such a representation is unable to maintain any sequential information....

High dimensional structured data such as text and images is often poorly understood and misrepresented in statistical modeling. The standard histogram representation suffers from high variance and...
Sequential document visualization (2008)
Yi Mao, Joshua V. Dillon, Guy Lebanon
Abstract — Documents and other categorical valued time series are often characterized by the frequencies of short range sequential patterns such as n-grams. This representation converts sequential...
How accurately can 21 cm tomography constrain cosmology? (2008)
Mao, Yi, Tegmark, Max, McQuinn, Matthew, Zaldarriaga, Matias, Zahn, Oliver
There is growing interest in using 3-dimensional neutral hydrogen mapping with the redshifted 21 cm line as a cosmological probe, as it has been argued to have a greater long-term potential than the...

Constraining f(R) Gravity as a Scalar Tensor Theory (2006)
Faulkner, Thomas, Tegmark, Max, Bunn, Emory F., Mao, Yi
We search for viable f(R) theories of gravity, making use of the equivalence between such theories and scalar-tensor gravity. We find that models can be made consistent with solar system constraints...
Constraining Torsion with Gravity Probe B (2006)
Mao, Yi, Tegmark, Max, Guth, Alan, Cabi, Serkan
It is well-entrenched folklore that torsion gravity theories predict observationally negligible torsion in the solar system, since torsion (if it exists) couples only to the intrinsic spin of...
Signal dependent noise and its role in motor planning / (2006)
A thesis submitted to the Faculty of Graduate Studies and Research in partial fulfillment of the requirements for the degree of Master of Science, Department of Biomedical Engineering.
Thesis (Ph. D, Chemistry)--Northwestern University, 2000.
Motivated by ion mobility studies, molecular dynamics simulations have been carried out to study the unfolding, refolding and hydration of unsolvated protein ions. The temperature-induced unfolding...
