Prior And Prediction Inverse Kernel Transformer For Single Image Defocus Deblurring, Peng Tang, Zhiqiang Xu, Chunlai Zhou, Pengfei Wei, Peng Han, Xin Cao, Tobias Lasser

Machine Learning Faculty Publications

Defocus blur, due to spatially-varying sizes and shapes, is hard to remove. Existing methods either are unable to effectively handle irregular defocus blur or fail to generalize well on other datasets. In this work, we propose a divide-and-conquer approach to tackling this issue, which gives rise to a novel end-to-end deep learning method, called prior-and-prediction inverse kernel transformer (P2IKT), for single image defocus deblurring. Since most defocus blur can be approximated as Gaussian blur or its variants, we construct an inverse Gaussian kernel module in our method to enhance its generalization ability. At the same time, an inverse kernel prediction …

Overcoming The Achievement Gap: Arkansas' Utilization Of Weighted Student Funding To Support Students Of Poverty, Michael G. Mcfetridge

ATU Theses and Dissertations 2021 - Present

With over 63% of its students living in poverty, the state of Arkansas has a challenge when it comes to equitable funding and opportunities for its students. One funding mechanism that has been in place in Arkansas for over 20 years now is a categorical funding allocation known as Enhanced Student Achievement Funds (ESA). School districts receive these funds based on their percentage of students in poverty. While this weighted student funding model of allocating more funds to identified characteristics has been in place in Arkansas for over two decades, little research exists to gauge whether these allocation mechanisms successfully …

Coping With California’S Deficit, Part 2: Permissible Borrowing, David Gamage, Darien Shanske

Faculty Publications

In this installment of Academic Perspectives on SALT, Shanske and Gamage examine California’s projected budget deficit and possible solutions. California has a large budget deficit that is predicted to last for several years. In this two-part series, we will place California’s situation in context and propose solutions.

The state should use short-term borrowing to cover at least some of the cyclical shortfall. That the real revenue cycle is unlikely to neatly unfold over one traditional fiscal year should not change this conclusion. To that end, we will show how California can operationalize this simple insight despite the impression some may …
