    • Efficient Image Reconstruction for Gigapixel Quantum Image Sensors 

      Chan, Stanley H.; Lu, Yue (IEEE, 2014)
      Recent advances in materials, devices and fabrication technologies have motivated a strong momentum in developing solid-state sensors that can detect individual photons in space and time. It has been envisioned that such ...
    • Finite dimensional FRI 

      Onativia, Jon; Lu, Yue; Dragoni, Pier Luigi (Institute of Electrical and Electronics Engineers, 2014)
      Traditional Finite Rate of Innovation (FRI) theory has considered the problem of sampling continuous-time signals. This framework can be naturally extended to the case where the input is a discrete-time signal. Here we ...
    • On Sparse Representation in Fourier and Local Bases 

      Dragotti, Pier Luigi; Lu, Yue (Institute of Electrical & Electronics Engineers (IEEE), 2014)
      We consider the classical problem of finding the sparse representation of a signal in a pair of bases. When both bases are orthogonal, it is known that the sparse representation is unique when the sparsity K of the signal ...
    • Problems in Signal Processing and Inference on Graphs 

      Agaskar, Ameya (2015-05-15)
      Modern datasets are often massive due to the sharp decrease in the cost of collecting and storing data. Many are endowed with relational structure modeled by a graph, an object comprising a set of points and a set of ...
    • Randomized Kaczmarz algorithms: Exact MSE analysis and optimal sampling probabilities 

      Agaskar, Ameya; Wang, Chuang; Lu, Yue (IEEE, 2014)
      The Kaczmarz method, or the algebraic reconstruction technique (ART), is a popular method for solving large-scale overdetermined systems of equations. Recently, Strohmer et al. proposed the randomized Kaczmarz algorithm, ...
    • Sensor placement for the analysis of seismic surface waves: sources of error, design criterion and array design algorithms 

      Maranò, Stefano; Fäh, Donat; Lu, Yue (Oxford University Press (OUP), 2014)
      Seismic surface waves can be measured by deploying an array of seismometers on the surface of the earth. The goal of such measurement surveys is, usually, to estimate the velocity of propagation and the direction of arrival ...
    • A Spectral Graph Regression Model for Learning Brain Connectivity of Alzheimer’s Disease 

      Hu, Chenhui; Cheng, Lin; Sepulcre, Jorge; Johnson, Keith A.; Fakhri, Georges E.; Lu, Yue M.; Li, Quanzheng (Public Library of Science, 2015)
      Understanding network features of brain pathology is essential to reveal underpinnings of neurodegenerative diseases. In this paper, we introduce a novel graph regression model (GRM) for learning structural brain connectivity ...
    • Subspace Estimation from Incomplete Observations: A High-Dimensional Analysis 

      Wang, Chuang; Eldar, Yonina C.; Lu, Yue (2017)
      We present a high-dimensional analysis of three popular algorithms, namely, Oja's method, GROUSE and PETRELS, for subspace estimation from streaming and highly incomplete observations.  We show that, with proper ...
