  • Asymptotics of Gaussian Regularized Least-Squares 

    Unknown author (2005-10-20)
    We consider regularized least-squares (RLS) with a Gaussian kernel. Weprove that if we let the Gaussian bandwidth $\sigma \rightarrow\infty$ while letting the regularization parameter $\lambda\rightarrow 0$, the RLS solution ...

  • AvatarSAT: An Auto-tuning Boolean SAT Solver 

    Unknown author (2009-08-26)
    We present AvatarSAT, a SAT solver that uses machine-learning classifiers to automatically tune the heuristics of an off-the-shelf SAT solver on a per-instance basis. The classifiers use features of both the input and ...

  • Cicada: Predictive Guarantees for Cloud Network Bandwidth 

    Unknown author (2014-03-24)
    In cloud-computing systems, network-bandwidth guarantees have been shown to improve predictability of application performance and cost. Most previous work on cloud-bandwidth guarantees has assumed that cloud tenants know ...

  • Classification of Breast Cancer Using Logistic Regression 

    Ude, Anthony Anene (2019-06-16)
    Breast cancer is a prevalent disease that affects mostly women, an early diagnosis will expedite the treatment of this ailment. In recent times, Machine Learning (ML) techniques have been employed in biomedical and informatics ...

  • Comparing Support Vector Machines with Gaussian Kernels to Radial Basis Function Classifiers 

    Unknown author (1996-12-01)
    The Support Vector (SV) machine is a novel type of learning machine, based on statistical learning theory, which contains polynomial classifiers, neural networks, and radial basis function (RBF) networks as special ...

  • Elastic-Net Regularization in Learning Theory 

    Unknown author (2008-07-24)
    Within the framework of statistical learning theory we analyze in detail the so-called elastic-net regularization scheme proposed by Zou and Hastie ["Regularization and variable selection via the elastic net" J. R. Stat. ...

  • Ensemble Learning for URL Phishing Detection 

    Igwilo, Chiamaka Mary (AUST, 2020-07-13)
    Phishing is a social engineering attack that has been perpetuated for long and is still a prominent attack with an attending high number of victims. The adverse effect of this allows phishers easy access to sensitive ...

    Igwilo, Chiamaka Mary (2021-07)
    Phishing is a social engineering attack that has been perpetuated for long and is still a prominent attack with an attending high number of victims. The adverse effect of this allows phishers easy access to sensitive ...

  • iBCM: Interactive Bayesian Case Model Empowering Humans via Intuitive Interaction 

    Unknown author (2015-04-01)
    Clustering methods optimize the partitioning of data points with respect to an internal metric, such as likelihood, in order to approximate the goodness of clustering. However, this internal metric does not necessarily ...

  • Learning World Models in Environments with Manifest Causal Structure 

    Unknown author (1995-05-05)
    This thesis examines the problem of an autonomous agent learning a causal world model of its environment. Previous approaches to learning causal world models have concentrated on environments that are too "easy" ...

  • Multi-Class Learning: Simplex Coding And Relaxation Error 

    Unknown author (2011-09-27)
    We study multi-category classification in the framework of computational learning theory. We show how a relaxation approach, which is commonly used in binary classification, can be generalized to the multi-class setting. ...

  • Multiscale Geometric Methods for Data Sets I: Multiscale SVD, Noise and Curvature 

    Unknown author (2012-09-08)
    Large data sets are often modeled as being noisy samples from probability distributions in R^D, with D large. It has been noticed that oftentimes the support M of these probability distributions seems to be well-approximated ...

  • Neural Networks 

    Unknown author (1996-03-13)
    We present an overview of current research on artificial neural networks, emphasizing a statistical perspective. We view neural networks as parameterized graphs that make probabilistic assumptions about data, and view ...

  • Nonparametric Sparsity and Regularization 

    Unknown author (2011-09-26)
    In this work we are interested in the problems of supervised learning and variable selection when the input-output dependence is described by a nonlinear function depending on a few variables. Our goal is to consider a ...

  • Planning Robust Strategies for Constructing Multi-object Arrangements 

    Unknown author (2017-01-30)
    A crucial challenge in robotics is achieving reliable results in spite of sensing and control uncertainty. A prominent strategy for dealing with uncertainty is to construct a feedback policy, where actions are chosen as a ...
