Nonparametric Bayesian Estimation of Periodic Functions
Yuyang Wang, Roni Khardon, Pavlos Protopapas
Many real world problems exhibit patterns that have periodic behavior. For example, in astrophysics, periodic variable stars play a pivotal role in understanding our universe. An i…
First Order Decision Diagrams for Relational MDPs
Chenggang Wang, Saket Joshi, Roni Khardon
Markov decision processes capture sequential decision making under uncertainty, where an agent must choose actions so as to optimize long term reward. The paper studies efficient r…
A Refined QSO Selection Method Using Diagnostics Tests: 663 QSO Candidates in the LMC
Dae-Won Kim, Pavlos Protopapas, Markos Trichas +4
We present 663 QSO candidates in the Large Magellanic Cloud (LMC) selected using multiple diagnostics. We started with a set of 2,566 QSO candidates from our previous work selected…
Efficiency versus Convergence of Boolean Kernels for On-Line Learning Algorithms
R. Khardon, D. Roth, R. A. Servedio
The paper studies machine learning problems where each example is described using a set of Boolean features and where hypotheses are represented by linear threshold elements. One m…
QSO Selection Algorithm Using Time Variability and Machine Learning: Selection of 1,620 QSO Candidates from MACHO LMC Database
Dae-Won Kim, Pavlos Protopapas, Yong-Ik Byun +3
We present a new QSO selection algorithm using a Support Vector Machine (SVM), a supervised classification method, on a set of extracted times series features including period, amp…
