JSAT: Java Statistical Analysis Tool, a Library for Machine Learning
Java Statistical Analysis Tool (JSAT) is a Machine Learning library written in pure Java. It works to fill a void in the Java ecosystem for a general purpose library that is relatively high performance and flexible, which is not adequately fulfilled by Weka (Hall et al., 2009) and Java-ML (Abeel et al., 2009). Almost all of the algorithms are independently implemented using an Object-Oriented f...
متن کاملMachine Learning as a Tool for MicroRNA Analysis
Mature microRNAs (miRNA) are short (∼ 22 nucleotide), single-stranded, noncoding RNA strands that regulate gene expression. MiRNA expression in tissues is increasingly used to classify cell states and show promise as clinical biomarkers for diagnostics. In this report, we summarize our experience using three different Machine Learning (ML) algorithms to classify miRNA expression profiles in two...
متن کاملFurther Analysis of Stellar Magnetic Cycle Periods
We further investigate relationships between activity cycle periods in cool stars and rotation to include new cycle data, and explore different parameterizations of the problem. We find that relations between cycle and rotational frequencies (ωcyc vs. Ω) and between their ratio and the inverse Rossby number (ωcyc/Ω vs. Ro −1) show many similarities, including three branches and similar rms scat...
متن کاملStellar Ages from Stellar Rotation
Our ability to determine stellar ages from measurements of stellar rotation, hinges on how well we can measure the dependence of rotation on age for stars of different masses. Rotation periods for stars in open clusters are essential to determine the relations between stellar age, rotation, and mass (color). Until recently, ambiguities in v sin i data and lack of cluster membership information,...
متن کاملWavelet analysis of stellar differential rotation
A key mystery in stellar magnetohydrodynamics is knowledge of stellar differential rotation. At present, the only practical method for detecting the presence of surface differential rotation for slowly-rotating stars is through the indirect measurement of the stellar butterfly diagram: i.e., the change of rotation period determined from light modulation caused by the change in mean latitude of ...
